Abstract

See full text

A device for shutdown of an internal combustion engine which provides for the cessation of fuel and air mixture in a carburetor supplying the cylinders of the engine with fuel for ignition. The device features a conduit in sealed engagement with the fuel supply bowl of the carburetor which may by switched from engagement between the atmosphere or a negative air pressure supply. When switched to communication with negative air pressure the device causes a vacuum in the fuel bowl of the carburator thereby ceasing fuel flow and shutting down the engine due to lack of fuel.
