ABSTRACT:
A motor vehicle throttle valve positioner consisting of an elongated screw means moving the throttle valve and providing two ranges of movement, one being an engine idle speed mode of operation to maintain the engine at the correct idling speed level as determined by a microprocessor or similar electronic control, the other being a speed control mode of operation wherein a chosen engine off-idle speed level is maintained, and a failsafe operation returning the throttle valve to the idle speed range in the event of electrical failure or termination of the speed control mode of operation.
