Adjustment device for an axial piston machine and hydraulic machine having such an adjustment device

Abstract

An adjustment device for a pivoting cradle of a hydraulic machine, in particular of an axial piston machine, is disclosed. Said adjustment device has an actuating piston to which pressure medium for pivoting the pivoting cradle about a pivoting axis is applied via an actuating pressure space. In order to control the feeding in of pressure medium and the relieving of the actuating pressure space, a control valve is provided. Said control valve has a control piston configured to be adjusted by an electric actuator, wherein the electric actuator is controlled by a control device. In this context, the control device controls the electric actuator as a function of a control difference formed from a setpoint pivoting angle and an actual pivoting angle of the pivoting cradle. The actual pivoting angle of the pivoting cradle is fed back electrically to the control device here.
