Claims

[Scope of utility model registration request]

A float chamber body 15 is disposed in contact with the lower surface of the carburetor housing 1 to form a float chamber that maintains a constant oil level, and the hanging portions 6 and 10 of the housing 1 to the float chamber are provided with the constant oil level. A fuel passage having an opening at the bottom and guiding fuel to the main intake passage 7 of the carburetor is formed, and the constant oil level is disturbed by the swinging of the fuel in the float chamber, and the constant oil level is lowered below the constant oil level. A fuel swing suppression plate 2 is disposed surrounding the hanging portions 6 and 10 to prevent the openings from being exposed to the air. In a carburetor equipped with a float valve 4 that opens and closes in conjunction with the float, and a valve seat body 3 that forms a guide surface 3a and a valve seat 3b of the float valve 4, the fuel swing suppression plate 2 is connected to the float arm 11. Bracket 12 that pivots the
and the valve seat body 3 are integrally molded from synthetic resin to form one molded body 18, and an O-ring 19 is interposed in the fuel introduction opening 5a formed on the lower surface of the housing 1 to form a single molded body 18. The molded body 18 is positioned by elastically inserting the body 3 and sandwiching the projecting piece 20 formed to protrude horizontally from the molded body 18 between the housing 1 and the float chamber body 15. A vaporizer characterized by:
