特徴とする吸排気弁作動停止装置。゛ A tappet provided below the bushing rod that operates the intake and exhaust valves of the engine is connected to a plunger that receives the bushing rod, a piston provided below the plunger that moves only in the vertical direction, and a piston that opens upward and connects to the plunger. It consists of a tappet body that houses a piston, and a hydraulic device that supplies hydraulic oil to the tappet body, and a spring that presses the plunger and the piston to separate them, and a spring that is engaged when the piston rises. ratchet tooth-shaped retaining protrusions for rotating the plunger by 174n (n is a natural number) are provided on each opposing surface;
A spring that presses the plunger downward is provided between the plunger and the tappet body, and an engagement protrusion and an engagement stage that rotate the plunger by an additional 1/4n when the piston descends to alternately support or disable the plunger. The hydraulic device uses engine lubricating oil as hydraulic oil to move the piston up and down once each time an intake/exhaust valve is activated and stopped and released. An intake/exhaust valve operation stop device.
