摘要: The invention relates to a drive pump (1) for viscous mass with suspended solid elements having a determined maximum size, comprising a drive wheel (2) and a driven wheel (3) accommodated in a pump body (4) with an inlet (4.1) and an outlet (4.2) for the viscous mass, wherein when a tooth (2.1) of the drive wheel (2) is in contact with a tooth (3.1) of the driven wheel (3), the minimum distance (5) between the tooth (2.1) of the drive wheel (2) and the adjacent tooth (3.2) of the driven wheel (3) allows accommodation with play of a suspended solid element (12) of the viscous mass, and in case it is a metallic element, it will be blocked, preventing it from coming out of its outlet (4.2).

摘要: Die Erfindung betrifft eine Zahnradpumpe (1) mit einem Gehäuse (2), das eine Kammer (20) aufweist, in welcher zwei miteinander kämmende Zahnräder (9,10) jeweils drehbar gelagert angeordnet sind, wobei das Gehäuse (2) mindestens einen in die Kammer (20) führenden Zulauf (21) sowie mindestens einen aus der Kammer (20) herausführenden Ablauf (22) aufweist. Dabei ist vorgesehen, dass eine die Kammer (20) insbesondere stirnseitig begrenzende Abdeckung (19) zumindest bereichsweise zum Vergrößern des Kammervolumens verlagerbar ist.
