Abstract

Eine Dosierpumpeinrichtung für ein Fahrzeugheizgerät umfasst eine Einlasskammer (40), eine Auslasskammer (54), eine erste Ventilanordnung (66) zwischen der Einlasskammer (40) und der Auslasskammer (54), welche einen Fluidaustausch im Wesentlichen nur von der Einlasskammer (40) zur Auslasskammer (54) zulässt, ein Verdrängungskolbenelement (12), welches in einer ersten Kolbenstellung das Volumen der Einlasskammer (40) minimiert und in einer zweiten Kolbenstellung das Volumen der Auslasskammer (54) minimiert.

A metering pump device for a vehicle heater comprises an inlet chamber (40), an outlet chamber (54), a first valve arrangement (66) between the inlet chamber (40) and the outlet chamber (54), which substantially only exchange fluid from the inlet chamber (40) Outlet chamber (54) allows a displacement piston member (12) which in a first piston position minimizes the volume of the inlet chamber (40) and in a second piston position minimizes the volume of the outlet chamber (54).
