Abstract

Pumpeneinrichtung für Pulver, insbesondere für Beschichtungspulver, und Pulverbeschichtungseinrichtung. Es ist eine Zeitsteuereinrichtung (74) vorgesehen, durch welche in Abhängigkeit von der seit einem vorbestimmten Betriebszeitpunkt vergangenen vorbestimmten Verzögerungszeitdauer Druckgas in eine Dosierkammer eingelassen und damit eine bis zum Ende der Verzögerungszeitdauer in die Dosierkammer eingebrachte Pulvermenge aus der Dosierkammer ausgestoßen wird.

Pump device for powder, in particular for coating powder, and powder coating device. A timing device (74) is provided, through which pressurized gas is introduced into a metering chamber as a function of the predetermined delay time that has elapsed since a predetermined operating time and thus a quantity of powder introduced into the metering chamber until the end of the delay period is expelled from the metering chamber.
