ABSTRACT:
A control system for a throttle valve in automotive internal combustion engines in which the throttle valve is both mechanically linked with an accelerator pedal and also connected with an actuator such as a pulse motor for fine-adjusting the opening of the throttle valve in the closing direction in accordance with the operating state of the engine after it has been opened through the mechanical linkage. A spring is inserted in the mechanical linkage system between the accelerator pedal and the throttle valve. The provision of the spring substantially isolates the accelerator pedal from forces acting in other parts of the system so that the operator does not feel an unnatural change in the amount of pressure needed to depress the accelerator pedal when the actuator goes into operation.
