Abstract
A throttle control apparatus for an internal combustion engine which is compact in size, highly safe in operation, and applicable to a cruise control device without requiring any operator's accelerator pedal operation. The throttle control apparatus comprises: a throttle valve disposed in an intake pipe for adjusting the flow rate of intake air supplied to the engine; a valve shaft rotatably supported on the intake pipe and fixedly mounting thereon the throttle valve for rotation therewith; a throttle lever fixedly mounted on the valve shaft for rotation therewith; a motor operatively connected with the throttle lever for driving the throttle lever to thereby adjust the opening degree of the throttle valve; a power transmitting mechanism operatively connected between the throttle lever and the motor for transmitting power from the motor to the throttle in such a manner that the throttle lever is forced to rotate by the motor; an accelerator pedal adapted to be operated by an operator; a rotary disk rotatably mounted on the valve shaft and operatively connected with the accelerator pedal in such a manner that it is rotated around the valve shaft as the accelerator pedal is operated by the operator; and a rotation limiter for limiting relative rotation between the throttle lever and the throttle disk to a predetermined rotational range whereby the maximum opening degree of the throttle valve due to the motor is limited to a certain level which corresponds to the amount of operation of the acceleration pedal due to the operator.
