Abstract:
A vehicle fuel fill pipe shut-off device, comprising a valve housing adapted to be disposed on a side of a fuel tank and a fuel shut-off valve in said housing normally closed relative to a valve seat that is disposed in a path of fuel flow through a fuel fill pipe to said fuel tank, said valve being connected to a diaphragm in a manner to define in part a chamber communicated by a first orifice to said fuel fill pipe and by a second orifice to said fuel tank during fueling of said fuel tank below a predetermined fuel level, said valve being opened during said fueling by fuel introduced through said fuel fill pipe to said fuel tank, and a closure member for interrupting communication between said second orifice and said fuel tank when fuel level in said fuel tank reaches the predetermined fuel level to permit movement of said valve toward said valve seat and achieve closing of said valve to prevent further filling of said fuel tank with fuel, said closure member being connected to a fuel float disposed in an upstanding sleeve adapted to be disposed in said fuel tank and movable up and down in said sleeve in response to fuel level therein.
