摘要： A fuel system for supplying fuel to an internal combustion engine. The fuel system includes a fuel tank, an intake manifold, a fuel vapor collection canister, a purge valve, and a fuel vapor pressure management apparatus. The purge is in fluid communication with the intake manifold and is in fluid communication with the fuel vapor collection canister. The fuel vapor pressure management apparatus includes a housing, a pressure operable device, and a switch. The housing is coupled to the fuel vapor collection canister and defines an interior chamber. The pressure operable device separates the interior chamber into a first portion that is in fluid communication with the fuel vapor collection canister, and a second portion that is in fluid communication with a vent port. The pressure operable device includes a poppet that is movable along an axis, and a seal that is adapted to cooperatively engage the poppet. A first arrangement of the pressure operable device occurs when there is a first negative pressure level in the fuel vapor collection canister relative to the vent port, and the seal is in a first deformed configuration. A second arrangement of the pressure operable device permits a first fluid flow from the vent port to the fuel vapor collection canister when the seal is in a second deformed configuration. And a third arrangement of the pressure operable device permits a second fluid flow from the fuel vapor collection canister to the vent port when the seal is in an undeformed configuration. The switch signals the first arrangement of the pressure operable device.

摘要： A device and method for preventing resonance in 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, a pressure operable device separating the interior chamber into first and second portions, and a device preventing resonance. The pressure operable device includes a poppet that is movable along an axis and a seal that is adapted to cooperatively engage the poppet. The device preventing resonance includes at least one of a dashpot defined by the housing and the poppet, a gap between the poppet and the seal, and a resilient element applying a force biasing the poppet toward the seal. The dashpot damps movement of the poppet associated with the performing excess positive pressure relief. The gap modulates fluid flow that occurs between the surface and the tip during the performing excess negative pressure relief. And the force is applied eccentrically with respect to the axis so as to damp resonance due to movement of the poppet associated with the performing excess positive pressure relief.
