Abstract

Es wird eine mit mehreren Plungern arbeitende Pumpe beschrieben, wobei die Plunger vorzugsweise über eine Exzentereinheit betätigt werden und bezogen auf das jeweili­ ge Fördervolumen anstelle weniger vergleichsweise großer Plunger mehrere kleine Plunger benutzt und demgemäß bei vergleichsweise hoher Antriebsdrehzahl mit einer Vielzahl kleiner Volumenverdrängerungen gearbeitet wird. Dabei ist der Saugraum im Pumpenkörper mitting angeordnet und die in einem gemeinsamen, ringförmig ausgebildeten Druck­ raum mündenden Hochdruckauslässe der Pumpkammern verlaufen zumindest im wesentlichen radial. It becomes a pump with multiple plungers described, the plungers preferably via a Eccentric unit are operated and related to the respective funding volume instead of less comparatively large Plunger uses several small plungers and accordingly comparatively high drive speed with a variety small volume displacements is worked. It is the suction chamber in the middle of the pump body and the in a common, ring-shaped print high-pressure outlets of the pumping chambers opening into the room run at least essentially radially.
