デコンプ装置。 A decompression valve that is equipped with a decompression device that releases the compression pressure in the combustion chamber during the compression stroke at startup, and that forms a decompression port that communicates with the combustion chamber, and that opens and closes this decompression port and can be opened and moved by the suction force on the combustion chamber side. At the same time, a decompression spring is provided to close this decompression valve, and the biasing force of this decompression spring is applied to the negative pressure generated during the explosion stroke that follows after the compression pressure during the compression stroke is released by the operation of the decompression valve. 1. A decompression device for an engine, wherein the decompression valve is opened and opened by suction.
