Reed valve device for 2-cycle engine |
摘要 |
A reed valve device for a 2-cycle engine includes a valve housing having several ports extending thereinto from a surface thereof. Several reed valves each have one end secured to the housing and can move between a position spaced from the surface and a position disposed against the surface and obstructing a respective port. Two main shafts are rotatably supported on the housing, and are coupled for synchronous rotation by a gear plate arrangement. Each main shaft has thereon a stopper which can move between positions engaging and spaced from the reed valve in response to rotational movement of the associated shaft, engagement of a stopper and a reed valve effecting an increase in a spring constant of the reed valve. When the engine exceeds a predetermined speed, a motor rotates the shafts to move the stoppers into engagement with the reed valves.
