Abstract
An anti-overrunning device for an internal combustion engine which includes a carburetor with a controlled throttle valve. An actuator for the throttle valve includes a spring-biased rod mounted on a diaphragm. The rod normally urges the throttle valve to a closing position. The actuator includes a pressure actuated diaphgram responsive to pressure from a vibrating pump. This pressure tends to open the throttle valve. A vibration sensor is positioned to relieve pressure on the diaphgram of the actuator and, in response to overrunning of the engine, causes the throttle valve to close in under the influence of the spring bias.
