| description | A hydraulic support element for a switchable cam follower of a valve drive of an internal combustion engine, which has a pot-like housing with a bore, a pressure piston formed in one piece with an external casing and head projecting over an edge of the housing and a high pressure space for a hydraulic medium. The high pressure space is supplied, via a non-return valve from a first reservoir space, which is fed via first passages in the housing and pressure piston. A second reservoir space is formed in the pressure piston axially above the first reservoir space and is filled by second passages in the housing and pressure piston. From the second reservoir space a hydraulic medium is conducted to the cam follower via an opening in the head. The reservoir spaces are separated by a ball around which the internal wall of the pressure piston is wrapped. |
