Abstract

Die Erfindung bezieht sich auf einen Hydraulikantrieb (1) mit einer Mengen- und/oder Druck-Regelung für einen Druckübersetzer einer Hochdruckeinrichtung, bestehend im Wesentlichen aus einem Motorantrieb mit einer Pumpe für ein Druckmittel (10) sowie einer Steuerung.
Um die Arbeitsweise der Hochdruckeinrichtung zu verbessern, ist erfindungsgemäß vorgesehen, dass als Hydraulikantrieb (1) im Wesentlichen eine Konstant-Förderstrom-Pumpe (11), bzw. eine Pumpe (11), welche je Umdrehung ein konstantes Volumen fördert, angetrieben von einem Servomotor (12), verwendet wird, welcher Servomotor (12) niederdruckseitige Mittel (13) und/oder durch hochdruckseitige Mittel (14) elektrisch (15) steuerbar, regelbar und/oder schaltbar ist.
