Abstract
A gasoline powered motor vehicle is provided with a tilt rsponsive shut-off valve in its fuel line to shut-off gasoline flow from the fuel tank to the carburetor when the vehicle is tilted. The valve includes a tee shaped shut-off passage having a first branch and a second branch connected in series between the valve inlet and the valve outlet. A tilt responsive ball valve in the first branch shuts off gasoline flow when the vehicle is tilted in one direction, and another tilt responsive ball valve in the second branch shuts off fluid flow when the vehicle is tilted in the other direction. Each of the ball valves includes a ball cavity for storing the ball when the vehicle is in an upright position and a reduced diameter restrictive passage leading from the ball cavity to retain the ball in a deactuated position under normal operating conditions by providing a combination mechanical and fluid barrier.
