Claims

[Scope of Claim for Utility Model Registration] (1) Throttle valve shaft 4 on the idle opening adjustment screw 37 side parallel to the high speed fuel needle valve 35 and the low speed fuel needle valve 36
The flat throttle valve arm 41 fixed at 0 has an idle opening stop portion 47 that corresponds to the tapered end portion 46 of the idle opening adjustment screw 37 protruding from the top of the idle opening adjustment screw boss 43, and an idle opening adjustment portion Fully open stop portion 48 that hits the throttle valve side end surface 44 of the screw boss 43
and an operating part 49 corresponding to a throttle valve operating rod or cable depending on the rigging, and a throttle valve arm 41 and a carburetor main body 3.
1 and the throttle valve return spring 4 fitted into the throttle valve shaft 40 between the
Hook the U-shaped hook part 2 onto the throttle valve arm 41, and apply the spring end on the carburetor main body 31 side to the throttle valve side end surface 44 of the idle opening adjustment screw boss 43 so as to press the throttle valve 38 in the fully closing direction. The other end of the throttle valve arm 41 is connected to the throttle valve shaft 40.
There is a lateral movement regulating fitting 4 that touches the surface of the carburetor main body 31.
5. A butterfly-shaped throttle valve type membrane chamber type vaporizer. (2) When the throttle valve 51 is fully closed, the throttle valve starting opening operating arm 55 attached to the throttle valve arm 53 is applied to the throttle opening cam portion 50 attached to the flat throttle valve arm 41 to start the throttle valve 38. 2. A butterfly-shaped throttle valve membrane chamber type vaporizer according to claim (1) of the registered utility model, characterized in that the opening degree is set as the opening degree.
