The closure unit includes an inner portion that remains coupled to a filler neck to block discharge of liquid fuel and fuel vapor from the filler neck and an outer portion that takes the blow and separates from the inner portion at the fracture line.

Breakaway closure for capless tank filler neck

A filler neck closure assembly () includes a closure apparatus () formed to include a pump nozzle-receiving opening () and adapted to be mounted on an open mouth of a filler neck. A cover, pivotally mounted to the closure apparatus (), is movable between a first position covering the nozzle-receiving opening () to seal the filler neck () and a second position uncovering the nozzle-receiving opening () to allow access thereto. An overcenter leaf spring () normally biases the cover () toward its first closed position. A tether () coupled to the cover () has its other end () coupled to a filler neck access door () so that as the access door () is moved from a closed position blocking access to the filler neck () to an open position unblocking access to the filler neck (), the cover () is moved from the first position covering the nozzle-receiving opening () to the second position uncovering the nozzle-receiving opening ().

Closure door system for vehicle filler neck

A filler neck closure assembly for a vehicle fuel tank filler neck includes a filler neck closure housing adapted to be coupled to the fuel tank filler neck. The filler neck closure housing is formed to include an outer aperture sized to receive a fuel-dispensing pump nozzle therein. The assembly also includes a dust shield mounted for movement relative to the filler neck closure housing to open and close the outer aperture of the filler neck closure housing. A lock of the assembly is coupled to the filler neck closure housing and is movable between a locked position to prevent the dust shield from opening the outer aperture and an unlocked position to allow the dust shield to open the outer aperture.

Dust cover lock system for vehicle filler neck

A filler neck closure assembly includes a nozzle receiver associated with a vehicle fuel tank and a fuel-discharge control collar adapted to receive therein a fuel-dispensing pump nozzle inserted into the nozzle receiver during fuel tank refueling.

Floating nozzle collar for capless filler neck

A redundant seal for a vehicle fuel tank filler neck closure is provided for closing and opening an automobile fuel tank to the atmosphere. The redundant seal ( ) includes a lower shoulder ( ) which sealably engages a first valve seat and an upper shoulder ( ) which sealably engages a second valve seat. The redundant seal ( ) is appropriate for use in applications such as filler neck closures, pressure and vacuum-relief systems within tank filler neck closures, and capless filler neck closure systems.

Redundant seal for tank filler neck closure

A filler neck closure assembly ( ) includes a closure apparatus ( ) formed to include a pump nozzle-receiving opening ( ) and adapted to be mounted on an open mouth of a filler neck A cover pivotally mounted to the closure apparatus ( ), is movable between a first position covering the nozzle-receiving opening ( ) to seal the filler neck ( ) and a second position uncovering the nozzle-receiving opening ( ) to allow access thereto. An overcenter leaf spring ( ) normally biases the cover ( ) toward its first closed position. A tether ( ) coupled to the cover ( ) has its other end ( ) coupled to a filler neck access door ( ) so that as the access door ( ) is moved from a closed position blocking access to the filler neck ( ) to an open position unblocking access to the filler neck ( ), the cover ( ) is moved from the first position covering the nozzle-receiving opening ( ) to the second position uncovering the nozzle-receiving opening ( ).

Contaminant cover for tank filler neck closure assembly

A filler neck includes a housing adapted to be coupled to a fuel-delivery conduit coupled to a fuel tank inlet of a vehicle fuel tank. The housing includes a passageway that defines an axis of the filler neck and is adapted to receive a pump nozzle. The filler neck further includes a shuttle positioned for movement in the passageway along the axis between a closed position to close the passageway and an opened position to open the passageway in response to engagement with the pump nozzle

Filler neck for a fuel system

A filler neck closure assembly ( ) includes a housing ( ) formed to include a passage ( ), a tank pressure control assembly ( ) in passage ( ), and an outer shell ( ) coupled to housing ( ). Closure assembly ( ) includes a sleeve ( ) that reinforces housing ( ) and shields tank pressure control assembly ( ). Closure assembly ( ) also includes a sealing gasket ( ) and a foam ring ( ) between housing ( ) and a side wall ( ) of outer shell ( ) leakage of fuel vapor therebetween. Outer shell ( ) includes frangible tabs ( ) that break away from the rest of outer shell ( ) in a controlled manner when outer shell ( ) is subjected to an impact during a vehicle crash. Outer shell ( ) is formed to include a fluid drain ( ) and closure assembly ( ) includes a float ( ) that closes fluid drain ( ) and that moves to open fluid drain ( ) to allow accumulated fluid to drain out of outer shell ( ).

Seal for filler neck closure assembly

An apparatus for use with a filler neck of a vehicle includes a filler neck access door adapted to be coupled to a side wall of the vehicle, a filler neck closure that is adapted to be coupled to an open mouth of the filler neck to close the open mouth and includes a first seal configured to block fuel and fuel vapor from flowing from the filler neck to atmosphere, and a cover configured to cover the filler neck closure upon closure of the filler neck access door. The cover includes a second seal and a seal support coupled to the second seal and the filler neck access door. The seal support yieldably biases the second seal into engagement with the filler neck closure upon closure of the filler neck access door.

Spring-loaded contaminant cover for tank filler neck closure assembly

A filler neck closure assembly (,) includes a closure apparatus (,) formed to include a pump nozzle-receiving opening (,) and adapted to be mounted on an open mouth of a filler neck (,). A cover (,), pivotally mounted to the closure apparatus (,), is movable between a first position covering the nozzle-receiving opening (,) to seal the filler neck (,) and a second position uncovering the nozzle-receiving opening (,) to allow access thereto. An overcenter leaf spring (,) normally biases the cover (,) toward its first closed position. A tether (,) coupled to the cover (,) has its other end (,) coupled to a filler neck access door (,) so that as the access door (,) is moved from a closed position blocking access to the filler neck (,) to an open position unblocking access to the filler neck (,), the cover (,) is moved from the first position covering the nozzle-receiving opening (,) to the second position uncovering the nozzle-receiving opening (,).

Contaminant cover for tank filler neck closure

An apparatus is provided that includes a valve assembly and a retainer that couples the valve assembly in a fuel tank. The valve assembly includes a housing having a body portion, a flange coupled to the body portion and retainer blocks extending from the body portion spaced-apart from the flange. A valve is positioned to lie in the housing. The retainer is adapted to be coupled to an exterior surface of the tank. The retainer includes a body portion that defines a passageway sized to receive the body portion of the housing and a ring coupled to the body portion of the retainer and formed to extend into the passageway. The flange and retainer blocks cooperate with the body portion of the retainer and ring to couple the valve assembly and retainer together.

Weldable fuel tank valve apparatus

An apparatus for mounting a vent valve assembly in an aperture of a fuel tank comprising a valve assembly including a housing having a body portion and a flange coupled to the body portion and with a retainer block extending from the body portion spaced-apart from the flange and with a valve positioned to lie in the housing. A retainer is adapted to be coupled to an exterior surface of the fuel tank including a body portion defining a passageway being sized to receive the body portion of the housing therein and a seat formed integrally with the body portion of the retainer and extending into the passageway, so that the flange and the retainer block can cooperate with the seat to couple the valve assembly and retainer together.
