| 摘要 | A sealing ring, in particular for a hydraulic piston pump, for sealing a pressure chamber which is filled with a fluid is disclosed. A sealing lip having a contour contacts a sealing surface and is movable relative thereto. The contour of the sealing lip is adapted according to the speed of the sealing lip relative to the sealing surface, such that a defined leakage of the fluid out of the pressure chamber is adjusted. | ||

| 主权项 | 1. A sealing ring for a hydraulic piston pump for sealing off a pressure space which is filled with a fluid, comprising: a sealing lip configured with a contour to bear against a sealing surface, the contour defining a first curved portion, an opposite second curved portion, and a parallel portion extending from the first curved portion to the second curved portion, the parallel portion running essentially parallel to the sealing surface, and the sealing lip being movable in relation to the sealing surface, wherein the contour of the sealing lip is adapted to the speed of the sealing lip in relation to the sealing surface so that a defined leakage of the fluid out of the pressure space is set. | ||
