Thermostatisch gesteuerte MischbatterThermostatically controlled mixer tap

Die vorliegende Erfindung betrifft eine thermostatisch gesteuerte Mischbatterie, bei welcher die Temperatur des MischwasserStromes, der aus einem Heisswasserstrom und einem Kaltwasserstrom gebildet wird, durch automatische Regelung des Mischverhältnisses, auf einem voreinstellbaren Wert gehalten wird. Mischbatterien dieser Art sind bekannt geworden, sie besitzen eine Heisswasserkammer, eine Kaltwasserkammer und eine Mischwasserkammer, wobei die Heisswasserkammer und die Kaltwasserkammer über je ein Ventil mit der Mischwasserkammer verbunden sind, und in der Mischwasserkammer ein Temperaturfühler angeordnet ist, welcher zu jeder Temperatur des Mischwassers eine ganz bestimmte Kraft in Achsrichtung entwickelt, mit der er auf ein in Achsrichtung bewegliches, die Ventilorgane umfassendes System drückt. Dieses System wird durch eine Steuerfeder, deren Kraft mit einem Regulierorgan für die Mischwassertemperatur von Hand einstellbar ist, im Gleichgewicht gehalten.The present invention relates to a thermostatically controlled mixer tap, in which the temperature of the mixed water flow, which is formed from a hot water flow and a cold water flow, is kept at a presettable value by automatic regulation of the mixing ratio. Mixer taps of this type are known, they have a hot water chamber, a cold water chamber and a mixed water chamber, the hot water chamber and the cold water chamber are each connected to the mixed water chamber via a valve, and a temperature sensor is arranged in the mixed water chamber, which has a temperature sensor for each temperature of the mixed water developed a certain force in the axial direction, with which he presses on a system that is movable in the axial direction and includes the valve elements. This system is controlled by a control spring, the force of which can be adjusted manually with a regulating element for the mixed water temperature Kept balance.

Ferner ist. das bewegliche System mit einem von Hand zu betätigenden Regulierorgan für die Mischwassermenge verbunden, mit welchem der Abstand der Ventilorgane zur Regelung der Mischwassermenge verändert werden kann.Furthermore is. the movable system is connected to a manually operated regulating element for the mixed water quantity, with which the distance of the valve elements for regulating the mixed water quantity can be changed.

Bei Mischbatterien der genannten Art ist Fehlverhalten bei der Temperatursteuerung festzustellen. So treten bei schneller Aenderung der gewünschten Mischwassertemperatur am entsprechenden Regulierorgan, aber auch bei schneller Aenderung der gewünschten Mischwassermenge am entsprechenden Regulierorgan zum Teil grosse Schwankungen der Mischwassertemperatur auf. Ferner sind bei stark sich ändernder Druckdifferenz oder Temperaturdifferenz zwischen dem Heisswasser und dem Kaltwasser zum Teil grosse Abweichungen der tatsächlichen Mischwassertemperatur zur eingestellten Mischwassertemperatur festzustellen.In the case of mixer taps of the type mentioned, malfunctions in temperature control can be determined. Thus, when the desired mixed water temperature changes quickly at the corresponding regulating member, but also when the desired mixed water quantity changes rapidly at the corresponding regulating member, large fluctuations in the mixed water temperature sometimes occur. Furthermore, when the pressure difference or temperature difference between the hot water and the cold water changes rapidly, large deviations of the actual mixed water temperature from the set mixed water temperature can be determined.

Es ist nun der Zweck der vorliegenden Erfindung, eine Mischbatterie zu schaffen, bei welcher die Mischwassertemperatur trotz ungünstiger Voraussetzungen schnell und genau auf den eingestellten Wert geregelt wird.It is now the purpose of the present invention to provide a mixer tap in which the mixed water temperature is regulated quickly and precisely to the set value despite unfavorable conditions.

Der Aufbau der Mischbatterie ist nun gemäss der vorliegenden Erfindung dadurch gekennzeichnet, dass die Heisswasserkammer und die Kaltwasserkammer ringförmig nebeneinander, durch eine Wand getrennt, die Mischwasserkammer mit dem Temperaturfühler umschliessen, wobei an der radial nach innen verlängerten Wand zwischen der Heisswasserkammer und der Kaltwasserkammer zu beiden Seiten die Ventile so angeordnet sind, dass die zwei Wasserströme direkt auf den Temperaturfühler treffen und sich vermischen. So ist eine schnelle Reaktion des Temperaturfühlers auf Aenderungen der Mischwassertemperatur auch bei kleiner Mischwassermenge möglich. Weiter gekennzeichnet dadurch, dass sich die auf das bewegliche System drückende Steuerfeder an einer Steuerschraube, und diese mit einem Gewinde am Regulierorgan für die Mischwassertemperatur, und dieses wiederum an einer Lagerscheibe abstützt, welche ihrerseits durch mindestens 2 Schrauben oder gleichwertige Verbindungselemente starr mit dem Mischergehäuse verbunden ist. Mit dieser starren Verbindung wird gleichzeitig die Steuerschraube unmittelbar oder mittelbar am Verdrehen gehindert, welche so durch drehen am Regulierorgan für die Mischwassertemperatur in Achsrichtung bewegt werden kann und dabei die Steuerfeder spannt oder entspannt. Bei einer solchen Anordnung der Teile ist bei gegebenem äusseren Durchmesser des Regulierorgans für die Mischwassertemperatur ein grosser Gewindedurchmesser möglich. Dadurch wird bei gegebenem Steigungswinkel des Gewindes ein grosser Hub der Steuerschraube pro Drehwinkel des Regulierorgans für die Mischwassertemperatur erreicht. Dieses wiederum ist die Voraussetzung für eine genaue Regelung der Mischwassertemperatur, weil dadurch bei gegebener Kraft des Temperaturfühlers pro Grad Temperaturänderung des Mischwassers ein grosser Hub der Ventilorgane möglich ist.The structure of the mixer tap is now characterized according to the present invention in that the The hot water chamber and the cold water chamber are arranged next to one another in a ring, separated by a wall, and enclose the mixed water chamber with the temperature sensor, with the valves on the radially inward elongated wall between the hot water chamber and the cold water chamber being arranged on both sides so that the two water flows directly onto the temperature sensor meet and mix. This enables the temperature sensor to react quickly to changes in the mixed water temperature, even with a small amount of mixed water. Further characterized in that the control spring pressing on the movable system is supported on a control screw, and this with a thread on the regulating element for the mixed water temperature, and this in turn is supported on a bearing washer, which in turn is rigidly connected to the mixer housing by at least 2 screws or equivalent connecting elements is. With this rigid connection, the control screw is prevented directly or indirectly from twisting, which can be moved in the axial direction by turning the regulating element for the mixed water temperature and thereby tensioning or relaxing the control spring. With such an arrangement of the parts, a large thread diameter is possible for the mixed water temperature given the outer diameter of the regulating member. As a result, at a given pitch angle of the thread A large stroke of the control screw per angle of rotation of the regulating element for the mixed water temperature is reached. This, in turn, is the prerequisite for precise control of the mixed water temperature because, given the force of the temperature sensor, a large stroke of the valve elements is possible for each degree of change in temperature of the mixed water.

Die Erfindung soll anschliessend anhand der Zeichnung beispielsweise näher erläutert werden, wobei darstellt: Fig. 1 eine Mischbatterie im Längsschnitt. Fig. 2 eine Variante eines Details der Mischbatterie der Fig. 1 im gleichen Massstab . Die Mischbatterie besteht aus einem unterteilten Gehäuse 1, wobei die drei Einzelteile des Gehäuses 1 mit 1a, 1b und 1c bezeichnet sind. Die Gehäuseteile 1a und 1b sind, wie bei ld angedeutet, fest und wasserdicht zusammengefügt. Ebenfalls sind die Gehäuseteile 1a und 1c, wie bei 1e angedeutet, fest und wasserdicht zusammengefügt. Der Gehäuseteil 1a enthält den Kaltwasserzuflussstutzen 2 und den Heisswasserzuflussstutzen 3. Der Gehäuseteil 1b enthält den Mischwasseräbflussstutzen 4. Der Kaltwasserzuflussstutzen 2 ist mit der Kaltwasserkammer 5 verbunden und der Heisswasserzuflussstutzen 3 ist mit der Heisswasserkammer 6 verbunden. Konzentrisch zu diesen ringförmigen Kammern liegt die mit 7 bezeichnete Mischwasserkammer, die mit dem Mischwasserabflussstutzen 4 verbunden ist. Die Heisswasserkammer 6 ist mit der Mischwasserkammer 7 über das allgemein mit 8 bezeichnete Ventil verbunden. Das Ventil 8 enthält einen Ventilsitz 8a, der durch die radial nach innen verlängerte Wand zwischen der Kaltwasserkammer 5 und der Heisswasserkammer 6 gebildet wird. Weiter enthält das Ventil 8 ein Ventilorgan 8b, das, wie in der Darstellung gezeigt, auf dem Uebertragungsorgan 9 befestigt ist und mit diesem in Achsrichtung bewegt werden kann. An der dem Ventilsitz 8a zugewandten Stirnfläche des Ventilorgans 8b ist ein O-Ring 8c eingespannt, der in der Schliessstellung des Ventils 8 aus dem Ventilsitz 8a aufliegt und die Verbindung zwischen der Heisswasserkammer 6 und der Mischwasserkammer 7 unterbricht. Das dem Ventilsitz 8a abgewandte Ende 8d des Ventilorgans 8b ist im Gehäuse 1b in Achsrichtung beweglich geführt und mit einem O-Ring 8e versehen, der die Heisswasserkammer 6 gegen die Mischwasserkammer 7 abdichtet. Das Ende 8d des Ventilorgans 8b hat einen Durchmesser, welcher wenigstens annähernd gleich gross ist wie der mittlere Durchmesser des O-Ringes 8c. Durch die Gleichheit der abzudichtenden Durchmesser an den Enden des Ventilorgans 8b wird erreicht, dass der Druck in der Heisswasserkammer 6 keine axiale Kraft auf das bewegliche Ventilorgan 8b zur Folge hat. Es ist ohne weiteres zu erkennen, dass sich alle von dem Druck des Heisswassers verursachten, in Achsrichtung wirkenden Kräfte kompensieren. Die Stellung des beweglichen Ventilorgans 8b kann somit nicht vom Druck des Heisswassers beeinflusst werden. Da, wie noch zu zeigen sein wird, die Stellung des Ventilorgans 8b das Mischverhältnis von Heiss- und Kaltwasser beeinflusst, bedeutet die gezeigte Druckkompensation, dass die Temperatur des Mischwassersnicht vom Druck des Heisswassers abhängig ist. Eine im wesentlichen gleiche Konstruktion ist das allgemein mit 10 bezeichnete Ventil, bei dem auf gleiche Art die Kompensation der durch den Druck in der Kaltwasserkammer 5 verursachten axialen Kräfte erreicht wird. Das Ventil 10 enthält einen Ventilsitz 10a, der durch die radial nach innen verlängerte Wand zwischen der Heisswasserkammer 6 und der Kaltwasserkammer 5 gebildet wird. Die Ventilsitze 8a und 10a befinden sich also zu beiden Seiten der radial nach innen verlängerten Wand zwischen der Heisswasserkammer und der Kaltwasserkammer. Weiter enthält das Ventil 10 ein Ventilorgan 10b, welches ebenfalls auf dgm Uebertragungsorgan 9 befestigt ist und mit diesem in Achsrichtung bewegt werden kann. An der dem Ventilsitz 10a zugewandten Stirnseite des Ventilorgans 10b ist ein O-Ring 10c eingespannt, der in der Schliessstellung des Ventils 10 auf dem Ventilsitz 10a aufliegt und die Verbindung zwischen der Kaltwasserkammer 5 und der Mischwasserkammer 7 unterbricht. Das dem Ventilsitz 10a abgewandte Ende 10d des Ventilorgans 10b ist im Gehäuseteil 1c in Achsrichtung beweglich geführt und mit einem O-Ring 10e versehen, der die Kaltwasserkammer 5 gegen die Vorderkammer 11 abdichtet. Damit ein schneller Druckausgleich zwischen der Mischwasserkammer 7 und der Vorderkammer 11 gewährleistet ist, ist die Vorderkammer 11 mit der Mittelkammer 12 durch die Oeffnungen 10f, in der Darstellung, in der oberen Stirnseite des Ventilorgans 10b verbunden, während die Mittelkammer 12 mit der Mischwasserkammer 7 durch die Oeffnungen 8f, in der Darstellung, in der oberen Stirnseite des Ventilorgans 8b verbunden ist. In der Mittelkammer 12 befindet sich eine Tellerfeder 14, deren Kraft versucht den axialen Abstand der Ventilorgane 8b und 10b zu vergrössern. Zusammengehalten werden die zwei Ventilorgane 8b und 10b durch das Uebertragungsorgan 9, wobei das Ventilorgan 8b sich an der Schulter 9a des Uebertragungsorgans 9 abstützt, während das Ventilorgan 10b sich über den Flansch 15 an der Mutter 16 abstützt, welche mittels des Gewindes 16a mit dem Uebertragungsorgan 9 verbunden ist. Die Führung des Uebertragungsorgans 9 im Flansch 15 ist mit dem O-Ring 9b abgedichtet.The invention will subsequently be explained in more detail with reference to the drawing, for example: FIG. 1 shows a mixer tap in longitudinal section. Fig. 2 shows a variant of a detail of the mixer tap of Fig. 1 on the same scale. The mixer tap consists of a subdivided housing 1, the three individual parts of the housing 1 being designated by 1a, 1b and 1c. The housing parts 1a and 1b are, as indicated at ld, assembled firmly and watertight. Also, as indicated at 1e, the housing parts 1a and 1c are joined firmly and watertight. The housing part 1 a contains the cold water inlet connector 2 and the hot water inlet connector 3. The housing part 1 b contains the mixed water outlet connector 4. The cold water inlet connector 2 is connected to the cold water chamber 5 and the hot water inlet connector 3 is connected to the hot water chamber 6. Concentric to these annular chambers is the mixed water chamber, designated 7, which is connected to the mixed water outflow connection 4. The hot water chamber 6 is connected to the mixed water chamber 7 via the valve generally designated 8. The valve 8 contains a valve seat 8a, which is formed by the radially inwardly elongated wall between the cold water chamber 5 and the hot water chamber 6. Furthermore, the valve 8 contains a valve element 8b which, as shown in the illustration, is fastened on the transmission element 9 and can be moved with it in the axial direction. On the end face of the valve element 8b facing the valve seat 8a, an O-ring 8c is clamped, which rests in the closed position of the valve 8 from the valve seat 8a and interrupts the connection between the hot water chamber 6 and the mixed water chamber 7. The end 8d of the valve member 8b facing away from the valve seat 8a is movably guided in the housing 1b in the axial direction and is provided with an O-ring 8e which seals the hot water chamber 6 against the mixed water chamber 7. The end 8d of the valve member 8b has a diameter which is at least approximately the same size as the average diameter of the O-ring 8c. The equality of the diameter to be sealed at the ends of the valve member 8b ensures that the pressure has no axial force on the movable valve member 8b in the hot water chamber 6. It can easily be seen that all forces acting in the axial direction caused by the pressure of the hot water are compensated for. The position of the movable valve member 8b can therefore not be influenced by the pressure of the hot water. Since, as will be shown later, the position of the valve member 8b influences the mixing ratio of hot and cold water, the pressure compensation shown means that the temperature of the mixed water is not dependent on the pressure of the hot water. An essentially identical construction is the valve, generally designated 10, in which the compensation of the axial forces caused by the pressure in the cold water chamber 5 is achieved in the same way. The valve 10 contains a valve seat 10a, which is formed by the radially inwardly elongated wall between the hot water chamber 6 and the cold water chamber 5. The valve seats 8a and 10a are therefore located on both sides of the radially inwardly elongated wall between the hot water chamber and the cold water chamber. Furthermore, the valve 10 contains a valve member 10b, which is also attached to the transmission member 9 and can be moved with it in the axial direction. On the face of the valve seat 10a facing the Valve member 10b is clamped in an O-ring 10c, which rests on valve seat 10a in the closed position of valve 10 and interrupts the connection between cold water chamber 5 and mixed water chamber 7. The end 10d of the valve member 10b facing away from the valve seat 10a is movably guided in the housing part 1c in the axial direction and provided with an O-ring 10e which seals the cold water chamber 5 against the front chamber 11. In order to ensure rapid pressure equalization between the mixed water chamber 7 and the front chamber 11, the front chamber 11 is connected to the central chamber 12 through the openings 10f, in the illustration, in the upper end face of the valve member 10b, while the central chamber 12 is connected to the mixed water chamber 7 the openings 8f, in the illustration, are connected in the upper end face of the valve element 8b. In the middle chamber 12 there is a plate spring 14, the force of which tries to increase the axial distance between the valve members 8b and 10b. The two valve elements 8b and 10b are held together by the transmission element 9, the valve element 8b being supported on the shoulder 9a of the transmission element 9, while the valve element 10b is supported via the flange 15 on the nut 16, which is connected to the transmission element by means of the thread 16a 9 is connected. The Guide of the transmission member 9 in the flange 15 is sealed with the O-ring 9b.

Wird nun am Regulierorgan für die Mischwassermenge 17 gedreht, so dreht sich das Vierkant 17b, da es über die Achse 17a mit dem Regulierorgan für die Mischwassermenge 17 starr verbunden ist. Das Vierkant 17b ist formschlüssig, in Achsrichtung leicht verschiebbar, mit der Mutter 16 gekuppelt, und überträgt die Drehung auf diese. Das Uebertragungsorgan 9 ist durch den Querstift 18 gegen Verdrehen gesichert, welcher in einem Schlitz 15a des Flansches 15 nur in Achsrichtung verschiebbar ist. Der Flansch 15 wiederum ist durch die Schrauben 19 gegen Verdrehen gesichert und nur in Achsrichtung verschiebbar. Weiter ist der Flansch 15 im Gehäuseteil 1c in Achsrichtung beweglich geführt. Diese Führung ist mit dem O-Ring 15b abgedichtet. Durch die Drehung der Mutter 16 gegenüber dem Uebertragungsorgan 9 schraubt sich die Mutter auf Grund des Gewindes 16a zum Beispiel nach oben in der Darstellung. Die Tellerfeder 14 schiebt nun das Ventilorgan 10b und den Flansch 15 nach. Dadurch vergrössert sich der Abstand zwischen den O-Ringen 8c und 10c der entsprechenden Ventilorgane 8b und 10b. Die Ventilorgane 8b und 10b gehören zum beweglichen System und somit ist nicht festgelegt, ob das Kaltwasserventil 10 oder das Heisswasserventil 8 sich öffnet. Das bewegliche System umfasst das Uebertragungsorgan 9, auf welchem die Ventilorgane 8b und 10b mit den dazugehörenden O-Ringen 8c, 8e und 10c, 10e, die Tellerfeder 14, der Flansch 15 und die Mutter 16 angeordnet sind. Dieses System ist durch die Vorspannung der Tellerfeder 14 in sich starr und bewegt sich als Ganzes in Achsrichtung. Dabei werden die Abstände der O-Ringe 8c und 10c zu den entsprechenden Ventilsitzen 8a und 10a wechselseitig verändert.If the regulator for the mixed water quantity 17 is now rotated, the square 17b rotates, since it is rigidly connected to the regulator for the mixed water quantity 17 via the axis 17a. The square 17b is form-fitting, easily displaceable in the axial direction, coupled to the nut 16, and transmits the rotation to it. The transmission element 9 is secured against rotation by the transverse pin 18, which can only be displaced in the axial direction in a slot 15a of the flange 15. The flange 15 is in turn secured by the screws 19 against rotation and can only be moved in the axial direction. Furthermore, the flange 15 is guided movably in the axial direction in the housing part 1c. This guide is sealed with the O-ring 15b. Due to the rotation of the nut 16 with respect to the transmission element 9, the nut screws upward in the illustration, for example, due to the thread 16a. The plate spring 14 now pushes the valve member 10b and the flange 15. This increases the distance between the O-rings 8c and 10c of the corresponding valve members 8b and 10b. The valve members 8b and 10b belong to the movable system and therefore it is not determined whether the cold water valve 10 or the hot water valve 8 opens. The movable system comprises the transmission element 9, on which the valve elements 8b and 10b with the associated O-rings 8c, 8e and 10c, 10e, the plate spring 14, the flange 15 and the nut 16 are arranged. This system is inherently rigid due to the prestressing of the plate spring 14 and moves as a whole in the axial direction. The distances of the O-rings 8c and 10c to the corresponding valve seats 8a and 10a are mutually changed.

Ist nun zum Beispiel das allgemein mit 8 bezeichnete Ventil und das allgemein mit 10 bezeichnete Ventil geöffnet, dann strömt das Heisswasser zwischen dem O-Ring 8c und dem Ventilsitz 8a hindurch und das Kaltwasser zwischen dem O-Ring 10c und dem Ventilsitz 10a hindurch. Nebeneinander gelangen die zwei Wasserstrδme mit grosser Geschwindigkeit durch die am Umfang des Ventilorgans 8b vorhandenen Oeffnungen 8g auf kürzestem Weg zum allgemein mit 13 bezeichneten Temperaturfühler. Während das Heisswasser und das Kaltwasser auf dem Temperaturfühler 13 aufprallen, findet eine intensive Vermischung beider Wasserströme statt, und das Mischwasser strömt zum Mischwasserabflussstutzen 4, in der Darstellung unten.For example, if the valve generally designated 8 and the valve generally designated 10 are open, then the hot water flows between the O-ring 8c and the valve seat 8a and the cold water between the O-ring 10c and the valve seat 10a. The two water streams reach each other at high speed through the openings 8g provided on the circumference of the valve element 8b by the shortest route to the temperature sensor, generally designated 13. While the hot water and the cold water hit the temperature sensor 13, an intensive mixing of both water flows takes place, and the mixed water flows to the mixed water drainage connection 4, in the illustration below.

Der allgemein mit 13 bezeichnete Temperaturfühler ist am unteren Ende in der Darstellung mit dem Gehäuseteil 1b fest verbunden, wie es bei 13a angedeutet ist. Also gehört der Temperaturfühler 13 nicht zum beweglichen System. Folglich können die durch das strömende Mischwasser verursachten Kräfte auf den Temperaturfühler 13 die Steuerung der Mischwassertemperatur nicht beeinflussen.The temperature sensor, generally designated 13, is at the lower end in the illustration with the housing part 1b firmly connected, as indicated at 13a. So the temperature sensor 13 is not part of the movable system. Consequently, the forces on the temperature sensor 13 caused by the flowing mixed water cannot influence the control of the mixed water temperature.

Der Temperaturfühler 13 besteht aus dem Temperaturfühlergehäuse 13b, welches wie bei 13c angedeutet mit dem Sockel 13d verlötet ist. Im Temperaturfühlergehäuse 13b ist ein Faltenbalg 13e angeordnet, welcher oben in der Darstellung mit dem Sockel 13d, und unten in der Darstellung mit dem Teller 13f verbunden ist. Der Teller 13f ist mit der Stange 13g verbunden, welche am oberen Ende in der Darstellung gegen das Uebertragungsorgan 9 drückt. Das Uebertragungsorgan 9 ist im Sockel 13d in Achsrichtung beweglich geführt. Diese Führung ist mit dem O-Ring 13i abgedichtet. Der Zwischenraum zwischen dem Faltenbalg 13e und dem Temperaturfühlergehäuse 13b ist mit einem Steuermedium 13h teilweise gefüllt. Dieses Steuermedium ist vorzugsweise ein in dem gesamten zu regelnden Temperaturbereich im Sattdampfzustand verharrender Stoff, wie beispielsweise ein halogensubstituierter Kohlenwasserstoff. Stoffe dieser Art sind unter der Handelsbezeichnung "FREON" erhältlich. Der Innenraum 13j des Temperaturfühlers 13 ist durch die Bohrung 9c im Uebertragungsorgan 9 und durch den Schlitz 13k im Ende der Stange 13g mit der Umgebung der Mischbatterie verbunden, damit als Folge von Temperaturschwankungen im Innenraum 13d keine DruckSchwankungen auftreten können. Wie leicht zu erkennen ist, würde eine Aenderung des Druckes im Innenraum 13j die Steuerung der Mischwassertemperatur beeinflussen, da die wirksame Fläche des Faltenbalges 13e nicht gleich gross ist wie die wirksame Fläche des Uebertragungsorgans 9. Hat nun der Temperaturfühler 13 die Temperatur des Mischwassers angenommen, so gehört zu dieser Mischwassertemperatur ein ganz bestimmter Dampfdruck des Steuermediums 13h und als Folge davon eine ganz bestimmte Kraft der Stange 13g auf das Uebertragungsorgan 9 und somit auf das bewegliche System.The temperature sensor 13 consists of the temperature sensor housing 13b which, as indicated at 13c, is soldered to the base 13d. A bellows 13e is arranged in the temperature sensor housing 13b, which is connected to the base 13d at the top in the illustration and to the plate 13f at the bottom in the illustration. The plate 13f is connected to the rod 13g, which in the illustration presses against the transmission element 9 at the upper end. The transmission element 9 is movably guided in the axial direction in the base 13d. This guide is sealed with the O-ring 13i. The gap between the bellows 13e and the temperature sensor housing 13b is partially filled with a control medium 13h. This control medium is preferably a substance which remains in the saturated steam state in the entire temperature range to be regulated, such as, for example, a halogen-substituted hydrocarbon. Fabrics of this type are available under the trade name "FREON". The interior 13j of the temperature sensor 13 is through the bore 9c in the transmission element 9 and through the slot 13k in the end of the rod 13g connected to the surroundings of the mixer tap so that no pressure fluctuations can occur as a result of temperature fluctuations in the interior 13d. As can easily be seen, a change in the pressure in the interior 13j would influence the control of the mixed water temperature, since the effective area of the bellows 13e is not the same size as the effective area of the transmission element 9. If the temperature sensor 13 has now assumed the temperature of the mixed water, So this mixed water temperature includes a very specific vapor pressure of the control medium 13h and, as a result, a very specific force of the rod 13g on the transmission element 9 and thus on the movable system.

Das bewegliche System wird durch die Kraft der Steuerfeder 20, welche auf dem Kragen des Flansches 15 aufliegt, im Gleichgewicht gehalten. Das bewegliche System befindet sich also dann in Achsrichtung im Gleichgewicht, wenn die Mischwassertemperatur so hoch ist, dass die dazugehörende Kraft, als Folge des Dampfdruckes, gleich gross ist wie die Kraft der Steuerfeder 20. Die Steuerfeder 20 stützt sich am Kragen 21b der Steuerschraube 21 ab. Durch die Schlitze 21a im Kragen 21b, durch welche die Schrauben 19 hindurchgehen, ist die Steuerschraube 21 nur in Achsrichtung beweglich. Die Steuerschraube 21 stützt sich in Achsrichtung über das Gewinde 21c am Regulierorgan für die Mischwassertemperatur 22 ab, welches seinerseits durch die LagerScheibe 23 und diese durch die Schrauben 19 gehalten wird. Durch drehen am Regulierorgan für die Mischwassertemperatur 22 bewegt sich die Steuerschraube 21 mittels des Gewindes 21c zum Beispiel nach unten in der Darstellung. Die Steuerfeder 20 wird komprimiert und somit wird die Kraft auf den Kragen des Flansches 15 grosser und als Folge bewegt sich das bewegliche System nach unten in der Darstellung. Das Ventil 10 für das Kaltwasser schliesst sich etwas, während das Ventil 8 für das Heisswasser sich etwas öffnet. Als Folge steigt die Mischwassertemperatur und somit die über den Dampfdruck des Steuermediums 13h erzeugte Kraft auf das bewegliche System. Die Temperatur des Mischwassers stellt sich nun so ein, dass die vom Steuermedium ausgehende Kraft gleich der voreingestellten Kraft der Steuerfeder 20 ist.The movable system is balanced by the force of the control spring 20, which rests on the collar of the flange 15. The movable system is in equilibrium in the axial direction when the mixed water temperature is so high that the associated force, as a result of the vapor pressure, is the same as the force of the control spring 20. The control spring 20 is supported on the collar 21b of the control screw 21 from. Through the slots 21a in the collar 21b, through which the screws 19 pass, the Control screw 21 only movable in the axial direction. The control screw 21 is supported in the axial direction via the thread 21c on the regulating member for the mixed water temperature 22, which in turn is held by the bearing disk 23 and this by the screws 19. By turning the regulating element for the mixed water temperature 22, the control screw 21 moves by means of the thread 21c, for example downwards in the illustration. The control spring 20 is compressed and thus the force on the collar of the flange 15 is greater and as a result the movable system moves down in the illustration. The valve 10 for the cold water closes somewhat, while the valve 8 for the hot water opens somewhat. As a result, the mixed water temperature and thus the force generated by the vapor pressure of the control medium 13h on the movable system. The temperature of the mixed water is now such that the force emanating from the control medium is equal to the preset force of the control spring 20.

Analog verläuft die Steuerung der Mischwassertemperatur, wenn sich während des Betriebes beispielsweise die Temperatur des durch den Heisswasserzuflussstutzen 3 zufliessenden Wassers verringert. Es sinkt dann die Mischwassertemperatur und als Folge davon sinkt der Dampfdruck des Steuermediums und somit wird die Kraft auf das bewegliche System kleiner. Da die Kraft der Steuerfeder 20 unverändert geblieben ist, bewegt sich das ganze in Achsrichtung bewegliche System nach unten in der Darstellung. So wird die Kaltwasserzufuhr verringert und die Heisswasserzufuhr vergrössert, bis die Mischwassertemperatur wieder so hoch ist, dass die über den Dampfdruck erzeugte Kraft auf das bewegliche System gleich der Kraft der Steuerfeder 20 ist.The control of the mixed water temperature is analogous if, for example, the temperature of the water flowing in through the hot water inflow nozzle 3 decreases during operation. The mixed water temperature then drops and as a result the Vapor pressure of the control medium and thus the force on the moving system becomes smaller. Since the force of the control spring 20 has remained unchanged, the entire system movable in the axial direction moves downward in the illustration. The cold water supply is reduced and the hot water supply is increased until the mixed water temperature is again so high that the force generated by the steam pressure on the movable system is equal to the force of the control spring 20.

Die Fig.2 zeigt eine Variante eines Details deα? Fig.l. In dieser Variante sind die zwei O-Ringe 8c und 10c nicht in den entsprechenden Ventilorganen 8b und 10b eingespannt, sondern in den entsprechenden Ventilsitzen 8a und 10a zu beiden Seiten der radial nach innen verlängerten Wand zwischen Heisswasserkammer 6 und Kaltwasserkammer 5.2 shows a variant of a detail of α? Fig.l. In this variant, the two O-rings 8c and 10c are not clamped in the corresponding valve members 8b and 10b, but rather in the corresponding valve seats 8a and 10a on both sides of the radially inwardly elongated wall between the hot water chamber 6 and the cold water chamber 5.

Selbstverständlich sind eine Reihe weiterer Abänderungen von dem gezeigten Beispiel möglich. So kann beispielsweise der Abstand der Ventilorgane 8b und 10b des beweglichen Systems unveränderbar sein und die Regulierung der Mischwassermenge durch ein Ventil nach der Mischwasserkammer erfolgen. So kann beispielsweise der Flansch 15 aus einem Kragen und einer Hülse zusammengesetzt sein, wobei nur der Kragen für die Verdreh- Sicherung des Uebertragungsorgans 9 verwendet wird.Of course, a number of other modifications of the example shown are possible. For example, the distance between the valve members 8b and 10b of the movable system can be unchangeable and the amount of mixed water can be regulated by a valve after the mixed water chamber. For example, the flange 15 can be composed of a collar and a sleeve, with only the collar for the Securing the transmission organ 9 is used.

Die anhand der Fig. 1 und 2 beispielsweise erläuterte Mischbatterie gewährleistet eine genaue Temperaturregelung des ausfliessenden Mischwassers. Dabei sind insbesondere, durch die kurzen Strömungswege von den Ventilen zum Temperaturfühler und durch schnelles Mischen der beiden Wasserströme, Schwankungen der Mischwassertemperatur als Folge von schnellem Betätigen der Regulierorgane praktisch nicht festzustellen. The mixer tap, for example explained with reference to FIGS. 1 and 2, ensures precise temperature control of the outflowing mixed water. In particular, due to the short flow paths from the valves to the temperature sensor and the rapid mixing of the two water flows, fluctuations in the mixed water temperature as a result of the rapid actuation of the regulating elements are practically undetectable.
