特徴とする圧送式油圧リフタ。The upper part engages with a bushing rod seat that engages with the bushing rod, the lower part abuts on a spring supported at the bottom of the cylindrical body, and is slidable up and down together with the bushing rod seat, and the bottom part is connected to a cam. A plunger is inserted into a body that engages and moves up and down, and has a passage formed in the body that communicates with an oil supply source, and a reservoir that allows oil to flow through the passage. A hydraulic lifter, wherein the reservoir communicates with a pressure chamber at the bottom of the body through a check valve, and the pressure chamber communicates with the passage through a leak gap between the body and the plunger, the pressure chamber being connected to the bottom of the plunger. is formed with a cylindrical part with an open bottom that protrudes into the pressure chamber and slides with the cylinder part of the body, and an air vent hole communicating with the leak gap is provided in the wall of the cylindrical part in the upper part of the pressure chamber. Pressure feed type hydraulic lifter.
