Abstract

Eine Dosierpumpeinrichtung, insbesondere für ein Heizgerät, umfasst ein wenigstens bereichsweise in eine eine Pumpkammer (16) bereitstellende Aussparung (18) eingreifendes Ventil/Pump-Organ (20), wobei das Ventil/Pump-Organ (20) um eine Achse (A) drehbar ist und in einer ersten Drehstellung eine Verbindung zwischen der Pumpkammer (16) und einem Auslassbereich (38) zulässt und in einer zweiten Drehstellung eine Verbindung zwischen einem Einlassbereich (24) und der Pumpkammer (16) zulässt, und wobei das Ventil/Pump-Organ (20) zum Ermöglichen der Aufnahme von zu förderndem Fluid in der Pumpkammer (16) von dem Einlassbereich (24) und zur Abgabe von zu förderndem Fluid aus der Pumpkammer (16) in den Auslassbereich (38) in Richtung der Achse (A) bewegbar ist.

Figure 00000001
A metering pump device, in particular for a heating device, comprises a valve / pump element (20) which engages at least partially in a recess (18) providing a pump chamber (16), the valve / pump element (20) about an axis (A) is rotatable and allows a connection between the pump chamber (16) and an outlet region (38) in a first rotational position and permits a connection between an inlet region (24) and the pump chamber (16) in a second rotational position, and wherein the valve / pump Organ (20) for enabling the uptake of fluid to be conveyed in the pumping chamber (16) from the inlet region (24) and for dispensing fluid to be conveyed out of the pumping chamber (16) into the outlet region (38) in the direction of the axis (A) is movable.
