Transmission element for reciprocating piston internal combustion engines

A transmission element comprising a rocker arm for a reciprocating piston internal combustion engine that is actuatable on one side by a cam of a camshaft and on the other side is in active connection with at least one gas exchange valve directly or via an intermediate arrangement of a valve bridge, and a hydraulic valve lash compensation element arranged at a force transmission end of and attached to the rocker arm,

• the hydraulic valve lash compensation element includes a plug-in extension with a first sleeve portion defining a first outer diameter, a second sleeve portion defining a second outer diameter that is greater than the first outer diameter, and a radially extending stepped portion connecting the first sleeve portion and the second sleeve portion, the first sleeve portion being attached to the rocker arm, and
• a valve piston is slidingly engaged against a radially inner surface of the first sleeve portion of the plug-in extension, and a working piston is slidingly engaged against a radially inner surface of the second sleeve portion of the plug-in extension,
• the radially extending stepped portion of the plug-in extension defines a shoulder that abuts directly against an axial surface of the rocker arm, and
• a compression spring is arranged within the plug-in extension, and the shoulder of the plug-in extension defines an axial stop surface for the compression spring and the working piston.
