  • Passive evaporative emission control module
    Patent number: 7610905
    Abstract: An emission control module (14) includes a housing (52) that includes an atmospheric air opening (102) and a vapor emission inlet (104) for communication with a vapor region (32) of a fuel reservoir (16). A hydrocarbon filter (56) is disposed between the atmospheric air opening (102) and the vapor emission inlet (104) to passively filter vapor emissions within the vapor region (32). The housing (52) is configured for purging of the hydrocarbon filter (56) due to a low-pressure draw from the vapor emission inlet (104).
    Type: Grant

  • Integrated Vapor Management And Rollover Valve For A Fuel Tank
    Publication number: 20080105304
    Abstract: A fuel system comprising a fuel tank having an opening. A cap is removably coupled to the fuel tank and operable for sealingly closing the opening to prevent ingress and egress of air through the opening. An overfill chamber is in communication with the fuel tank, and a hydrocarbon collection chamber is in communication with the overfill chamber. A valve is disposed between the hydrocarbon collection chamber and the overfill chamber. The valve includes a reference axis and is configured to permit fluid communication between the overfill chamber and the hydrocarbon collection chamber only when an angle between a vertical axis and the reference axis is less than about thirty-five degrees.
