Abstract
An anti-overrunning system for an internal combustion engine having a throttle valve in a carburetor in which an actuator for the throttle valve is responsive to pump pressure to move the valve to a closing position. A vibrating pump responsive to engine vibration is located to direct output control pressure to the actuator. A control valve between the pump and the actuator normally blocks pressure to the actuator but is responsive to air pressure from an engine cooling fan such that, upon overrun conditions, the fan pressure will actuate the control valve to connect the pump to the actuator to cause the throttle valve to move toward a closing position.
