<p>PURPOSE:To make sure the operation of intake air over the whole range of engine revolution by installing a plurality of concaved parts which are mutually independent in substance, on the surface of a reed valve. CONSTITUTION:A reed valve 40 is made of plate materials such as SUS material, and the base of the reed valve is fixed at a part close to the flange part 34 of a body inclination part 32 by means of screw 35, and the top free end of the reed valve 40 is elongated to the top of the valve hole opening part 33. On each surface 40a of the reeds 41a-41c, a number of concaved parts 44 are formed, constituting each independent part in substance, and between said concaved parts 44, projected frame parts 45b are formed mutually and continuously so as to surround the concaved parts 44 and to be continuous to the preipheral surrounding frame part 45a, and these frame parts 45a and 45b form a part of the surface 40a of the reed valve 40.</p> |
