Abstract
A fail-safe throttle positioning device is disclosed for an engine induction system. A throttle body is provided having a fluid passage. A movable throttle valve is disposed within the fluid passage for at least idle speed control. An actuator mechanism is connected to the throttle valve for operably moving the throttle valve between a minimum fluid flow position and a maximum fluid flow position. A fail-safe mechanism urges the throttle valve toward an intermediate position between the minimum and maximum fluid flow positions to prevent inoperability of the engine during failure of the actuator mechanism.
