Die Nuten 16 sind zur Zusammenwirkung mit Steueröffnungen 19 bestimmt, die am Umfang jeder Zylinderbohrung 2 an beiden Seiten der Nut 16 ausgebildet sind und durch die Mündungen von Kanälen 21 für die Zufuhr bzw. die Ableitung des Druckmittels gebildet werden. Am unteren Ende aes Kolbens 3 ist eine hydrostatische Schmiertasche 43 ausgebildet, die durch Bohrungen 41, 42 mit dem Zylinderraum über dem Kolben 3 in Verbindung stehtEach piston 3 is provided with grooves 16 running in the axial direction of the piston, which lead from the end face 17 of the piston, are in communication with the cylinder space of the cylinder bore 2 and end in an intermediate region of the length of the piston. The grooves 16 are intended to interact with control openings 19 which are formed on the circumference of each cylinder bore 2 on both sides of the groove 16 and are formed by the mouths of channels 21 for the supply and discharge of the pressure medium. A hydrostatic lubrication pocket 43 is formed at the lower end of a piston 3 and communicates with the cylinder space above piston 3 through bores 41, 42
Die unteren Enden der Kolben 3 sind mit flanschartigen Vorsprängen 23 versehen, die an einer Seite einen Hebelarm 24 bilden, in welchem ein Führungsschlitz ausgebildet ist. Im Führungsschlitz ist ein Zapfen 26 geführt, der am Stein 5 befestigt ist, wobei zwischen dem Zapfen 26 und dem Führungsschlitz ein nicht dargestellter Gleitstein angeordnet sein kann.The lower ends of the piston 3 are provided with flange-like projections 23 on one side form a lever arm 24 in which a guide slot is formed. There is a Guided pin 26, which is attached to the stone 5, between the pin 26 and the guide slot a sliding block, not shown, can be arranged.
An beiden Seiten des Zylinderblocks 1 sind seitliche Deckel 30, 31 befestigt, in welchen Ringkanäle 32, 33, 34 und 35 ausgebildet sind. Je ein Paar der Kanäle an jeder Seite des Zylinderblocks 1, z. B. die Kanäle 32 und 34, sind mit den Steueröffnungen 19 verbunden und dienen zur Ableitung des Druckmittels, das andere Paar 33, 35 mit nicht dargestellten, neben den öffnungen 19 befindlichen Stetieröffnungen und dienen zu seiner Zufuhr. Die Ringkanäle sind durch Taschen 36, 37 mit den zugehörigen Steueröffnungen bzw. Kanälen verbunden.On both sides of the cylinder block 1, side covers 30, 31 are attached, in which ring channels 32, 33, 34 and 35 are formed. A pair of channels on each side of the cylinder block 1, e.g. B. the Channels 32 and 34 are connected to the control openings 19 and serve to divert the pressure medium, the other pair 33, 35 with continuous openings, not shown, located next to the openings 19 and serve for its supply. The ring channels are through pockets 36, 37 with the associated Control openings or channels connected.
Da die Ausführung dieses Teiles der Kolbenmaschine nicht zum Gegenstand der Erfindung gehört, kann auf eine weitere Beschreibung verzichtet werden, wobei ausdrücklich auf die beiden erwähnten Patentschriften, in welchen ihre Funktion genau beschrieben ist, hingewiesen wird.Since the execution of this part of the piston machine is not part of the subject matter of the invention, A further description can be dispensed with, with the two mentioned expressly being used Patent specifications, in which their function is described in detail, is pointed out.
Erfindungsgemäß ist die in den F i g. 1 bis 3 dargestellte Kolbenmaschine mit einer Führungsanordnung versehen, welche zwei senkrecht zueinander geradlinig bewegliche Teile 50 und 51 enthält. Der TeilAccording to the invention is shown in FIGS. 1 to 3 shown piston machine with a guide arrangement which contains two parts 50 and 51 which can be moved in a straight line perpendicular to one another. The part
50 ist nach der F i g. 2 in vertikaler Richtung an zwei Vorsprängen 52 des Gehäuses, die am Deckel 31 ausgebildet sind, geführt. Der Teil 50 ist zu diesem Zweck mit entsprechenden Nuten versehen und umschließt, wie aus der F i g. 3 hervorgeht, die Vorspränge 52.50 is according to FIG. 2 in the vertical direction on two projections 52 of the housing, which are attached to the cover 31 are trained, performed. For this purpose, the part 50 is provided with appropriate grooves and encloses as shown in FIG. 3, the projections 52.
Seitlich ist der Teil 50 ebenfalls mit Nuten versehen, in welchen Arme des Teiles 51 horizontal beweglich geführt sind. In der Mitte enthält der Teil einen ringförmigen Bereich, welcher mittels Schrauben 53 mit dem Stein 5 verbunden ist. Wie aus der F i g. 1 hervorgeht, befinden sich zwischen dem TeilPart 50 is also provided with grooves on the side, in which arms of the part 51 are guided horizontally movable. In the middle contains the part an annular area which is connected to the stone 5 by means of screws 53. As from the F i g. 1 are located between the part

wie aus der Fig.2 ersichtlich ist, ist der Teil S« an seinen Gleitflächen mit hydrostatischen Schmier taschen 61, 62 sowie symmetrisch dazu ausgebildeten Schmiertaschen 61' und 62' versehen. Die Schmiertaschen 61 und 62 sind durch Bohrungen 65, 66 mit einer Verbindungsbohrung 67 verbunden, welche in den Kanal 34 des Deckels 31 führt. Die Schmiertaschen 61' und 62' sind durch Bohrungen 65' und 66' ♦o mit Verbindungsbohrungen 67' verbunden, die in den Kanal 35 des Deckels 31 führen. Je nach der Drehrichtung der Maschine sind auf diese Weise die entsprechenden belasteten Schmiertaschen an den Kanal des Deckels 31 angeschlossen, welcher unter Druck steht. So wird eine hydrostatische Schmierung der Führungsanordnung erzielt, wodurch eine minimale Reibung und Abnützung erhalten wird.as can be seen from Fig. 2, the part S is « on its sliding surfaces with hydrostatic lubrication pockets 61, 62 and formed symmetrically thereto Lubricating pockets 61 'and 62' are provided. The lubrication pockets 61 and 62 are through bores 65, 66 with a connecting bore 67, which leads into the channel 34 of the cover 31. The grease pockets 61 'and 62' are connected by bores 65 'and 66' ♦ o with connecting bores 67 ', which in the channel 35 of the cover 31 lead. Depending on the direction of rotation of the machine, the corresponding loaded lubrication pockets connected to the channel of the cover 31, which under Pressure is on. So a hydrostatic lubrication of the guide arrangement is achieved, whereby a minimal Friction and wear and tear is preserved.
Wie aus der F i g. 1 ersichtlich ist, befindet sich die Führungsanordnung mit den Teilen 50, 51 an der Stirnfläche der Kolbenmaschine. Dadurch ist es möglich, dieser äußere Dimensionen zu geben, die im wesentlichen gleich groß sind wie die äußeren Dimensionen der Maschine. Das hat zur Folge, daß die mit den Taschen 61, 62 zusammenwirkenden Lagerflächen in radialer Richtung an einem großen Radius liegen, was zu einer entsprechenden Verringerung der Lagerkräfte führt und eine genaue Führung des Steines 5 ermöglicht.As shown in FIG. 1 can be seen, there is the guide arrangement with the parts 50, 51 on the End face of the piston machine. This makes it possible to give these external dimensions that essentially are the same as the outer dimensions of the machine. As a result, with the pockets 61, 62 cooperating bearing surfaces in the radial direction at a large radius lie, which leads to a corresponding reduction in the bearing forces and precise guidance of the Stone 5 allows.
