ABSTRACT:
A fuel cap is provided for use in a fuel system filler neck having a mouth. The cap includes a closure rotatably engageable with the filler neck to cover the filler neck mouth and formed to include a vent passageway extending therethrough in communication with the filler neck. A valve is supported in the vent passageway for movement between passageway-opening and passageway-closing positions. The cap further includes a handle shell and a plunger. The handle shell includes a lost-motion drive member positioned to apply a rotation-inducing drive force to the closure upon a predetermined amount of rotation of the handle shell. The plunger is supported in a space between the handle shell and the closure for movement between inactive and valve-actuating positions. The handle shell also includes at least one cam member configured to move the plunger to its valve-actuating position upon rotation of the handle shell in a cap-removal direction, thereby moving the valve to its passageway-opening position before the lost-motion drive member is able to rotate the closure relative to the filler neck.
