A hydraulic position control arrangement with a base body which is rotatably supported on a shaft that includes a hydraulic fluid passage for the admission of hydraulic fluid to an operating chamber which is delimited by the base body and an annular piston which is axially movably supported by the base body, includes an annular sealing element disposed in the base body and seated on the shaft and a leakage return path which extends from the area outside the shaft to the operating chamber through the sealing element. The shaft has at least two axial sections with different outside diameters with the sealing element being seated on the axial shaft section of smaller diameter. The sealing element has a seal lip which abuts the outside of the shaft and is axially supported by a support ring which is provided in the base body.
A hydraulic position control arrangement comprising a base body (2) rotatably supported on a shaft (3) which includes a hydraulic channel (8) for the admission of hydraulic fluid to an operating chamber (7) which is delimited by the base body (2) and an annular piston (4) which is axially adjustably supported on the base body (2), an annular seal element (13) disposed on the shaft (3) within the base body (2) and with a leakage return path extending from the outside area of the shaft to the operating chamber (7), wherein the leakage return path extends through the annular seal element (13) and the shaft (3) has at least two axial sections (3a, 3b) of different outside diameters and the annular seal element (13) is seated on the axial section (3b) of smaller diameter, characterized by,
