초록

A fuel cap is provided with a vent system for lowering the actuation pressure of its internal pressure-relief valve in response to rotation of the fuel cap relative to the filler neck in a cap-removal direction. The vent system provides an operative connection between the cap handle and a pressure-relief valve in the cap. The vent system includes a spring for applying a closure-inducing force urging the pressure-relief valve against its valve seat to close a vent aperture in the cap, and a control system for regulating the magnitude of the closure-induci...
