ABSTRACT:
A device for a fuel vapor pressure management apparatus of a fuel system supplying fuel to an internal combustion engine. The fuel vapor pressure management apparatus performs leak detection on a headspace of the fuel system, performs excess negative pressure relief of the headspace, and performs excess positive pressure relief of the headspace. The device includes a seal that is deformable between a substantially symmetrically deformed configuration, a generally asymmetrically deformed configuration, and an undeformed configuration. The seal is adapted to cooperatively engage a poppet such that a first arrangement that includes the seal in the substantially symmetrically deformed configuration and the poppet engaging the seal, a second arrangement that includes the seal in the generally asymmetrically deformed configuration and the poppet engaging the seal, and a third arrangement that includes the seal in an undeformed configuration and the poppet being disengaged from the seal. The first arrangement is associated with the performing leak detection, the second arrangement is associated with the performing excess negative pressure relief; and the third arrangement is associated with the performing excess positive pressure relief.
