Abstract
A hydraulic lash adjuster of the type in which the plunger assembly (15) includes a ball plunger element (50), and defines a valve opening (57) in the lower plunger member (19). A check valve member (53) is seated in the valve opening (57), for opening the valve opening in response to a relative decrease in the pressure in a high pressure chamber (23). The ball plunger element (50) includes a metering valve element (45) movable between an outward position (FIG. 1) and an inward position (FIG. 2). An elongated member (65) is fixed to move with the metering element (45), and includes a lower end (67) juxtaposed the valve opening (57). When the metering element (45) is in its inward position, the lower end (67) engages the check ball (53) and lifts it from the valve opening, thus facilitating assembly of the lash adjuster, filled with fluid, into an engine.
