DESCRIPCIONDESCRIPTION
Unidad distribuidoraDistribution unit
La invencion se refiere a una unidad distribuidora de agentes Ifquidos o pastosos con un deposito, en cuyo cuello se ha montado una bomba dosificadora que presenta dos componentes, habiendose empalmado un primer componente cilmdrico hueco de la bomba dosificadora al cuello y presentando una primera valvula de una v^a con un primer cuerpo de valvula en un orificio de admision, donde un segundo componente conformador de un embolo de la bomba dosificadora, provisto de un apendice de accionamiento exterior para una carrera de la bomba dosificadora, se extiende de modo desplazable en el primer componente, y presentando una segunda valvula de una via en un orificio de distribucion alineado con el orificio de admision con un segundo cuerpo de valvula preferiblemente sometido a la accion de un muelle, y donde las dos valvulas de una via abren en la misma direccion, y siendo variable la separacion entre los dos cuerpos de valvula. La primera valvula de una via se designa a continuacion tambien como valvula de admision y la segunda valvula de una via, como valvula de distribucion.The invention relates to a distributor unit of liquid or pasty agents with a reservoir, on whose neck a dosing pump having two components has been mounted, a first hollow cylindrical component of the dosing pump having been connected to the neck and presenting a first valve of a line with a first valve body in an inlet port, where a second forming component of a dosing pump plunger, provided with an external actuation appendix for a dosing pump stroke, extends displaceably in the first component, and presenting a second one-way valve in a distribution orifice aligned with the intake orifice with a second valve body preferably subjected to the action of a spring, and where the two one-way valves open therein direction, and the separation between the two valve bodies being variable. The first one-way valve is also referred to below as the intake valve and the second one-way valve, as the distribution valve.
Vease tambien el documento WO 82/04203 como proximo estado de la tecnica.See also WO 82/04203 as the next state of the art.
A partir del documento FR 10 64 626 se conoce un deposito con una bomba dosificadora para un agente lfquido que no se define mas detalladamente, estando invertido el deposito durante la distribucion. Los dos cuerpos de valvula tienen forma de bolo y se disponen en los dos extremos de una varilla sometida a accion elastica, estando cerrada la segunda valvula en posicion de reposo por el orificio de distribucion y la primera valvula, abierta por el orificio de admision, de manera que la camara de la bomba este rellena de agente. Si se eleva el segundo componente conformador del embolo de la bomba dosificadora, se cierra entonces la primera valvula y se abre la segunda, de modo que pueda vaciarse la porcion de agente contenida en la camara de la bomba.From FR 10 64 626 a tank with a metering pump is known for a liquid agent that is not defined in more detail, the tank being inverted during distribution. The two valve bodies have a bolus shape and are arranged at both ends of a rod subjected to elastic action, the second valve being closed in the rest position by the distribution hole and the first valve, opened by the intake port, so that the pump chamber is filled with agent. If the second forming component of the dosing pump plunger is raised, then the first valve is closed and the second valve is opened, so that the portion of agent contained in the pump chamber can be emptied.
Bajo la accion del muelle de retroceso, el segundo componente conformador del embolo vuelve entonces a la posicion de partida, cerrandose la segunda valvula y abriendose la primera de modo que vuelve a llenarse la camara de la bomba.Under the action of the recoil spring, the second component of the plunger then returns to the starting position, closing the second valve and opening the first one so that the pump chamber is filled again.
La union ngida de los dos cuerpos de valvula da lugar a inexactitudes en la dosificacion, ya que las dos valvulas no son optimamente sincronizables la una con la otra, desempenando un papel las propiedades de fluidez del agente. Aunque la union ngida tiene la ventaja de que, por ejemplo, en caso de inclusion de aire en la camara de la bomba, la valvula de distribucion tambien se abre entonces fiablemente, cuando la presion existente en la camara de la bomba no sea suficiente para ello.The binding of the two valve bodies leads to inaccuracies in the dosage, since the two valves are not optimally synchronized with each other, the fluidity properties of the agent playing a role. Although the nigged union has the advantage that, for example, in case of inclusion of air in the pump chamber, the distribution valve also opens reliably, when the pressure in the pump chamber is not sufficient to it.
La invencion es ha fijado, pues, la mision de crear una unidad de distribucion constituida por el deposito y la bomba dosificadora conectada con el, con la que se eviten, incluso en un caso de avena, posiciones de valvula causantes de inexactitudes en la dosificacion. Se consigue esto de modo que el primer cuerpo de valvula, dispuesto en el orificio de admision, se configure como limitador de orificio para el segundo cuerpo de valvula dispuesto en el orificio de distribucion situado opuestamente.The invention is therefore set the mission of creating a distribution unit consisting of the tank and the metering pump connected to it, with which, even in an oatmeal case, valve positions causing inaccuracies in the dosage are avoided . This is achieved so that the first valve body, disposed in the intake port, is configured as a hole limiter for the second valve body disposed in the oppositely located distribution hole.
De ese modo, los dos cuerpos de valvula trabajan sin influenciarse mutuamente durante una parte esencial de la carrera de la bomba, y solo se da lugar en caso de avena a un acoplamiento directo entre los dos cuerpos de valvula antes del final de la carrera, si el segundo cuerpo de valvula se encuentra en la posicion de cierre, acoplamiento que abre forzadamente la valvula de distribucion. El aire comprimido encerrado en la camara de la bomba puede salir por ello de la bomba dosificadora. Esto resulta ventajoso precisamente en un primer accionamiento. El acoplamiento de las dos valvulas asegura tambien que, en caso de una valvula de distribucion reseca, como puede ocurrir en el caso de una parada de larga duracion, se abra mecanicamente el segundo cuerpo de valvula. La fuerza de cierre de la valvula de admision corresponde, en este caso, a la necesaria fuerza de apertura de la valvula de distribucion.Thus, the two valve bodies work without influencing each other during an essential part of the pump stroke, and only a direct coupling between the two valve bodies occurs before the end of the stroke, in case of oatmeal, if the second valve body is in the closed position, coupling that forcefully opens the distribution valve. The compressed air enclosed in the pump chamber can therefore leave the metering pump. This is advantageous precisely in a first drive. The coupling of the two valves also ensures that, in the case of a dry distribution valve, as can occur in the case of a long-term shutdown, the second valve body is mechanically opened. The closing force of the intake valve corresponds, in this case, to the necessary opening force of the distribution valve.
Se preve ademas preferiblemente que el segundo cuerpo de valvula presente un vastago penetrante axialmente en la bomba dosificadora, cuyo extremo libre este a distancia de la valvula de distribucion.It is also preferably provided that the second valve body has an axially penetrating rod in the metering pump, the free end of which is at a distance from the distribution valve.
En el vastago puede configurarse un apoyo para el muelle, que fuerza al segundo cuerpo de valvula a la posicion de cierre de modo que la valvula de distribucion quede estanca y el agente no gotee despues.In the rod a spring support can be configured, which forces the second valve body to the closed position so that the distribution valve is sealed and the agent does not drip afterwards.

La unidad distribuidora, en especial para utilizacion invertida en un dispensador para distribuir un agente lfquido o pastoso, comprende deposito 1 ngido, ventilable con una bomba 5 dosificadora dispuesta en su cuello 2, que como muestra la figura 1 esta cubierta hasta su utilizacion por una caperuza 3. La bomba 5 dosificadora comprende dos componentes 11, 16 principales, de los que el primer componente 11 se ha dispuesto en el cuello del deposito, en especial, de modo inseparablemente encolado o soldado, si el deposito 1 y la bomba 5 dosificadora estan hechos de un plastico. Una unidad distribuidora semejante se sustituye por una llena tras su vaciado. Aunque tambien podna pensarse montar la bomba 5 dosificadora separablemente en el deposito 1 de modo que la unidad distribuidora pueda volver a rellenarse y utilizarse.The distribution unit, especially for inverted use in a dispenser for distributing a liquid or pasty agent, comprises a nested tank 1, ventilatable with a metering pump 5 arranged in its neck 2, which as shown in Figure 1 is covered until it is used by a cap 3. The dosing pump 5 comprises two main components 11, 16, of which the first component 11 has been arranged in the neck of the tank, especially inseparably glued or welded, if the tank 1 and the dosing pump 5 They are made of a plastic. A similar distribution unit is replaced by a full one after emptying. Although it could also be thought to mount the dosing pump 5 separably in the tank 1 so that the distributor unit can be refilled and used again.
El primer componente 11 de la bomba 5 dosificadora se ha configurado de forma cilmdrica y hueca y se ha previsto un orificio de admision en la zona de union con el deposito, al que se ha asociado una valvula de aspiracion en forma de una primera valvula 6 de una via. Para la disposicion invertida mostrada en las figuras, se ha configurado en forma de bolo el primer cuerpo 7 de valvula previsto en la primera valvula de una via y se ha mantenido suelto en una jaula 12 de valvula, que comprende varios nervios con resaltos extremos salientes hacia adentro. El asiento de valvula es conico. Debido a la fuerza de la gravedad, la primera valvula 6 de una via esta abierta en la posicion de reposo mostrada en la figura 2. Otras valvulas de admision adecuadas son, por ejemplo, valvulas de mariposa, valvulas de paraguas, o valvulas de pico.The first component 11 of the metering pump 5 has been cylindrical and hollow configured and an intake port is provided in the area of union with the reservoir, to which a suction valve in the form of a first valve 6 has been associated One way. For the inverted arrangement shown in the figures, the first valve body 7 provided in the first one-way valve has been configured in a bolus shape and has been kept loose in a valve cage 12, comprising several ribs with protruding projecting ends into. The valve seat is conical. Due to the force of gravity, the first valve 6 of a track is open in the resting position shown in Figure 2. Other suitable intake valves are, for example, butterfly valves, umbrella valves, or peak valves. .
El segundo componente 16 de la valvula 5 dosificadora forma su embolo y se ha dispuesto de forma desplazable contra un muelle 21 en el primer componente 11 cilmdrico hueco de modo que la camara 20 de transporte de la bomba dosificadora pueda modificarse. Enfrentadamente al orificio de admision del primer componente 11, se ha previsto un orificio de distribucion en el segundo componente 16, al que esta asociada una valvula de distribucion en forma de una segunda valvula 8 de una via igualmente dirigida o sea que se abre hacia fuera. La segunda valvula 8 de una via tiene un cuerpo 9 de valvula que se ensancha conicamente y que posee un vastago 10 que discurre axialmente en la camara 20 de transporte. El vastago termina a una distancia a variable del primer cuerpo 7 de valvula, que es menor que la carrera h de la bomba 5 dosificadora. El vastago 10 presenta un reborde anular, y un muelle 22 de cierre se encuentra empotrado entre el reborde anular y la cara interior del asiento de valvula en el segundo componente 16. En la posicion de reposo mostrada en la figura 2, la segunda valvula 8 de una via esta por ello cerrada hermeticamente. El muelle 22 de cierre determina la presion del orificio de la bomba 5 dosificadora.The second component 16 of the metering valve 5 forms its plunger and is movably arranged against a spring 21 in the first hollow cylindrical component 11 so that the transport chamber 20 of the metering pump can be modified. Facing the inlet port of the first component 11, a distribution port is provided in the second component 16, to which a distribution valve is associated in the form of a second valve 8 of an equally directed way or that opens outwards. . The second one-way valve 8 has a valve body 9 that widens conically and has a rod 10 that runs axially in the transport chamber 20. The rod ends at a variable distance from the first valve body 7, which is smaller than the stroke h of the metering pump 5. The rod 10 has an annular flange, and a closing spring 22 is embedded between the annular flange and the inner face of the valve seat in the second component 16. In the rest position shown in Figure 2, the second valve 8 One way is therefore tightly closed. The closing spring 22 determines the orifice pressure of the metering pump 5.
La camara 20 de transporte se reduce elevando el segundo componente 16, que conforma el embolo. El mecanismo empleado para ello no es objeto de la invencion, donde en la figura 2 solo se ha dibujado de trazos un manguito 25 de arrastre, previsto en un dispensador en la utilizacion invertida, que encaja en un apendice 17 de accionamiento del segundo componente 16 alrededor de la segunda valvula 8 de una via. Por debajo del orificio de distribucion puede preverse todavfa un regulador 18 de chorro o similar dado el caso intercambiable, en forma de disco para controlar el caudal o bien la pulverizacion del medio emergente.The transport chamber 20 is reduced by raising the second component 16, which forms the plunger. The mechanism used for this is not the object of the invention, where in figure 2 only a drag sleeve 25, provided in a dispenser in the inverted use, which fits into a drive appendix 17 of the second component 16 has been drawn in strokes. around the second valve 8 of a way. A jet regulator 18 or the like can be provided below the distribution orifice, where appropriate, in the form of a disk to control the flow rate or the spraying of the emerging medium.
Si el manguito 25 de arrastre se eleva a partir de la posicion de la figura 2, entonces se expulsa agente encerrado en la camara 20 de transporte mediante la segunda valvula 8 de una via a traves del orificio de distribucion, ya que la primera valvula 6 de una via bloquea el camino al deposito 1. Al final de la carrera, el vastago 10 del segundo cuerpo 9 de valvula queda junto al primer cuerpo 7 de valvula. Si se vuelve a liberar la bomba 5 dosificadora en la posicion comprimida que se muestra en la figura 3, se amplfa entonces la camara 20 de transporte por accion del muelle 21, donde al comienzo de la carrera de retorno se aspira de vuelta a la camara 20 de transporte un resto sobrante de agente en la zona de la valvula a traves de la valvula 8 de una via aun abierta, debido al apoyo del vastago 10 en el cuerpo 7 de valvula, de modo que se evite un goteo ulterior. Despues de este corto instante, se aleja el vastago 10 del primer cuerpo 7 de valvula con la carrera de vuelta progresiva de modo que, por un lado, pueda cerrarse la segunda valvula 8 de una via y, por otro, pueda abrirse la primera valvula 6 de una via. En adelante, se aspirara el agente del deposito 1 hasta que la carrera de retorno este acabada y se vuela a alcanzar la posicion de reposo segun la figura 2.If the drag sleeve 25 rises from the position of Fig. 2, then agent locked in the transport chamber 20 is ejected through the second valve 8 of a path through the distribution hole, since the first valve 6 One way blocks the path to the tank 1. At the end of the race, the rod 10 of the second valve body 9 is adjacent to the first valve body 7. If the metering pump 5 is released again in the compressed position shown in figure 3, then the transport chamber 20 is extended by the action of the spring 21, where at the beginning of the return stroke it is sucked back into the chamber 20, a surplus of agent remains in the area of the valve through the valve 8 of a still open path, due to the support of the rod 10 in the valve body 7, so as to avoid further dripping. After this short moment, the rod 10 of the first valve body 7 moves away with the progressive return stroke so that, on the one hand, the second valve 8 can be closed one way and, on the other, the first valve can be opened 6 one way. Thereafter, the agent from the reservoir 1 will be aspirated until the return stroke is finished and the rest position is flown according to figure 2.
El apoyo del vastago 10 en el primer cuerpo 7 de valvula ayuda a subsanar o evitar avenas de funcionamiento, que se podnan producir de que el segundo cuerpo 9 de valvula, en especial tambien por la accion del muelle 22 de cierre, quede atascado en el orificio de distribucion. Estas avenas de funcionamiento dependen del tipo y la consistencia del agente contenido y de la inclusion de aire simultanea en la camara 20 de transporte, sobre todo en la primera utilizacion, poco antes del avance del contenido o tras largo periodo de no utilizacion por adherencia del segundo cuerpo 9 de valvula al orificio de evacuacion. La elevacion del segundo componente 16 que forma el embolo vaciana solo entonces en un caso semejante la camara 20 de transporte si el aire encerrado pudiese comprimirse de tal modo que la compresion bastase para liberar el segundo cuerpo 9 de valvula adherido. Si la proporcion de aire fuese tan grande, entonces sena incluso imaginable que el segundo cuerpo 9 de valvula permaneciese en su asiento de valvula, y la bomba dosificadora sena inutil, ya que cada carrera solo comprime el aire y cada carrera de retorno lo vuelve a descomprimir pero no lo desaloja.The support of the rod 10 in the first valve body 7 helps to correct or avoid operating avenues, which can be produced so that the second valve body 9, especially also by the action of the closing spring 22, is stuck in the distribution hole. These operating oats depend on the type and consistency of the contained agent and the inclusion of simultaneous air in the transport chamber 20, especially in the first use, shortly before the advance of the content or after a long period of non-use due to adhesion of the second valve body 9 to the evacuation hole. The elevation of the second component 16 that forms the emptying pin then only in a similar case the transport chamber 20 if the enclosed air could be compressed in such a way that the compression was sufficient to release the second valve body 9 attached. If the air ratio were so large, then it would even be imaginable that the second valve body 9 would remain in its valve seat, and the dosing pump would be useless, since each stroke only compresses the air and each return stroke returns to Unzip but not evict.
Un caso de avena de este genero causado, sobre todo, por inclusion de aire puede observarse en la figura 4. Al comienzo de la carrera se cierra la primera valvula 6 de un via, y el primer cuerpo 7 de valvula es comprimido en el asiento de valvula, mientras que el segundo cuerpo 9 de valvula, que ya se ha sometido ademas efectivamente a la accion del muelle 22 de compresion, no se ha movido hacia abajo, de modo que la segunda valvula 8 de una via 5 permanece igualmente cerrada. Con elevacion adicional, puede aumentarse suficientemente la compresion en la camara 20 de transporte, y se abre la segunda valvula 8 de una via, despues de lo cual discurren mas procesos de dosificacion del modo deseado. Aunque si esto no bastase, entonces el vastago 10 del segundo cuerpo 9 de valvula chocana en el primer cuerpo 7 de valvula tras unos dos tercios de la carera h - el cuerpo 9 de valvula queda entonces mas elevado y cercano a la primera valvula 6 de una via, que si se hubiese abierto -. Ese momento se ha 10 representado en la figura 5. La carrera h-a residual restante traslada el cuerpo 9 de valvula forzadamente a la posicion abierta segun la figura 3 de manera que la bomba 5 dosificadora vuelva a estar operativa y permanezca asf, y se distribuya una porcion completa con el siguiente accionamiento.A case of oats of this genus caused, above all, by inclusion of air can be seen in Figure 4. At the beginning of the race the first valve 6 of a track is closed, and the first valve body 7 is compressed in the seat of the valve, while the second valve body 9, which has already been effectively subjected to the action of the compression spring 22, has not moved downward, so that the second valve 8 of a track 5 remains equally closed. With additional elevation, the compression in the transport chamber 20 can be sufficiently increased, and the second valve 8 is opened one way, after which more dosing processes run as desired. Even if this is not enough, then the rod 10 of the second body 9 of the chocana valve in the first valve body 7 after about two thirds of the race h - the valve body 9 is then higher and closer to the first valve 6 of one way, that if it had opened -. That moment has been represented in Figure 5. The remaining residual stroke moves the valve body 9 forcibly into the open position according to Figure 3 so that the dosing pump 5 becomes operational again and remains so, and a distribution is distributed. Full portion with the following drive.
Para que pueda afluir aire adentro de un deposito 1, que no deba ser comprimido por la presion de aire exterior, 15 cuando el agente es aspirado a la camara 20 de transporte, se ha previsto un canal 14 de ventilacion en la zona del primer componente 11 de la bomba 5 dosificadora fijado en el cuello 2, que se extiende por el deposito y que esta provisto de otra valvula de una via mas, en especial, una valvula de pico de pato.So that air can flow into a reservoir 1, which should not be compressed by the outside air pressure, 15 when the agent is sucked into the transport chamber 20, a ventilation channel 14 is provided in the area of the first component 11 of the metering pump 5 fixed in the neck 2, which extends through the tank and which is provided with another one-way valve, in particular, a duckbill valve.
El muelle 21 para la posicion de retorno del segundo componente 16 de la bomba 5 dosificadora puede suprimirse, 20 cuando el mecanismo de accionamiento para la bomba 5 dosificadora no descrito con mayor detalle, del cual se ha dibujado de trazos el manguito 25 de arrastre en la figura 2, presente un muelle de recuperacion o similar, y el manguito 25 de arrastre conduzca forzadamente el talon 17 de accionamiento en las dos direcciones.The spring 21 for the return position of the second component 16 of the metering pump 5 can be suppressed, 20 when the drive mechanism for the metering pump 5 not described in greater detail, of which the drag sleeve 25 is drawn in strokes. 2 shows a recovery spring or the like, and the drag sleeve 25 forcibly drives the drive heel 17 in the two directions.
