Abstract
A hydraulic lash adjuster (130) for an internal combustion engine which includes a body (132) and a plunger (134) of thin-walled construction in which features such as hydraulic fluid collector volumes between the plunger and the body and a check valve seat (174) in the plunger are formed by selectively displaced regions (135,137) of the walls of the body (132). Because of the thin-walled construction of the body (132) and plunger (134), a resilient cap member (161) is in engagement with the upper open end of the body (132) and includes a lip portion in sealing engagement with the outside diameter of the plunger (134), the cap member (161) being rigid enough to help guide the plunger as it reciprocates within the body.
