| description | A valve assembly for a fuel tank system including a fuel tank having a fuel tank outlet and a purge canister includes a main valve and a safety check valve. The main valve can be configured to move from a closed position to an open position. The main valve can have a main valve first port fluidly coupled to the outlet of the fuel tank and a main valve second port fluidly connected to the purge canister. The safety check valve can be configured to move from an open position to a closed position upon a pressure drop at the fuel tank outlet exceeding a predetermined threshold. The safety check valve can have a safety check valve first port fluidly coupled to the outlet of the fuel tank and a safety check valve second port fluidly coupled to the purge canister. |
