Claims

[Scope of utility model registration request]

A slide valve 3, which has a jet needle 4 inserted into a needle jet 5 opening into the main intake passage 2 to form an annular fuel passage and is attached to its lower end, intersects with the main intake passage 2 and moves forward and backward. A float chamber body 6 is disposed in contact with the lower surface of the carburetor housing 1 forming the main intake passage 2 to form a float chamber 7, and a fuel inflow path 1 to the float chamber 7 is formed.
1 is formed in the housing 1, and includes a float valve 12 which conducts and shuts off the fuel inflow path 11 via a float 14 disposed in the float chamber 7 in response to a rise and fall of the oil level 13 in the float chamber 7. The part of the housing that is attached to the lower surface of the housing 1 together with a bearing member 16 that supports the rotating shaft 15 of the float 14, hangs down into the float chamber 7, accommodates the needle jet 5, and forms the main fuel passage is a jet block. A semi-downdraft sliding valve type carburetor which can be used by using the housing 1 of the horizontal sliding valve type carburetor formed separately as 8 and tilting the main intake passage 2. , instead of the jet block 8,
A semi-contact structure consisting of a portion 8a-1 that accommodates a needle jet 5a into which the jet needle 4 is inserted, and a hanging portion 8a-2 that forms a main fuel passage through which the fuel in the float chamber 7 is guided to the needle jet 5a. A downdraft sliding valve type carburetor jet block 8a is used, and the housing 1 is equipped with the float valve 12.
and a semi-downdraft in which a fuel inlet passage 11 in which a float valve 12 is arranged in place of the float chamber body 6 and a bearing portion 16a that supports the rotational movement 15 of the float 14 are formed without attaching the bearing member 16. 1. A semi-downdraft sliding valve type vaporizer using a float chamber body for a sliding valve type vaporizer according to the present invention, and having a float adapted to the float chamber formed by the float chamber body.
