When the cam turns to the working surface, the tappet rises, and the valve spring tension acts on the plunger through the valve 04206378 push rod, but at this time the one-way valve is closed so that the oil cannot overflow, and the incompressibility of the oil makes the tappet like a A whole pushes the valve to open. During this process, due to the high oil pressure in the tappet body cavity, a little oil leaks out through the gap between the tappet body and the plunger, which shortens the working length of the tappet. When the cam turns over the working surface, the tappet descends, the valve is closed, and the oil pressure in the tappet body cavity also decreases, so the oil in the main oil passage pushes the check valve again and injects it into the tappet body cavity, replenishes the oil, and repeats Loop the above actions
