弁間隙自動調整式油圧ロッカアーム。A hydraulic rocker arm for automatically adjusting the valve gap of an internal combustion engine, which is pivotally supported by a rocker shaft and has one end in contact with a cam of a camshaft and the other end in contact with the upper end of a valve stem of an intake/exhaust valve. A mounting hole is provided at the part that abuts on one side, and the upper end of the mounting hole is oil-tightly covered with a cap, which communicates with the mounting hole through a partition wall having a through hole at the top and communicates with the oil passage of the rocker arm. Further, the mounting hole is provided with a plunger that slides oil-tightly into the hole and forms an oil-tight chamber together with the mounting hole, and a check valve that closes the through hole on the plunger side. Features a hydraulic rocker arm with automatic valve gap adjustment for internal combustion engines.
