Abstract
A hydraulic lash adjuster which is mounted in a rocker arm of an internal combustion engine. The plunger of the lash adjuster has a socket formed therein which receives a cylindrical member having a ball end in contact with the socket and a flat surface engageable with a poppet valve of the engine. The ball and socket connection is lubricated by engine oil flowing from the leakdown clearance space between the plunger and the lash adjuster body through a passage which intersects the socket surface. The plunger and the cylindrical member are retained within the body by a single, dish-shaped member which is positioned over the body.
