1 ist oben eine Dichtplatte 3 aufgesetzt, die sich auf der Halterung 2 abstützt und einen
Druckluftanschluß 4 aufweist, mit dem der Kartuschenkolben 5 pneumatisch
beaufschlagbar ist. Weiterhin ist in der Dichtplatte 3 ein Sensor 6 angeordnet, der als
Ultraschallsensor ausgebildet sein kann und die jeweilige Stellung des Kartuschenkolbens
5 in der Kartusche 1 mißt und das Ergebnis einer Steuereinrichtung zuleitet.A
Am unteren Ende der Kartusche 1 ist ein Kartuschenventil 7 vorgesehen, das als Hubventil
ausgebildet sein kann. Hierzu ist im unteren Teil der Halterung 2 eine Hubeinrichtung 8
