ABSTRACT:
A fuel interception valve which is installed to upper opening portion of a fuel tank, wherein at the normal state, the valve is opened and draft state is maintained, and at the liquid level rising state and the reversing state of the valve box, the valve is closed and the fuel is prevented from flowing away. The fuel interception valve comprises a valve box of cylindrical shape provided on upper side with a valve hole for draft; a valve body means loosely inserted in the valve box for opening and closing the valve hole in the valve box; a float arranged at lower side of the valve body means and having specific gravity smaller than that of the fuel for pushing up the valve body means to the valve close position; and a weight means acting on the float at the reversing state of the valve body and having specific gravity larger than that of the fuel for moving the valve body means to the close position.
