Abstract (en)
A hydraulic lash adjuster has a plunger assembly (26) the outer end of which can be moved inwardly until the inner end abuts a seal (34) and closes a high pressure chamber (28), thus preventing further inward movement. This accommodates any necessary movement of a valve towards its closing position to ensure proper closure. Consequently, net-shaped cams wherein the base circle is not necessarily accurately concentric may be used. A leaf spring ensures opening of the chamber when the base circle of the cam is next reached. <IMAGE>
