Hydraulic play element for internal combustion engine, has axially movable pressure piston combined together with cylindrical housing

摘要

The hydraulic play adjustment element (1) has a cylindrical housing (2) with an axially movable piston (3). The high-pressure area (6), which is responsible for the hydraulic play, lies between front sides (4,5) of the piston and the housing. Height (H-f)of the Chamfer (16) provided between the front face (4) and passage area of the outer casing (10) is greater/equal to height (H r) of ring extension.
