ABSTRACT:
A tilt responsive shut-off valve in a fuel line of a motor vehicle to shut-off fuel flow from a supply tank to a carburetor when the vehicle is upset in any direction. The valve includes an inlet passage, shut-off passage and outlet passage connected between the valve inlet and valve outlet. The shut-off passage includes dual ball members cooperating with a valve seat and each other to shut off fuel flow when the vehicle is upset beyond a predetermined amount. Under normal operating conditions, a sealing ball, biased toward a closed position, is held away from its associated valve seat face by a counterbiasing ball thereby permitting fuel flow through the valve.
