Definitions

  • the invention relates to an output device with a thrust piston pump for discharging media, in particular liquids, from a storage vessel or the like.
  • the pump In the top position and, conversely, in the upside-down position, the pump of which comprises a cylinder and, to delimit a pump chamber, a piston unit which can be moved by hand and an outlet channel and suction channels for the top and the top position, of which the suction channel for the top position is provided with a valve arrangement in the manner of a check valve that closes when there is overpressure in the pump chamber and in the top position when there is underpressure in the pump chamber, the two oppositely arranged valve seats each for the installation of one movable valve body, for example a ball.
  • An atomizer has become known (DE-PS 28 18 560), in which axially one behind the other in the intake duct two separate intake valves with separate valve bodies are provided.
  • one of the suction valves is used both in the top position and in the top position to close the suction channel during the pumping stroke, i.e. when there is an overpressure in the pump chamber, and the other suction valve is provided only in the head position under the weight force acting on the associated valve body during the return stroke of the pump piston to close this suction channel so that a negative pressure builds up in the pump chamber and is sucked in towards the end of the return stroke only via a separate suction channel medium provided exclusively for the head position.
  • the valve body of the first-mentioned suction valve In order to ensure that the medium is only discharged through the outlet channel and not back into the storage vessel during the subsequent pumping stroke, the valve body of the first-mentioned suction valve must be brought into the closed position against the weight of the medium by the flow of a portion of the medium displaced from the pump chamber . Regardless of the flow direction in which the valve bodies of the two exhaust valves are arranged one behind the other, the second exhaust valve interferes with this process due to the flow resistances emanating from it, thereby preventing the valve body of the first exhaust valve from moving quickly or immediately into the closed position, which leads to deviations with regard to the amount of medium discharged during each pump stroke, that is to say inaccurate metering.
  • the arrangement of two separate valve bodies is also complex and takes up additional space.
  • the invention has for its object to an output device of the type mentioned, in particular a double-acting valve assembly in the manner described create, which ensures a faster response in the respective operating situation, especially in the head position with a simplified design.
  • valve seats are arranged at the two ends of a valve chamber receiving the valve body, which preferably has continuously constant internal cross sections between the two valve seats, so that the valve body, for example with an approximately axially aligned arrangement of the Valve seats can be kept practically on a straight trajectory.
  • valve seat which is farther from the pump piston is formed by an insert body, in particular in the center axis of the pump piston, which is inserted into the end of an intake port of a cylinder housing forming the cylinder.
  • This insert body is much easier than one from the pump chamber Assemble the insert body to be assembled and is suitable for additionally serving as a plug-in element for receiving an intake hose or the like to be attached in the manner of a riser pipe.
  • valve seat closer to the pump piston, i.e. the valve seat connected directly to the pump chamber, in such a way that it delimits a valve opening which, in the manner of a baffle jet nozzle, preferably narrowed in the direction of the valve body, in the direction is directed to the opposite valve seat against the valve body.
  • a particularly advantageous embodiment, in particular an output device of the type described, is that an outlet valve mechanically opened towards the end of the pump stroke is arranged in the outlet channel, the outlet valve body of which can be moved between the closed and the open position with an actuating head of the pump opposite the valve seat in the open position is movable.
  • This outlet valve serves to open the outlet channel only when a relatively high pressure is built up in the pump chamber, so that then the medium is discharged suddenly, which is particularly advantageous if the medium is to be atomized during discharge;
  • the opening time of the exhaust valve is to be controlled much more precisely if it is not via an intermediate piston, that is to say influenced by the pressure in the pump chamber.
  • valve seat of the outlet valve is formed by a sleeve-shaped piston sleeve forming the pump piston and penetrated by the outlet channel
  • the outlet valve body can be displaced in a simple manner with a valve stem, for example, it can be slidably mounted on the inner circumferential surface of the piston sleeve, in order to achieve favorable spatial conditions for the valve stem expediently on the outlet side of the closing surface of the valve body.
  • the pump piston In order to be able to simply fix the pump piston against or at the end of the pump stroke in relation to the cylinder, the pump piston is on End of the pump stroke, in particular limited by an inner shoulder located at the end of the piston track.
  • the actuating head, including the outlet valve body, is to be kept in this piston end position in relation to the pump piston in the valve-open position of the outlet valve.
  • the safe and immediate closing of the exhaust valve at the beginning or before the return stroke of the pump piston can be achieved in a very simple manner by arranging a return spring for the piston unit as a closing spring for the exhaust valve and preferably on the piston unit exclusively via the exhaust valve. Valve body is supported.
  • the actuating head is mounted directly on the piston unit, in particular on a piston neck forming the outer end of the piston sleeve and slidably receiving the valve stem of the exhaust valve, so that the piston neck is thus slidably guided both on the inner circumference and on the outer circumference relative to the actuating head is and can therefore be made very thin-walled without the risk of compression.
  • the actuating head receives the piston neck in a sliding sleeve, the actuating head, for example by means of an annular collar engaging in an annular groove, expediently between two end positions both in the direction of the pump stroke and in the direction of the return stroke, which are approximately the closed position and the open position of the Exhaust valves correspond to the valve seat of the exhaust valve or against the piston neck is limited.
  • the actuating head for driving the outlet valve body has an inner stamp which preferably abuts the outer end face of the valve stem and delimits a section of the outlet channel lying in a ring in the actuating head in the center. This also ensures very simple assembly. However, it is also conceivable to design the actuating head in one piece with the outlet valve body, for example in such a way that the inner punch mentioned merges in one piece into the valve stem.
  • an output device 1 which is to be attached to the neck 3 of a storage vessel 2 or the like, has a pump 4 designed as a thrust piston pump, which is protruding into or through the neck 3 with a fastening cap 5, that the storage vessel 2 is tightly closed.
