Poppet for a fuel vapor pressure management apparatus |
摘要 |
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 housing defining an interior chamber, and a poppet movable along an axis. The poppet includes a perimeter that has a plurality of notches. Interposed between each adjacent pair of the notches is a corresponding tab, and each tab includes a radially outer edge that is adapted to cooperate with the housing so as to guide movement of the poppet that is associated with the performing excess positive pressure relief.
