Claims

[Scope of utility model registration request]

A cylindrical sleeve with a closed end is fitted into the through hole provided in the Rocker arm with the lower flange in contact with the lower surface of the Rocker arm, and an orifice is fitted at the bottom of the cylindrical outer plunger fitted into this sleeve. A cylindrical inner plunger is slidably fitted therein, a closing head is placed in contact with the open end of the inner plunger, and an inner plunger is inserted into the bottom of the inner plunger from a reservoir chamber formed inside the inner plunger. A check valve is placed to allow oil to flow only in the direction of the high pressure chamber formed by the plunger and the outer plunger, and the reservoir chamber and oil introduction chamber are communicated through an oil supply port formed in the inner plunger, and oil is introduced. The room is
Through a refueling opening provided in the sleeve,
A groove is provided in the top surface of the closing head, which communicates with an oil supply system formed in the rocker arm, and communicates the oil introduction chamber with the atmosphere through an outlet formed in the closed end of the sleeve. In the hydraulic valve latch adjuster, an annular recess is formed in the inner wall of the sleeve portion constituting the oil introduction chamber, facing the oil supply opening, and a ring for opening and closing the oil supply opening is formed in the annular recess. A hydraulic valve latch adjuster characterized by having a resilient cylindrical split ring pressed into contact.
