ABSTRACT:
A self-contained hydraulic lash adjuster having a cup-shaped body and a plunger slidably disposed therein is further provided with a flexible diaphragm secured within a reservoir chamber located in the plunger with one side of said diaphragm being exposed to the atmosphere and the other side being disposed in engagement with the oil supply sealed within the hydraulic lash adjuster. An oil passage is provided in the bottom of the plunger to communicate the reservoir chamber with a pressure chamber defined between the bottom of the plunger and the bottom of the body and a one-way check valve is provided to prevent the return flow of oil through the oil passage to the reservoir. A cup-shaped cover member having apertured side walls is located in the bottom of the plunger over the oil passage to prevent the diaphragm from blocking the oil passage upon deformation of the diaphragm.
