Claims

[Scope of utility model registration request]

It has a cylindrical outer plunger that is slidably fitted into a cylinder provided on the Rotsuker arm,
A cylindrical inner plunger having an orifice at the bottom is slidably fitted inside the outer plunger, and a plunger head is placed inside the outer plunger in contact with the open end of the inner plunger. A check valve is installed to allow oil to flow only from the reservoir chamber formed inside the inner plunger and the plunger head to the high pressure chamber formed between the inner plunger and the outer plunger. The oil introduction chamber communicates with the chamber through an oil supply port formed in the plunger head, and the oil introduction chamber communicates with an oil supply system formed in the rocker arm. In a hydraulic valve latch adjuster that is provided with a groove that communicates an oil introduction chamber with the atmosphere, an oil passage that opens for lubrication is provided approximately in the center of the sliding fitting portion between the outer plunger and the cylinder. A hydraulic valve latch adjuster, characterized in that it is provided on a Rockscar arm in communication with a Rockscar shaft oil passage.
