Anti-overrunning device for an internal combustion engine
An anti-overrunning device is described for an internal combustion engine, comprising: (a) a carburetor having a venture passage for a fuel and air mixture, (b) a throttle valve in the passage movable to open and closed positions to regulate the effective area of the passage, (c) an actuator including a diaphragm responsive to pneumatic pressure operatively connected to the throttle valve, (d) an inertial pump comprising a housing having a weighted diaphragm mounted on an engine and subject to engine vibrations to develop pneumatic pressure, the inertial pump having an outlet connection to the actuator, and (e) a vibration sensor valve interposed in the outlet connection between the inertial pump and the actuator responsive to excessive vibration of the engine to connect the pump pressure to the actuator to cause movement of the throttle valve in a closing direction to reduce the speed of the engine.
