E字状の形状をしている。To further explain, if the reed valve 6 is made of wood, it is punched out of a thin plate material impregnated with mmM resin, or if it is made of metal, it is punched out by press punching from a thin metal plate material such as stainless steel. Three movable opening/closing parts 5a, 5a, . . . for opening and closing each outlet 4 extend from the base 6b and have a substantially E-shape.

れている。Further, the stopper 7 is moved from the fs portion 7b to the [Ffl leap movable portion 6
It is formed into a substantially E-shape in which three restraining portions 7a, 7a, . . . , shorter than a are extended. Further, around each outlet 4 of the support 5, a valve seat 9 made of a rubber cushion or the like that is compatible with each open/close movable part 6a of the reed valve 6 is provided.

る。In the reed valve device 1 formed in this way, each one of the reed valves 6 is closed during the exhaust and suction strokes in which the pressure of the suction part on the engine side is lower than the pressure on the carburetor side.
The lflrr1 movable part 6a is sucked outward and moves from the fully open state indicated by the line 4I in FIG. 6 to the fully open state indicated by the solid line in the figure, opening each outlet 4 and sucking fuel into the combustion chamber of the engine. On the other hand, during the compression, explosion, and expansion strokes in which the pressure in the suction section on the engine side is higher than the pressure on the carburetor side, the movable opening/closing tlIJ6a of the reed valve 6 changes from the fully open state shown by the solid line in the figure to the fully open state shown by the chain line in the figure. Go back and make each outlet 4 full ffJ.

不都合があった。However, when the conventional reed valve 6 made of a resin or metal thin plate is attached to the valve body 2 without a valve seat 9, the reed valve 6 is directly connected to the support 5 made of resin or gold. As a result of the violent and repeated collisions, the reed valve 6 quickly chips at the part where it contacts the support 5, making it impossible to properly open and close the valve, resulting in problems such as poor suction of vaporized fuel. there were.

次に、本実施例の作用を説明する。As one base material 12 of this reed valve 11, it is preferable to use a thin plate material having a high natural frequency, such as glass fiber or carbon fiber impregnated with a resin material. The other metal layer 13 may be made of a material that is more durable than the base material 12, and may be formed by adhering metal foil to the base material 12, or by depositing metal on the base material 12, etc. It may be formed by means of. Furthermore, gold rI, which is a type of gold R layer 13! The material of the foil may be selected from among crystalline metal foils such as stainless steel foils, non-crystalline metal foils such as amorphous alloys, etc., depending on the design conditions. In other words, although amorphous metal foil is more expensive than crystalline metal, it has superior mechanical properties such as hardness and strength, as well as superior chemical stability (corrosion resistance). It is advisable to select one that conforms to the design criteria n, etc. while considering the properties. - Next, the operation of this embodiment will be explained.
