Abstract: A vent valve assembly utilizes a lever arrangement that opens a vapor discharge opening such as during normal operation of a motor vehicle to permit fuel vapor venting and that seals the vapor discharge opening such as when the motor vehicle is inclined to prevent liquid fuel from discharging through the vapor discharge opening.

Abstract: A low permeation weldable fuel tank assembly is provided to reduce fuel vapor permeation from a fuel tank. The weldable fuel tank assembly has a mounting portion mountable to the fuel tank and a valve housing that is attachable to the mounting portion. In one aspect, the mounting portion includes a fuel vapor permeation barrier. In another aspect, an anti-permeation cap with a fuel vapor permeation barrier is affixed to a portion of a tank assembly.

Abstract: An adjustable lumbar support (10) adapted to be easily integrated into new or existing seat structures. Adjustable lumbar support (10) includes a floating plate (15) supported by a support linkage. In one embodiment, the support linkage is defined by a cable member (21) and first and second spring members (25) and (26) which engage the seat frame. In an alternate embodiment, the support linkage is defined by first and second spring members 25 engaged with first and second linkage members (52), respectively, and includes a rotary power mechanism (50) for applying a rotating motion to a shaft (54) threadably engaged with first and second linkage members (52). The degree of support provided by floating plate (15) is adjusted by adjusting the effective length of the support linkage. Lumbar support mechanism (10) can be mounted in a state of the art seat back alone or in conjunction with an integral trim attachment array (70).

Abstract: A fill limit vent valve assembly includes a cover assembly, a valve assembly and a fill control system.

Abstract: An adjustable lumbar support (100) adapted to be easily integrated into new or existing seat structures. Adjustable lumbar support (100) includes a lower floating plate (115) that is adapted to have a second, or upper, plate (130) hinged relative to the lower plate (115). The upper and lower plates have independently actuated support linkages (120 and 140) that are selectively actuated by first and second actuating mechanisms. In this manner, selective actuation actuator mechanisms associated with the lower and upper support plates (115 and 130) provides adjustment of a vertical dimension of the adjustable floating plate lumbar support. The degree of support provided by floating plates (115 and 130) is adjusted by adjusting the effective length of the support linkages.

Abstract: An apparatus for attachment in an aperture of a fuel tank includes a cap member, a mounting portion, and a valve housing. Two or more of the cap member, the mounting portion, and the valve housing include a system of clips and catches or a system of helical threads, which attach the components together. The mounting portion may include a multi-layer laminate to reduce a fuel vapor permeation from the fuel tank. The cap member, the mounting portion, and the valve housing are attached by various steps and methods according to the invention.

Abstract: A valve assembly for attachment in an aperture of a fuel tank wall includes a cap member with a nozzle, a carrier stage, a float stage, and a float housing. The carrier stage has a carrier carrying a sealing element with a relatively larger orifice opposing a relatively smaller orifice. The float stage includes a pivot pin and a float defining a stem. The pivot pin is movably located on the stem with the sealing element located apart from the float. The float contacts a portion of the sealing element during a refilling condition, and the sealing element seals the nozzle to prevent overfilling the fuel tank. The orifices permit the valve assembly to reopen in stages.

Abstract: A low permeation weldable fuel tank assembly is provided to reduce fuel vapor mountable to the fuel tank. The weldable fuel tank assembly has a mounting portion mountable to the fuel tank and a valve housing that is attachable to the mounting portion. In one aspect, the mounting portion includes a fuel vapor permeation barrier. In another aspect, an anti-permeation cap with a fuel vapor permeation barrier is affixed to a portion of tank assembly.

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.

Abstract: A vapor recovery fuel system includes a fuel tank having at least one vent opening defined therein. A fuel vapor canister is in communication with the vent opening to receive and filter fuel vapors from the tank. A refueling control valve is configured in the vent opening and has a first inlet orifice and an outlet in communication with the vapor trap. The control valve includes a variably buoyant first float body extending into an interior of the fuel tank which rises over a predetermined range of movement in response to increasing fuel level. The control valve includes a second float body engaged by the first float body over at least a portion of its range of movement. The first float body has a buoyancy during refueling so as to rise with increasing fuel level to engage and move the second float body into a sealing position to seal the inlet orifice from the outlet at a predetermined height of fuel within the tank.
