According to the type of throttle, carburetor can be divided into rotary type and lifting type. The rotary throttle valve is a disc-shaped throttle valve, which rotates around the axis between the carburetor throat and the intake pipe to change the flow area of the intake pipe.

The lifting throttle valve is a bucket-shaped plate throttle valve, which moves up and down in the throat to change the channel area of the throat. This form is often used in motorcycle carburetor.

The rotating throttle is controlled by people, and the lifting throttle is controlled by diaphragm, which is also often used on motorcycles and is called CV type.
