Abstract
A throttle drum with a first return spring disposed therearound is rotatably mounted on a throttle shaft, and a cruise control drum with a second return spring disposed therearound is rotatably disposed around the throttle drum. The throttle drum and the cruise control drum are arranged in a radially double-walled structure around the throttle shaft, which may be of a relatively short axial length.
Claims16
A throttle valve control device comprising:
- a throttle shaft;
- a throttle lever fixedly mounted on said throttle shaft;
- a first operating drum rotatably mounted on said throttle shaft and angularly movable by an accelerator pedal for engaging said throttle lever to angularly move said throttle shaft about its own axis;
- a second operating drum disposed around said first operating drum and angularly movable by a cruise control system for engaging said throttle lever to angularly move said throttle shaft about its own axis;
- a first return spring disposed around said first operating drum for normally urging said first operating drum to angularly move back to a predetermined position;
- and
- a second return spring disposed around said second operating drum for normally urging said second operating drum to angularly move back to a predetermined position.
