Hydraulic clearance compensating element for cam follower of internal combustion engine's valve gear

摘要

A limiting disc (22) is positioned in the bore (19) of the reservoir (18) in a section of the upper end face (5) of the pressure piston (6), and is spring-loaded (23) in the direction of the upper end face. The spring has such a spring force that the limiting disc with the non-application of hydraulic pressure presses the wider end face to close against the base of the chamber at the end of the cam follower or the bottom of the cam follower, and with the application of hydraulic pressure in the bore of the reservoir is displaced towards the first end face (13) of the piston.
