ABSTRACT:
A fuel cap is provided for use in a threaded filler neck of a fuel system. The fuel cap includes a shell providing a hand grip and a closure rotatably engaging the threaded filler neck for closing the filler neck. The closure includes a seal for establishing a sealing engagement between the closure and the filler neck to block the escape of fuel and fuel vapor in the filler neck to the atmosphere. The cap also includes a pressure-vacuum valve assembly that extends through the closure for venting pressurized fuel vapor in the filler neck through the closure. The cap further includes an actuator providing an operative connection between the shell and the valve assembly so that rotation of the shell relative to the filler neck in a cap-removal direction will actuate the valve assembly. Such actuation enables pressurized fuel vapor to be vented from the filler neck prior to substantially rotating the closure relative to the filler neck and breaking the sealing engagement established between the closure and the filler neck. Preferably, the valve assembly includes a vacuum-relief valve operable by the actuator to release pressure in the filler neck. The closure also includes a frangible section that cooperates with an ejection system to urge the shell and the actuator away from valve assembly during a fuel cap breakaway accident.
