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.

A filler neck (1) for filling an operating substance, such as fuel or AdBlue or urea, or an additive, such as water, into a vehicle tank by way of a fuel pump nozzle. The filler neck (1) has a filler neck body (2), which can be accommodated in a filler pipe leading to the vehicle tank. The filler neck (1) furthermore has a fuel pump nozzle guide with an insertion section (4) for guiding a fuel pump nozzle, which is accommodated or is to be accommodated in the filler neck body (2), in the direction of the vehicle tank. The filler neck body (2) and the insertion section (4) of the fuel pump nozzle guide are formed together as an integral casting, in particular plastics injection moulding.

A capless fuel door assembly including a body pivotally supported within a housing of the vehicle between closed and opened positions. The body includes an exterior projection exhibiting an angled slide. A spring is secured to the housing and includes an extended portion supported against an end stop location of the projection defining a first end of said angled slide in order to exert the body in the closed position, with opening of the body about the pivot causing a decrease in the closing force as the spring portion displaces along said angled slide to a second end to achieve the opened position.

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 capless filler pipe closure is provided for a tank filler pipe. The capless closure permits a fuel pump nozzle to be inserted into the tank filler pipe without first removing a fuel cap from the outer end of the tank filler pipe.

A filling head (12) for a fuel tank, particularly of a vehicle, the head including a tubular sleeve (16) of which a first longitudinal end (16a) defines a filling opening and of which a second longitudinal end (16b) is intended to be fixed to one end (14a) of a fuel pipe (14). The head further includes a ring (18) mounted in the sleeve and having a passage orifice for a filling nozzle, wherein the sleeve is made of HDPE and its second end is intended to be fixed by welding to the end of the fuel pipe. An annular seal (36) is mounted between the ring and the sleeve near the second end.

The invention relates to a coupling for cryogenic liquefied media, said coupling comprising a coupling socket (10) and a coupling connector (30), which can be connected thereto, each being equipped with a non-return valve (15, 40). According to the invention, the coupling socket (10) comprises a front section (11), having means for connecting to the coupling connector (30), and a rear section (12), having the non-return valve (15). According to the invention, the front section (11) is connected to the rear section (12) by means of screws (33) having predetermined breaking points, which break upon exceeding a specified tensile stress. According to the invention, the sections (11, 12) separate from each other and the non-return valves (15, 40) automatically move to the closed position.

A fuel fill opening structure for a fuel tank includes a fuel filler pipe, a fuel fill opening, and a flow guide. The flow guide includes a main guide wall which partitions a fuel introduction region inside the fuel filler pipe into an upper space communicating with a tank main body side and a lower space communicating with the fuel fill opening side, and a partition wall provided to be continuous with the main guide wall and configured to close a space between an upper surface side of the main guide wall and an inner surface of the fuel filler pipe. The main guide wall includes a bent inclined part that is bent and inclined downward from a middle portion in running from the fuel fill opening side toward the tank main body side. The bent inclined part has a shape in which a width thereof becomes smaller when viewed from above as it inclines downward.

A channel forming member is attached to a filler neck on a nozzle insertion side where a fueling nozzle is to be inserted. The channel forming member includes a barrier section that forms an insertion flow path section for the fueling nozzle in the fuel flow path on the nozzle insertion side, while forming an annular channel surrounding the insertion flow path section so as to separate the channel from the insertion flow path section. The channel forming member further includes the following provided to the barrier section: an atmosphere communication hole for making the channel communicate with the atmosphere; a flow path communication hole for making the channel communicate with an insertion end flow path section downstream from the insertion flow path section; and a valve mechanism that prevents passage of the atmosphere through the channel in a fueling period. This contributes to reduction in introduction of the atmosphere into the fuel flow path through the channel in a fueling period.
