Abstract

Elektrohydraulischer Verstärker mit einem elektromechanischen Wandler (2) und einer an eine Druckmittelversorgung (13) angeschlossenen, einen Zylinder (8) und einen darin längs der Arbeitsachse (5) verschiebbaren Kolben (9) aufweisenden hydromechanischen Leistungsstufe (10), wobei der elektromechanische Wandler auf einen der hydromechanischen Leistungsstufe zugeordneten, zumindest teilweise im Inneren des Kolbens (9) angeordneten, in einer Führungsbohrung längs der Arbeitsachse verschiebbar geführten Steuerschieber (23) wirkt, der zwei erste Steuerkanten (38a, 38b) aufweist, die zur Ausbildung einer hydraulischen Folgeregelung mit korrespondierenden, an der Führungsbohrung vorgesehenen zweiten Steuerkanten (39a, 39b) zusammenwirken, wobei die Führungsbohrung zweiteilig mit einem zylinderfesten ersten Abschnitt (25) und einem längs der Arbeitsachse (5) lageveränderbaren zweiten Abschnitt (27), der die zweiten Steuerkanten (39a, 39b) aufweist, ausgeführt ist.
