デコンプ装置。In a device that operates a tappet with a cam provided on the camshaft by the rotation of the camshaft that receives rotational force from the crankshaft through the cam gear to open and close the intake valve and the exhaust valve for the combustion chamber, the intake or exhaust valve is opened and closed from the cam gear. An axial groove with a semicircular cross section is formed on the outer periphery of the camshaft that is attached to the exhaust cam, and a release pin with a circular cross section is rotatably inserted into this groove with a part of the outside protruding.
The flyweight on one side of the release pin is positioned on the reaction force side of the cam gear, and the notch formed at the end of the release pin on the side opposite to the flyweight is fitted into the groove of the intake or exhaust force l. □ Make sure that this notch protrudes and retracts from the cam surface as the release pin rotates.
A decompression device for an engine, characterized in that the combustion chamber is brought into a semi-compressed state by protruding from the cam surface of the notch, and the combustion chamber is brought into a fully compressed state by recessing the notch into the cam surface.
