Hydraulic support unit for lever-like cam follower of valve gear, has pressure piston designed as one-piece, and deflecting unit represented as star- shaped or wave-like sleeve and lying with its head circle at inner shell of piston

摘要

The unit has a high pressure area formed between a ring bar (9) and a base of a jar-like housing, and a pressure piston (6) with an inlet (13) for hydraulic medium within the housing. The inlet stays in fluid connection with an outlet in the housing, where the piston is designed as one-piece. A deflecting unit (15) is represented as a star- shaped or wave-like, thin-walled sleeve in cross section, where the sleeve stays with a front (17) on the bar. A joining (16) is immanent to another front (18), where the deflecting unit lies with its head circle at an inner shell (20) of the piston.
