Abstract

Zwei Kolben/Zylinder-Anordnungen (3a, 3b) werden im wesentlichen synchron betrieben. Die Zylinder werden dabei durch die Kolben (5a, 5b) in zwei Teilzylinder unterteilt. Je Teilzylinder an den Kolben/Zylinder-Anordnungen (3a, 3b) sind miteinander verbunden. Aus einem Druckzylinder (11) wird Hydraulikmedium bei Betrieb der Kolben/Zylinder-Anordnungen bezüglich der erwähnten Verbindung hin und her gepumpt, wobei der Druck im Speicher (11) bei Vorliegen von Leckage an den Anordnungen mit der Zeit abnimmt. Er wird gemessen (24), mit einem Referenzwert verglichen, und falls er unter diesen abfällt, wird der Speicher (11) durch kurzzeitiges Öffnen des Systems wieder auf SOLL-Druck geladen (12, 14).
