ABSTRACT:
A rotary throttle carburetor in which an air passage leading to the engine has a crossbore to receive a cylindrical rotary throttle having a throttle passage to regulate the air passage. A constant pressure device is mounted on the carburetor body directly below the rotary throttle and a short straight fuel passage connects a constant pressure chamber of said device with the throttle passage of the rotary valve. A fuel pump device can be mounted between the carburetor body and the constant pressure device to supply fuel to the constant pressure chamber and also to insulate the constant pressure device from the carburetor body to reduce vaporization.
