ジャ内へ押し込む方向に付勢する圧縮ばねとを設け、か
つピストン下方のプランジャ周壁にプランジャの外周に
漏れたオイルを油室へ流す油室を適数設けたことを特徴
とする内燃機構用動弁機構の油圧アジャスタ。An oil chamber formed by a bottomed cylindrical adjuster body and a peripheral wall with an open top has a communication hole in the center of the bottom of the adjuster body, and a hydraulic chamber is formed between this bottom and the bottom of the adjuster body. A plunger that is slidably inserted into the adjuster tenon in the axial direction, a check valve that is located in the hydraulic chamber to stop the flow of oil from this chamber to the oil chamber, and a return spring that biases the plunger upward. A hydraulic adjuster for a valve mechanism for an internal combustion engine, wherein the adjuster body is slidably and rotatably fitted into a mounting hole of a rocker arm with its bottom facing the tip of a valve stem of an intake or exhaust valve. , a piston that slides oil-tightly against the inner peripheral surface of the plunger and a compression spring that biases the piston in the direction of pushing it into the plunger are provided on the opening side of the peripheral wall of the plunger, and a compression spring is provided below the piston. A hydraulic adjuster for a valve train for an internal combustion engine, characterized in that a suitable number of oil chambers are provided on the plunger peripheral wall to allow oil leaking around the outer periphery of the plunger to flow into the oil chamber.
