A filler neck closure unit includes a frangible portion that is configured to break along a fracture line when an outer portion of the closure unit is hit by a strong blow. 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 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

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 closure assembly includes a filler neck, a housing, and an appearance cover. The housing includes a nozzle-receiving passageway and an interior region. A closure door is coupled to housing and prevents fuel vapor from flowing through passageway. A pressure-relief valve assembly is positioned within interior region and controls the flow of fuel vapor through interior region when the closure door is closed. A valve actuator is coupled to housing and includes a nozzle arm, a stem arm, and a conductor arm. Stem arm moves with nozzle arm and opens pressure-relief valve assembly when nozzle arm is engaged by a fuel-dispensing nozzle upon movement of a nozzle into passageway. A conductor arm is coupled to nozzle arm and is positioned to contact filler neck through an opening in housing. When a nozzle contacts the nozzle arm, any electrical charge present on the fuel-dispensing nozzle is conducted through nozzle arm and conductor arm to the filler neck.

Filler neck closure assembly

A fuel tank filler apparatus includes a fuel tank filler neck, a pressure-relief valve coupled to the fuel tank filler neck, and a filler neck closure coupled to the fuel tank filler neck. The filler neck closure includes a drainage basin configured to collect liquid fuel, a retention chamber configured to store liquid fuel, and a fuel conductor configured to communicate liquid fuel between the drainage basin and the retention chamber. The filler neck closure can also include a blocker positioned to pivot about a pivot axis between a normally closed position blocking a fuel-receiving passage and an opened position permitting liquid fuel to flow through the fuel-receiving passage to the fuel tank.
