Abstract

Die Erfindung betrifft eine Außenzahnradpumpe mit mindestens zwei in einem Eingriffsbereich miteinander kämmenden Zahnrädern und mit einem Bypasskolben, der einen Druckabbau der angetriebenen Außenzahnradpumpe dahingehend ermöglicht, dass eine überschüssige Fördermenge über einen Bypass von einer Druckseite zu einer Saugseite der angetriebenen Außenzahnradpumpe gelangt. Die Erfindung zeichnet sich dadurch aus, dass der Bypasskolben bei geschlossenem Bypass mit einem geringen Spiel zu den in dem Eingriffsbereich miteinander kämmenden Zahnrädern angeordnet ist.
