摘要:
Conventional wiper arrangements with cut rings suffer from unavoidable leakage and, in particular in an embodiment as metallic wiper ring with a sharp wiping edge, scratch on the surface of the piston rod which can be damaged in this manner. In order to eliminate these problems, a wiper arrangement with a wiper ring 2 which is split in the circumferential direction and an L-shaped cover ring 3 which is split in the circumferential direction is proposed, wherein the splitting points 16, 15 of the cover ring 3 and the wiper ring 2 are arranged offset to each other in the circumferential direction, and the wiper ring 2 is arranged abutting axially as well as radially in the recess 4 of the L-shaped cover ring 3, and the radially inner circumferential surfaces 6, 7 of the wiper ring 2 and the cover ring 3 form a common radially inner wiping surface 10.
