A connector includes a resin-made connector body and a pressure sensor. The connector body includes a first main tubular part that is connected to a first pipe, a second main tubular part that is connected to a second pipe, and a sensor mounting part. The first main tubular part and the second main tubular part connect with each other to form an angle. The sensor mounting part includes: a tubular intake part that is formed in line with a line extending from one of the first main tubular part and the second main tubular part and has a bottom face; and a sensor mounting seat that is capable of being mounted with the pressure sensor and communicates with a peripheral-surface opening of the tubular intake part.

The present invention discloses a filling device (1) for a motor vehicle operating fluid container (3). The filling device (1) comprises a mouth hole connection piece (11), into which a dispensing valve (40) can be introduced in order to fill the operating fluid container (3). The filling device (1) further comprises a compensation chamber (24) to which the mouth hole connection piece (11) is connected in fluid terms. A connection piece (21) of the filling device (1) is arranged between the operating fluid container (3) and the compensation chamber (24) and is connected in fluid terms to the operating fluid container (3) and the compensation chamber (24). The filling device (1) is distinguished in that the connection piece (21) protrudes into the compensation chamber (24), the connection piece (21) is arranged so as to face the mouth hole connection piece (11) and to be spaced apart therefrom, the connection piece (21) is surrounded by the compensation chamber (24), and a dispensing valve (40) can be introduced through the mouth hole connection piece (11) into the connection piece (21).

An inter-flap space 36 between an outside flap 24 and an inside flap 44 of a filler pipe 16 is placed in communication with the inside of a fuel tank 14 using a communication pipe 62, and an open and close valve 64 is provided to the communication pipe 62. Further provided are a pressure reduction pump 82 that depressurizes the fuel tank 14, an internal tank pressure sensor 68 that detects an internal tank pressure of the fuel tank 14, and a controller that controls opening and closing of the open and close valve 64 and driving of the pressure reduction pump 82, and that determines an outside flap seal state of the outside flap 24 based on the internal tank pressure.

A tank filler tube includes a fill tube line which features, in the tank assembled state, an inlet end further from the tank, which is designed for temporary insertion of the fill nozzle into a closer-to-the-tank insertion region of the fill tube line, and with a closer-to-the-tank transit line end in the tank assembled state, which is designed for transit of liquid in a direction of the liquid transit line leading away from the inlet end, wherein the fill tube line is of multi-part design. At least one part of the ventilation line is for venting the gas displaced during a filling of a tank into the atmosphere. The fill tube line section featuring the transit line end extends into the insertion region further from the tank and is designed to accommodate at least one outlet end of a fill nozzle during a filling of a tank.

A venting system for a filler pipe coupled to a diesel exhaust fluid tank in a vehicle is provided. In one example approach the venting system comprises a plurality of cut-outs in an interior surface of the filler pipe along the interior diameter of the filler pipe in a top surface of the filler pipe.

The resinous filler port includes: a filler-port body including a nozzle insertion port through which a filler nozzle is insertable, a fuel supply port supplying a fuel supplied from the filler nozzle to a fuel tank by way of a filler tube, and a vapor inlet port letting flow in vapors arising from the fuel and passing through a breather tube from a side of the fuel tank; a joint formed to penetrate through from one of opposite ends thereof to another one of the opposite ends, fitted undetachably into and around the vapor inlet port at the one of the opposite ends, and connected with the breather tube at the other one of the opposite ends; and a flow control valve accommodated inside the joint, and controlling a flow volume of the vapors flowing into the filler-port body from the breather tube.

An operating medium tank arrangement for a motor vehicle includes an operating medium tank; a filling tube for refueling the operating medium tank, wherein the filling tube is fluidly connected on one side to the operating medium tank and on the other side has an insertion opening for receiving a refueling device; a guide insert arranged in the filling tube for guiding the refueling device; and a liquid separator including a separator chamber which is divided into a first sub-chamber and a second sub-chamber, wherein the first sub-chamber is fluidly connected to the operating medium tank via a ventilation line, wherein the second sub-chamber is fluidly connected to a filter device, wherein the separator chamber is fluidly connected to the filling tube for purging operating medium separated in the liquid separator into the filling tube, and wherein the first sub-chamber and the second sub-chamber are fluidly connected with each other via a labyrinth separator which is formed by the liquid separator and the filling tube.

The present invention relates to a filler head (100) for a liquid tank in a motor vehicle with a housing (103), with a first molded housing part (103-1) having formed therein a tank vent pipe (105) for introducing air into the housing (103); and a second molded housing part (103-2) having formed therein a dip tube (107) for guiding a jet of liquid in the interior of the filler head (100), the dip tube (107) including a vent opening (111) for discharging from the filler head (100) the air that may be introduced through the tank vent pipe (105).
