Abstract

Eine Dosierpumpe hat eine Kurbelwelle (30, 36; 150), zu deren Antrieb ein bidirektionaler Elektromotor (34; 141) vorgesehen ist. Von einem Exzenter (36; 154) der Kurbelwelle (30, 36; 150) wird eine Membran (50; 160) angetrieben, welche eine Wand eines Pumpenraums (32; 168) bildet und im Betrieb alternierend Saug- und Druckbewegungen ausführt. An diesen Pumpenraum (32; 168) sind eine erste Anschlussleitung (54; 204) und eine zweite Anschlussleitung (56; 170) angeschlossen, von denen die erste Anschlussleitung (54; 204) mit einem ersten, von der Drehstellung der Kurbelwelle (30, 36; 150) gesteuerten Ventil (26; 171) verbunden ist, das dazu ausgebildet ist, die Verbindung zu einem Vorratsbehälter (68; 208) für eine zu dosierende Flüssigkeit, insbesondere eine Harnstofflösung, zu steuern, und von denen die zweite Anschtussteitung (56; 170) mit einem zweiten, von der Drehstellung der Kurbelwelle (30, 36; 150) gesteuerten Ventil (28; 171) verbunden ist, das dazu ausgebildet ist, die Verbindung zu einem Verbraucher (80; 156) zu steuern.
