密封式油圧タペット。A cylindrical plunger whose upper surface abuts a bushing rod is slidably and movably inserted into a cylindrical body whose lower surface abuts a cam. While imparting spring force,
A diaphragm is provided in the plunger, and an oil storage chamber is formed between the outer peripheral surface of the diaphragm and the inner peripheral surface of the plunger.The pressure chamber and the oil storage chamber are connected by a passage, and these chambers are filled with hydraulic oil, and the oil storage chamber is formed in the passage. In a hydraulic tappet provided with a check valve that allows hydraulic oil to flow from the oil storage chamber to the pressure chamber side, means for controlling the amount of hydraulic oil flowing from the oil storage chamber to the pressure chamber due to an unexpected decrease in the load applied to the plunger. A hydraulic tappet sealed with hydraulic oil, characterized in that the check valve is provided with:
