  • Hydraulic lash adjuster
    Patent number: 6598572
    Abstract: A hydraulic lash adjuster has a plunger assembly the outer end of which can be moved inwardly until the inner end abuts a seal and closes a high pressure chamber, thus preventing further 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.
