Abstract
A hydraulic lash adjuster of the closed-type including a closed cylinder with a plunger positioned therein defining a hydraulic chamber at the closed end of the cylinder. An annular diaphragm extending between the cylinder and the plunger as a reservoir. A passage provides communication between the reservoir and the hydraulic chamber with a check valve preventing flow from the hydraulic chamber to the reservoir. A passageway extends axially through the plunger and is closed off by means of a soft plug in an area of greater diameter intermediate the ends of the passageway. Retainers hold the annular diaphragm in place with the retainer associated with the plunger extending inwardly to the plunger within the diaphragm to conserve on axial length of the mechanism.
