  • Liquid separator
    Patent number: 7779820
    Abstract: A liquid separator that can be used in a vehicle fuel system can have, among other components, an inlet portion, a deflector surface, and an outlet portion. The inlet portion can receive fluid from a fluid tube that communicates with a fuel tank. The deflector surface may cause a change-in-direction that separates liquid and fuel vapor from the fluid. The outlet portion can carry separated fuel vapor to a vapor tube that communicates with a canister. A space adjacent the inlet portion can be defined by a fuel system component such as partly by a fill tube or by a vessel.
