Abstract
An automatic fuel shut-off valve for the fuel line of an internal combustion engine which is responsive to crankcase pressure to open and supply fuel to the engine carburetor when the engine is operating. Pressure in the fuel tank cannot open the valve and thus the shut-off valve provides a safety device especially useful in household equipment.
