Claims

[Scope of utility model registration request]

(1) A first float chamber for gasoline, a second float chamber for internal combustion engine fuel other than gasoline, first and second fuel supply passages that supply fuel from both float chambers, respectively, and both fuels. a control valve that selectively communicates the supply passageway with a port to the main fuel passageway, said control valve being actuated to communicate the first fuel supply passageway with the port to the main fuel passageway upon introduction of manifold negative pressure; It has a valve body and is installed on the float chamber side near the main jet, and the negative pressure introduction passage of the control valve is connected to the negative pressure inlet pipe to the control valve when outside air or engine cooling water at startup or warm-up is below a specified temperature. 1. A vaporizer characterized by having an operation valve that shuts off the introduction of pressure to make it inactive, and when the temperature is above a specified temperature, introduces negative pressure into the suction pipe to the control valve to make it into an operating state.

(2) The operating valve is a negative pressure type, electric type, or bimetal valve that operates according to the outside air or engine cooling water temperature, or a valve that uses a heat-sensitive material such as wax, as stated in claim 1 of the utility model registration claim. vaporizer.
