Hydraulic play compensation element

摘要

A hydraulic play compensation element for the drive of a valve of an internal combustion engine with a housing in which a hollow piston is mounted such as to be acted upon, via a non-return valve, by oil pressure, the hollow piston being surrounded by an oil reservoir which communicates via an oil passage with the inner space of the hollow piston and in which a sleeve is inserted which with a part of its wall forms an oil transfer channel between an oil inlet in the housing and an upper region of the reservoir.
