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.
