Abstract
A float chamber is in communication with the surrounding atmosphere through a valve actuatable in response to a negative pressure in an intake manifold so that when an engine is excessively inclined or upset the valve is closed under the pressure of the fuel in the float chamber. Therefore, the overflow of the fuel into the carburetor barrel may be prevented and a fire in the vehicle avoided.
