Abstract

Die für eine Flüssigkeitsdosierpumpe bestimmte Antriebs­ vorrichtung besteht im wesentlichen aus einem motorisch angetriebenen Exzenter (10) und einem durch den Exzenter entgegen der Kraft einer Rückholfeder (12) verschieb­ baren Pumpenstößel (14). Zwischen Motorwelle (24′) und Exzenter (10) ist ein Getriebe (28,28′) mit variablem Unter- und Übersetzungsverhältnis in Abhängigkeit vom Drehwinkel der Motorwelle (24′) angeordnet. Mit diesen einfachen kinematischen Vorkehrungen wird eine Verbesse­ rung des Gesamtwirkungsgrads und damit bei gegebener Pumpleistung eine Reduzierung der Nennleistung des ver­ wendeten Antriebsmotors erzielt. The drive designed for a liquid metering pump device consists essentially of a motor driven eccentric (10) and one through the eccentric move against the force of a return spring (12) pump plunger (14). Between the motor shaft (24 ') and Eccentric (10) is a gear (28,28 ') with variable Ratio and ratio depending on Angle of rotation of the motor shaft (24 ') arranged. With these simple kinematic precautions will be an improvement of the overall efficiency and thus for a given Pump power a reduction in the nominal power of the ver achieved drive motor achieved.
