関の動弁装置。 A body and a plunger that are mutually slidable and form a high pressure chamber between the cam and the valve stem, and a plunger spring that is provided between the body and the plunger and biases the high pressure chamber in a direction to expand the high pressure chamber. In a valve train for an internal combustion engine equipped with a hydraulic latch adjuster, which has a check valve that opens only in the direction of introducing hydraulic pressure into a high pressure chamber, a valve non-lift valve is installed between a cam and a valve stem. stronger than the plunger spring force and hydraulic pressure inside the hydraulic lash adjuster.
A valve train for an internal combustion engine, characterized in that an elastic body having an elastic force weaker than the set load of a valve spring is interposed.
