Abstract
In a throttle valve actuator, there are provided a first spline gear driven by a motor in a sliding operation, a second spline gear meshed with the first spline gear for rotating a shaft of a throttle valve device, a housing for rotatably supporting the second spline gear. An accelerator pedal is connected via an accelerator wire and the housing to second spline gear so as to rotate the shaft of the throttle valve device. The sliding operation of the first spline gear does not give any force to the accelerator pedal via the houisng and second spline gear.
Claims5
A throttle valve actuator comprising:
- accelerator pedal means;
- air pressure type drive means adapted to be controlled by the accelerator pedal means, for sliding a drive rod thereof;
- sliding/rotating movement converting means connected to said drive rod and a universal joint, for converting sliding force of said drive rod into first rotation force;
- output shaft means connected to said sliding/rotating movement converting means, for transporting said first rotation force to throttle valve means;
- housing means for rotatably supporting said output shaft means;
- and,
- motor means for rotating said throttle valve means via said housing means and output shaft means by second rotation force, whereby said throttle valve means is driven by both said first and second rotation force, and said second rotation force exerted by said motor means does not give any force to said accelerator pedal means via said sliding/rotating movement converting means universal joint, and air pressure type drive means.
