Abstract

A displacement volume setting device of a hydrostatic variable displacement axial piston unit includes an input device for providing a displacement command. Displacement volume adjusting means set the tilt angle of a displacement element according to the displacement command. A linkage element has an input coupling element connected to the input device, an output coupling element connected to the displacement volume adjusting means, and a connecting element. The input coupling element and the output coupling element are connected by the connecting element which is elastically deformable if a force resulting from the high pressure level present at the hydrostatic axial piston unit and acting on the output coupling element exceeds a predetermined threshold value. Also disclosed is a hydrostatic variable displacement axial piston unit.
