Hydraulic adjusting device with feedback and hydrostatic an adjustable axial piston machine in a swash plate design

摘要

Disclosed is a hydraulic cylinder with an adjusting piston, in which a control valve is integrated, which via a pilot valve and via a feedback of the path of the adjusting piston can be controlled. The pilot valve is a pressure-reducing valve, the valve body by means of a magnet arrangement, starting from a central basic position can be adjusted bidirectionally. In this way, the adjusting piston a basic position and can be moved from this starting bidirectionally.Furthermore, a hydrostatic axial piston machine is disclosed, the swash plate with such an adjusting device can be pivoted.
