Abstract
Lubricating oil through the lash adjuster body is directed first into a reservoir formed by a plunger reciprocating within the lash adjuster body and then through a central passageway formed in the closure element which element forms the pivot for the rocker arm. A plate is positioned in the plunger cavity intermediate the reservoir and lower end of the closure element, the latter having a groove extending radially from the central passageway to the clearance between the plunger wall and closure element. The plate is urged by the oil pressure in the reservoir against the lower end of the closure element forming with the groove a restricted passageway which meters the oil flow to the lubricating arm. The plate is also a check valve during engine start up to prevent the ingestion of air into the plunger.
