The present disclosure relates to an energy replenishment port assembly, comprising: a housing seal made of an elastic material; a housing having an installation port, the housing seal being arranged around an edge of the installation port and extending from a reverse side of the edge of the installation port; and a receiving port component comprising a receiving port, the receiving port component being detachably installed on the installation port. The housing seal is configured to being pressed against a vehicle body to sealingly install the housing onto the vehicle body. The receiving port is configured to receive an energy replenishment connector.

A filler and/or charger flap liner (3) is provided with a seal arrangement. The filler and/or charger flap liner (3) is to be arranged in an opening (6) of an outer side part (4) and in an opening (7) of an outer wheel arch (5). The filler and/or charger flap liner (3) is to be arranged with a first bearing element (8) on an edge of the opening (6) of the outer side part (4) and is to be arranged with a second bearing element (9) on an edge of the opening (7) of the outer wheel arch (5). An at least partially circumferential sealing element (10) is arranged radially outside the openings (6, 7) of the outer side part (4) and the outer wheel arch (5).

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).

A refueling coupling has an annular fitting 101 having a bore 102, bayonet lugs 103 and slots 104 suiting it for connection to a pressure filling nozzle. A flange 122, drilled with screw holes for securement to a fuel tank (not shown), extends out from the fitting 101. Also not shown for the sake of clarity is a tube extending own from the flange. Rods extend down from the flange 122 to a spider 125, with springs bearing upwards onto the underside of a dry-break member 105, through which the rods extend. The rods, springs and spider are within the non-shown tube. On attaching and opening of a pressure filling nozzle to the coupling, the dry-break member 105 is displaced resiliently inwards fuel can flow past this member and into the tank. The dry-break member has a central aperture 111, normally closed by a plug 112, which is threaded externally 114 and carries an O-ring seal 115 above the thread. The central aperture has a plain bore orifice 116 and is threaded 117 below the plain bore. Thus, when the plug is screwed in, the dry-break member is fluid tight as normal.

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.

There is provided a fuel supply device comprising a filler neck body provided in a tubular shape to include an opening which a fueling gun is inserted in and a connection port formed on a fuel tank-side end of the filler neck body and configured to form a fuel passage; and a neck integrated component located on an inner side of the filler neck body and configured to form an insertion passage. The neck integrated component is arranged to engage with inside of the filler neck body on a fuel tank side or with a fuel tank-side end of the filler neck body. This configuration suppresses a fueling gun from being stuck during insertion and reduces the possibility that the engagement part of the filler neck body and the neck integrated component is damaged.

A filling head for filling a tank with a liquid, the filling head delimiting a conduit for filling the tank which extends axially along a filling axis from an upstream section which is adapted to receive a filling nozzle, up to a downstream section which is designed to be connected on the tank to fill, and a degassing circuit including an inlet which is adapted to be connected on the tank and an outlet in communication with the outside, the filling head being characterized in that it delimits a suction window which connects the downstream section of the filling conduit on the degassing circuit, so as to promote the suction of the gases via the degassing circuit, during the filling of the tank.

A fuel filler structure capable of use with a fuel feeding pipe prevents efficiency of sucking volatile fuel from being decreased during refueling even if a drain hole is formed, and includes: a cylinder that includes an opening and a connecting port; a first flap mechanism that is arranged near the opening of the cylinder and opens the opening when a nozzle is inserted; a drain hole that is formed in the cylinder and communicates inside the cylinder with outside; and a drain hole switching valve that opens and closes the drain hole, wherein the drain hole switching valve has a closing mechanism including a valve body that is pressed by the nozzle when the nozzle is inserted through the opening, so that the drain hole is closed.

A capless ORVR system providing sealing and reducing hydrocarbon outlet and having a wave seal, a primary flapper, and a secondary flapper for preventing outlet of hydrocarbons by means of surrounding the nozzle while the nozzle is being placed, allowing uni-directional flow to continue and preventing backflow when there is pressure in the opposite direction from within, and allowing the fuel to exit through the filler neck by being bent outwards.

A fuel tank filler apparatus comprises a capless filler neck closure adapted to be mated with an outer end of a fuel-tank filler neck. The capless filler neck closure may be removable from the fuel-tank filler neck for service or repair.
