Abstract

Die Erfindung betrifft eine Regeleinrichtung für eine verstellbare Pumpe (6), mit einer einen Verstellzylinder (4) aufweisenden hydraulischen Verstelleinrichtung (5) und einem Regelventil (51), in dem ein Leistungsregler (52) zur Einstellung der Fördermenge sowie ein Druckregler (73) zur Beschränkung des Arbeitsdrucks (A) an einer bestimmten Obergrenze integriert sind, wobei mit der den Verstellzylinder (4) hydraulisch beaufschlagenden Leitung (19, 62) eine gedrosselte Ablaufleitung abzweigt, die zum Rücklauf (9) führt. Aufgabengemäß soll der für eine dynamische Stabilität erforderliche Strömungsverlust verringert werden. Dies wird dadurch erreicht, daß der Strömungsdurchgang der gedrosselten Ablaufleitung (92,89,93,47) mit zunehmendem Ansprechen des Druckreglers (73) geöffnet wird.
