Patent ID: 7261075

Claim:
A hydraulic support element for a valve train of an internal combustion engine, comprising a hollow cylindrical housing having a bore in which a pressure piston runs in an axially moveable manner, one end of said piston projecting beyond an edge of the housing and said piston having on said one one end a head for mounting a rocker arm and having a non-return valve on the other end of the piston, a high pressure space for hydraulic medium positioned between the other end of the piston and an opposing base of the housing, said high pressure space capable of being supplied with the hydraulic medium from a storage space situated above the other end of the piston and enclosed by the pressure piston, wherein the one end of the pressure piston which projects beyond the edge of the housing and in at least a portion of the piston which adjoins the one end of the piston is situated within the housing and extends into the vicinity of the non-return valve, comprises synthetic material reinforced with glass fibers or carbon fibers, and wherein a catch projection is arranged on an outer casing of the portion of the pressure piston which is situated within the housing, and the bore has an annular groove in which the catch projection axially moves; and said annular groove is an upper step for the catch projection.
