Claims

[Scope of utility model registration request]

The valve train of an engine includes a cam for driving the valves to open and close, and a lash adjuster for adjusting the valve clearance, which is interposed between the cam and the stem of the valve. A case in which the latch adjuster has a receiving surface that comes into contact with the cam, and a hydraulic high pressure chamber for transmitting the pressing force on the receiving surface of the case to the stem portion of the valve;
and a check valve capable of supplying high pressure oil to the high pressure chamber.In order to open the check valve when measuring dry lash of the lash adjuster, the valve of the check valve is mounted on the receiving surface of the case. A first hole that allows a rod-like member to move the body to pass through is formed, and a second hole that aligns with the first hole and allows the rod-like member to pass through the cam. An engine valve train with a latch adjuster, which is characterized by being formed.
