ROTARY THROTTLE VALVE AND CARBURETOR
20200032742 · 2020-01-30 ·

A rotary throttle valve for a carburetor may include a body and a throttle lever integrally formed with the body in one piece. The body may be generally cylindrical and adapted to be received in a cylindrical valve bore of a carburetor for rotation within and relative to the valve bore, and the body includes a valve passage through which air flows. The throttle lever is integrally formed with the body and adapted to be coupled to a driver that rotates the throttle valve. Among other things, by being integrally formed from the same piece of material as the valve body, the throttle lever can be accurately aligned with the valve body, and hence, the valve bore in which the body is received in use.
