  • the second hollow body of the upper housing part which is inserted in a protruding cylindrical wall section above the intermediate wall, has an eccentric, channel-like outlet opening which runs parallel to the axis and which is directly connected to a cavity in which the closing element of the dispensing valve is arranged and the rest of it is connected to the interior of the bellows via this dispensing valve, while the upper housing part as a whole moves downward relative to the lower housing part in the course of a delivery stroke.
  • Paste dispensers are also already known (US Pat. No. 4,438,871 and DE-OS 30 38 917), in which stopper-like closing elements for the dispensing opening are arranged on elastic membrane walls which are acted upon by the medium to be dispensed in the opening direction during the working stroke.

  • the metering pump according to the invention which was explained in more detail above with the aid of a paste dispenser, can in principle also be used for liquid media. To do this, however, it is necessary to simultaneously output a second medium, i.e. to dispense with the conveyance of a second medium through the second pump chamber 32 and to completely seal the second storage space 93/1 with respect to the connecting channel 92 and the paste storage space 93.

  • the operation of the above-described metering pump 1 differs from the generic, conventional metering pumps, which also have a bellows as a pumping element, essentially in that the closing element of the exhaust valve moves during the working stroke against the direction of exit of the medium and not in the closing direction and that through the closing member 82 immediately closes the outlet opening, so that the paste storage space 93 is hermetically closed in the idle state.
  • the opening movement of the plug-like closing member 82 is generated by the hydraulic overpressure in the paste storage space 93 which occurs during the downward working stroke of the upper housing part 4, which results in a corresponding opening movement of the membrane wall 80 and thus of the closing member 82 to the inside.
  • the closing member 82 is moved back into the closed position by the spring forces that are inherent in the membrane wall 80 and supported by the air compression in the cavity of the guide body 23 and possibly the displacement piston 36, so that a tight closure the outlet opening is created.
