Abstract
A hydraulic lash adjuster having a body (11) defining a blind bore (13) and a fluid port (35) in communication with a source of fluid pressure. Upper and lower plunger elements (17,19) are disposed within the body and define a low pressure fluid chamber (21). The upper end portion (53) of the lower plunger element (19) defines a series of openings (55) providing fluid communication from the bore (13) into the chamber (21). The bore (13) and the upper plunger element (17) define a radial clearance sufficient that the clearance and the openings (55) comprise substantially the only fluid path from the fluid port (35) to the chamber (21). The invention reduces the machining of the body (11) and the upper plunger (17) which are normally required, thus substantially reducing the cost of the lash adjuster.
