Claims

[Claims for Utility Model Registration] 1. A vaporizer in which liquid fuel in a float chamber is sucked into a primary system bore and a secondary system bore according to the air pressure in these bores and mixed with air, Inside the multi-system bore, there is a secondary nozzle from which the liquid fuel is discharged, a throttle valve that opens and closes the downstream side of the secondary nozzle, and a throttle valve that is located upstream from the secondary nozzle and controls the air pressure within the secondary system bore. In the carburetor provided with an air valve that changes the opening degree according to the change in the air pressure, a protruding member that protrudes from the inner wall side of the secondary system bore toward the axis of the bore is provided between the secondary nozzle and the throttle valve. A vaporizer characterized by five provided. 2. The above-mentioned projecting member is a substantially annular member centered on the axis of the secondary system bore. 5$:':H is comprised of triangular fins arranged at approximately equal intervals in the circumferential direction on the axial center side of the secondary system bore. The vaporizer according to item 2.
