Abstract

Die Offenbarung betrifft eine Verstellpumpe mit einem zwischen einem Kompensationsdruck und einem Regeldruck angeordneten Hubring, der über die Drücke verstellbar ist, um die Verstellpumpe auf oder ab zu regeln, und mit einer Regelventileinrichtung, die zwischen einen Verbraucher und den vorzugsweise vorgespannten Hubring geschaltet ist. Die Offenbarung zeichnet sich dadurch aus, dass die Regelventileinrichtung als Ablaufregelung ausgeführt ist.
