Abstract: A fuel filler device for filling fuel into a vehicle tank, includes a filler pipe for receiving a fuel filler nozzle, which filler pipe can be connected with the vehicle tank. At least one pivotably mounted closing flap is arranged in the filler pipe. A spring element is provided, which biases the at least one closing flap into a closing position closing a passage through the filler pipe. The at least one closing flap is pivotable from the closing position into an opening position opening a passage through the filler pipe as a result of the fuel filler nozzle inserted into the filler pipe. At least one valve element forms at least one bypass to the at least one closing flap, and from a limit pressure difference, allows a passage of gas out of the filler pipe and/or into the filler pipe.

Abstract: The invention relates to a fuel filler device for filling fuel into a vehicle tank, comprising a filler pipe for receiving a fuel filler nozzle, which filler pipe can be connected with the vehicle tank, wherein at least one pivotably mounted closing flap is arranged in the filler pipe, wherein a spring element is provided, which biases the at least one closing flap into a closing position closing a passage through the filler pipe, wherein the at least one closing flap is pivotable from its closing position into an opening position opening a passage through the filler pipe, by the fuel filler nozzle inserted into the filler pipe, wherein at least one valve element is provided in the filler pipe, which valve element forms at least one bypass to the at least one closing flap and, from a limit pressure difference, allows a passage of gas out of the filler pipe and/or into the filler pipe.

Abstract: The invention relates to a fuel filler device for filling fuel into a vehicle tank, comprising a filler pipe for receiving a fuel filler nozzle, which filler pipe can be connected with the vehicle tank, wherein, in the filler pipe, a first pivotably mounted closing flap and at least a second pivotably mounted closing flap are provided behind one another as seen in the insertion direction of the fuel filler nozzle, wherein the first and at least one second closing flap can be pivoted from a closing position, closing a passage through the filler pipe, into an opening position, opening a passage through the filler pipe, by the fuel filler nozzle inserted into the filler pipe, wherein the first and at least one second closing flap are coupled with one another and/or provided such that, when the first closing flap is pivoted into its opening position, the at least one second closing flap is also pivoted at least partially into its opening position, wherein the at least one second closing flap is held in its at lea

Abstract: The filling end piece comprises a duct having an insertion aperture and a sleeve moveable with respect to the duct. The sleeve is adapted to adopt a withdrawn position when not urged and an advanced position when it is urged by a movement of insertion of a spout of large diameter. The end piece comprises an obstacle for countering the filling by a small spout. The end piece comprises an end of travel abutment for a small spout, fixed with respect to the duct and projecting inwardly, the abutment being distinct from and upstream of the obstacle in the duct.

Abstract: The head for a filler pipe of a vehicle tank provided with an obturating assembly includes: a body having a passage aperture; and an obturator pivoting relative to the body between an obturating position and a freeing position. The obturator is elastically biased towards the obturating position by a spring. The obturator includes a seal disposed in the obturating position between the obturator and a sealing seat that the body comprises. The head includes a hinge to pivotally mount the obturator on the body. The relative positioning between the seat and the pivotal axis defined by the hinge is fixed. The seat is flat and the obturator includes a plug provided with the seal and a flap mounted on the body by the hinge and biased by the spring with the plug which is mounted on the flap by virtue of a ball joint.

Abstract: An obturating assembly includes a body having an aperture for passage to the pipe of a fuel supply spout of predetermined outer diameter and an obturator that is moveable with respect to the body. In accordance with the invention, the head further includes an access assembly having a shell through which the spout must pass before reaching the obturator, the shell having a plurality of flexible tabs generally forming an assembly of funnel shape of which the minor diameter is less than the outer diameter of the spout and of which the major diameter is greater than the outer diameter of the spout.

Abstract: The head for a fuel filler pipe of a vehicle tank provided with an obturating assembly comprises: a body having a passage aperture; and an obturator pivoting relative to said body between an obturating position and a freeing position, said obturator being elastically biased towards said obturating position by spring means, said obturator comprising a seal disposed, in said obturating position between said obturator and a sealing seat that said body comprises, said head comprising a hinge to pivotally mount said obturator on said body. The relative positioning between said seat and the pivotal axis defined by said hinge is fixed, said seat being flat and said obturator comprising a plug provided with said seal and a flap mounted on said body by means of said hinge and biased by said spring means with said plug which is mounted on said flap by virtue of ball joint means.

Abstract: An obturating assembly includes a body having an aperture for passage to the pipe of a fuel supply spout of predetermined outer diameter and an obturator moveable with respect to the body, able to assume an obturating position in which it conceals the passage aperture and a freeing position in which it does not conceal it, the obturator being driven towards the freeing position by that spout when it meets the obturator during a thrusting movement of the spout into the head. In accordance with the invention, the passage aperture is provided in an oblique wall or wall portion, with the angular offset between the orientation of said obturator in the obturating position and the transverse orientation being at least equal to 20°.
