Abstract

Bei einer Zweizylinder-Dickstoffpumpe mit Kolben­ speicher, welcher während der Dickstoffförderung mit den Förderzylindern gefüllt und zwischen den Hüben der Förderkolben in die Förderleitung zur Verminderung des Druckabfalls und der Fehlförder­ menge in der Förderleitung durch den druckmittelge­ steuerten Speicherkolben entleert wird, ist erfin­ dungsgemäß vorgesehen, daß zur Druckmittelsteuerung (2) des Speicherkolbens (10) ein beidseitig hydrau­ lisch beaufschlagbarer Arbeitskolben (8) dient, der mit den Förderzylindern gesteuert ist und dessen Endlagen mit den Endlagen des Speicherkolbens (10) bei vollständig entleertem und bei gefülltem Speicher­ zylinder (4) am Speicherantriebszylinder (7) festge­ legt sind.
