The filler neck is formed to have an outlet inside diameter being larger than the predetermined inside diameter in the minor-diameter cylindrical portion of the filler tube.

A filler neck housing arrangement for mounting on a body opening of a motor vehicle includes a housing body (12) which forms a passage opening for the insertion of at least one tank filler pipe. An annular sealing and holding body (10) is configured for holding the sealing and holding body on the body opening and for holding the sealing and holding body on the housing body. The sealing and holding body includes a first sealing member which, in the state of the sealing and holding body being held on the body opening, lies in a sealing manner against a surface (30) of a body part (28) bounding the body opening, and a second sealing member which, in the state of the sealing and holding body being held on the housing body, lies in a sealing manner against the housing body (12).

The invention relates to a filler neck (1) for a fuel tank of a motor vehicle having at least one tubular section (3) provided in the region of the filler inlet (2) in order to receive the outlet pipe of a fuel delivery nozzle (5), and a flame barrier (4) which is provided in the tubular section (3) and surrounds the outlet pipe of the fuel delivery nozzle (5) in the inserted state, wherein the flame barrier (4) includes at least two segments (6) which are mounted resiliently in the radial direction of the tubular section (3), the diameter of the opening (7) in the flame barrier (4) for the outlet pipe of the fuel delivery nozzle (5) being smaller in the prestressed state of the segments (6) than the diameter of the outlet pipe of the fuel delivery nozzle (5).

A fuel-tank filler apparatus includes a fuel-tank filler neck and a filler neck closure. A flapper door is provided to control access to a fuel-conducting passageway formed in the fuel-tank filler neck.

Filler neck, including a passage extending along a longitudinal axis, at least one permanently magnetic element being arranged annularly around the longitudinal axis, at least in regions, outside the passage and able to generate a permanent magnetic field in the passage, and either at least one ferromagnetic element arranged annularly around the longitudinal axis, at least in regions, outside the passage, the at least one permanently magnetic element and the at least one ferromagnetic element being arranged so as to be adjacent and so as to overlap, at least in regions, viewed in the direction of the longitudinal axis, or the at least one permanently magnetic element having a height, viewed in the direction of the longitudinal axis, that is different from 10 mm, and arranged in the filler neck such that a magnetic field generated by the at least one permanently magnetic element has a maximum attractive force, towards the longitudinal axis, in a specified position in the passage.

A fluid transfer coupling is described that includes first and second connectable coupling members that together contain a sealed interior space when connected. A gas or steam purge inlet and a purge outlet are disposed in fluid communication with the sealed interior space for purging potential contaminants out of the interior space. The coupling also includes a vacuum port in fluid communication with the sealed interior space for drawing a vacuum on the sealed interior space and optionally testing the space for an adequate seal. The first coupling member includes a first fluid transfer conduit and the second coupling member includes a second fluid transfer conduit. The first and second fluid transfer conduits are positioned such that they can be connected together within the sealed interior space when the first and second coupling members are connected.

An onboard refueling vapor recovery (ORVR) system includes a main canister, a spare canister, a hydrocarbon sensor, a grade rollover valve (GRV), a fill limit vent valve (FLVV) and a fuel vapor pipe. The GRV and the FLVV are disposed at top portion of the fuel tank, with sides of the GRV and the FLVV hermetically connected with the fuel tank and a gas inlet end of the fuel vapor pipe. The main canister and the spare canister hermetically connect with a gas outlet end of the fuel vapor pipe. The main canister communicates with an intake manifold. The hydrocarbon sensor is disposed in the main canister and electrically connected with a vehicle control unit. The hydrocarbon sensor detects hydrocarbon concentration in the main canister and transmits the detection result to the vehicle control unit. The present invention also provides an automobile having the ORVR system.

A tank filler neck for a motor vehicle, and a motor vehicle having such a tank filler neck. The tank filler neck includes a plastic tube, a filler head composed of metal to enclose the plastic tube at an end thereof, and a first seal composed of an elastomer arranged on the circumference between the plastic tube and the filler head; a first seal composed of an elastomer, and which is arranged circumferentially between the first tube and the filler head; and a first supporting ring arranged opposite to the first seal in relation to the first tube, wherein the first supporting ring has a wall thickness that is greater than a wall thickness of the filler head.

A filler neck housing or charging housing for insertion into a body opening in a motor vehicle, comprising a housing section with a first sealing section and a second sealing section, the first sealing section being provided on an outer edge, which can be inserted into the body opening, of the housing section and being designed to bear in a sealing manner on the body opening, and the second sealing section being provided on a passage opening in the housing section, into which a tank filler pipe or a plug-in charging connector can be inserted, the second sealing section being designed to bear in a sealing manner against the tank filler pipe or the plug-in charging connector.

An oil filler port of the capless oil feeder includes: an oil filler port main body made of a resin, a breather tube portion made of the resin, and a flap valve. The oil filler port main body has a tubular shape and includes a nozzle insertion port for inserting an oil filler nozzle at one end and a fuel feed port for supplying fuel to a filler tube at the other end. The breather tube portion is formed integrally on an outer side of a peripheral surface of the oil filler port main body and connected to a breather tube. The flap valve is foamed to be insertable from the fuel feed port, and is disposed inside the oil filler port main body to close the nozzle insertion port and is opened by insertion of the oil filler nozzle.
