のタイミング可変装置。In the rotary disc valve of a two-stroke engine, which opens and closes the intake passage by rotating a circular disc with a fan-shaped notch, the disc on the trailing side of the notch has a two-disk structure, and the inner surface of the disc has a diametrical recess. A groove is provided, and a slidable centrifugal weight and a coil spring that urges the centripetal weight in the centripetal direction are housed in the groove.
An auxiliary valve accommodated in the hollow part so as to cover the groove is rotatably supported on the centripetal side, and the auxiliary valve is provided with a guide inclined in the centrifugal direction, leap, and swing side with respect to the groove. A timing variable device for a two-cycle engine rotary disc valve, characterized in that a groove is provided to engage a part of the weight.
