Piston system, particularly for a hydraulic axial piston machine for sealing piston guided in cylinder, has piston with piston groove, in which piston ring is arranged, where another piton ring is arranged coaxially to former piston ring

摘要

The piston system has a piston (1) with a piston groove (5.1,5.2), in which a piston ring is arranged. Another piton ring is arranged coaxially to the former piston ring. A positive connection is formed between the two piston rings, which prevents a rotation of former piston ring around a common axle and relative to the latter piston ring.
