摘要：The invention relates to a device for adjusting the final control element for thedisplacement volume of a hydrostatic machine, comprising a shaft, which is linked to thefinal control element and which is rotatably mounted about an axis of rotation, arestoring arrangement extending transversely to the shaft and being in engagementtherewith, which restoring arrangement, when the shaft is in the zero position, occupies acorresponding zero position and can be moved therefrom by rotating the shaft out of itszero position against a restoring force. In order to reduce construction cost and effortand to ensure repeatedly accurate setting of the hydrostatic machine to the zero-displacement volume, the shaft (1, 12) has a bearing surface (30) which contains the axis ofrotation (17) of the shaft or is parallel thereto, and the restoring arrangement has asingle restoring element (13), which is loaded by a force in the direction of the zeroposition and which, in its zero position, bears with at least one contact region (37, 38) eachon the bearing surface (30) on both sides of a plane (E) intersecting said bearing surfaceperpendicularly and containing the axis of rotation (17) of the shaft, and which holds theshaft (1, 12) in its zero position, one of the two contact regions (37 or 38, respectively)
moving away from the bearing surface (30) upon rotation of the shaft (1, 12) out of itszero position.
