  • Valve assembly for a fuel tank
    Patent number: 6648016
    Abstract: A valve assembly for admitting a tube or fuel into a vehicle fuel tank is disclosed. The valve assembly has a fixed housing with an inlet, an outlet, a middle section and an inner surface with an opening. At least one projection depends from the inner surface between the inlet and the outlet. The projection deflects the tube toward and through the opening. A piston element, which is slidably mounted to the housing, is normally urged in a direction to close the outlet and the opening until the tube or fuel urges the piston element in an opposite direction.
