When it is refilled, the lid is removed from the filling inlet and placed on a convenient support surface; and, sometimes, since the vehicle was refilled, the lid can be improperly placed and the fuel filling inlet can be left unnoticed, or you can forget to put the lid on, which gives result in an extremely dangerous spread of fuel or its vapors. It is an object of the present invention to provide a fuel filling assembly designed to solve the aforementioned of the known fuel filling inlets, and more specifically to provide a filling inlet assembly wherein the lid can not be separated or removed from the assembly when the inlet for filling is opened. According to the present invention, there is provided a fuel filling assembly, particularly for a motor vehicle, comprising a filling inlet that is connected to the supply pipe of a tank; a lid to close the inlet for filling; a receptacle internally defining a compartment for receiving the filling inlet and a lid; a lid for closing the articulated compartment on one side of the receptacle; and mechanisms for snapping the lid in its closed position; characterized in that the assembly also comprises the articulated connection mechanisms for connecting the cover at the entrance, and which is provided to keep the cover connected to the entrance in any open position of the cover, and to place the cover in front of the entrance for filling when the lid is in its closed position, to close the inlet for filling in a leak-proof manner of fuel.

A preferred embodiment, but from no limiting point of view, of the present invention will be described by way of example, with reference to the accompanying drawings, which: Figure 1 shows a longitudinal section from the upper part of the assembly of entry for filling according to the present invention; Figure 2 shows a longitudinal section of the portion connecting Figure 1 den filling inlet assembly to a pipe for supply of a tank; Figure 3 shows a longitudinal section from the top of a variation of Figure 1 of the filling assembly; Figure 4 shows an isolated detail of Figure 3 of the filling assembly. With reference to Figures 1 and 2, the filling assembly 1 according to the invention comprises a substantially circular filling inlet 2 defined at one end by means of a circular inlet 4 for receiving the fuel leakage-proof cover 6; at the opposite end of the entrance 4, the filling inlet 2 is connected to the supply pipe 8 of the tank that is not shown; and a tube 8 is externally positioned and integrated into the filling inlet 2 by means of a number of peripheral teeth 9 projecting from the periphery of the inlet for filling 2 and fitting (at close a "click" is heard) within the respective closure openings 10 formed in the tube 8. At the end of the inlet 4, the portion 11 of the inlet for filling "", projects into the compartment 12 defined by means of a receptacle 14 and sized to also accommodate the lid 6 when it is placed in the closed position in the filling inlet 2, the receptacle 14, which is preferably made of plastic, is a depression in the interior of the body of the vehicle 15, and the receptacle 14 comprises a lid 16 hinged to a pin 17 integrated in the side wall 18 of the receptacle.The lid 16 is designed to rotate, at a maximum angle of approximately 90 °, from the closed position 19. to an open position 20 (shown by the dotted line in Figure 1), the lid 16 is held in the closed position 19 by means of a spring M acting between the wall 18 and the support arm 21 of the cover 16: lid 16 is closed in closed position 19 by means of snap-fastening mechanisms 22 defined by a bolt 23 sliding in the respective support 24 fixed in receptacle 14; the pin 23 is pushed by means of a contrast spring 25 so that it is fixed (upon hearing a "click") within a stop tooth 251 placed on the cover 16, and withdrawn in opposition to the contrast spring 25 for releasing the lid 16 by, for example, a cable (not shown) controlled from a remote part of the vehicle, by example from the passenger cabin. The assembly of the inlet for the filling 1 according to the invention also comprises the connection mechanisms 26 for connecting the cover 8 to the inlet 16 and which is defined by a support 27 placed on the internal wall of the cover 16 and which engages the corresponding connecting member 28 together with the cover 6. In the preferred embodiment shown, the support 27 comprises a recessed contact surface 29 defined internally by means of a hemispherical surface 30 and within which it is hooked or closed with a click, a spherical head 31 integrated to the lid 6 and forming part of the connecting member 28. The spherical head 31 is attached to the lid 6 by means of a base body 32, and engages the recessed contact surface 29 with a small gap that allows the lid 6 to move freely and adapt in any direction within the defined angular limits by contacting the body of the base 32 with the circular edge 3 3 defining the recessed contact surface 29. The support 27 is thus placed on the inner face of the lid 16 in such a way that it places the lid 6 against the inlet 4 with sufficient pressure to ensure a leak-proof seal of fuel when the cover 16 is placed in its closed position 19. The cover 6 comprises an annular contact surface 34 which is made of an elastomeric material, such as a soft rubber, having a radial section in the form of a double V, and sufficiently tacit or flexible in any direction to ensure that the cap 6 correctly fits the coupling front edge. in the inlet 4. The cover 6 comprises a cylindrical central stop body 38 longer than the front edge 35 of the inlet 4 and having an annular contact surface 39 for the seal 34; one side of the central body 38 is integrally joined with the spherical head 31 by a base body 32; and the opposite side is fixed to the body of a known valve 40 for venting fuel vapors from the tank. When the lid 16 is closed, the lid 6 of the filling assembly 1 according to the present invention is thus automatically pressed against the connecting edge 35 of the inlet 4 to ensure perfect closing of the inlet for filling 2, thanks to the ability to adapt the seal 34, and the freedom of movement provided by the spherical connection of the head 31 within the recessed contact surface 29. The entry for the filling 2 can be fixed on the inside with an auxiliary structure 42 comprising a reduction element 43 for reducing the useful section, and a check valve 44 for retaining the fuel vapors; the auxiliary structure 42 is made in a way integral with the filler 2 by means of an elastic retaining tab 45, which engages, upon a "click", within the respective openings in the filler 2; the reduction element 43 (FIG. 2) comprises a tubular segment 46 bevelled or reduced to a diameter smaller than that of the inlet for filling 2, and for receiving a device for delivery (not shown) for a particular fuel, for example, unleaded gasoline; the check valve 44 comprises a tongue or projection 47 hinged to the auxiliary structure 42, normally closed by means of a spring (not shown) and which is opened by the insertion of a supply device inside the inlet for filling 2; the tab 47 prevents fuel vapors from escaping when the lid 6 is opened, and when the supply device is inserted, the vapors are recovered by the device itself. Figures 3 and 4, in which any detail similar or identical to those already described are indicated using the same numerical system, show a variation of the filling assembly according to the invention. The filling assembly la is substantially similar to the assembly 1 that was described with reference to Figures 1 and 2, and differs substantially in relation to the configuration of the locking mechanisms that are fixed at pressure 22 of the lid 16, which in this case they act directly on the cover 6 in opposition with the lid 16. In particular, the closing mechanisms 22 comprises a jaw 50, which slides inside the contact surface 51 extending essentially through the side wall 52 of the receptacle 14, and is activated by means of the remote device known that it is not shown. The jaw 50 is defined by two articulated elements 53, 54 and comprises three rounded retaining teeth 55, 56, 57 arranged, for example, in the form of an equilateral triangle. The two articulated elements 53, 54 are driven towards each other by means of a spring 58 placed in the articulated joint between the elements 53, 54. The cover 6 comprises an annular groove 59 having contact surfaces 60, 61, 62 for the insertion, which snaps, of the respective retaining teeth 55, 56, 57. Similarly to the filling assembly 1, the lid 6 has an annular contact surface 34 made of an elastomeric material and having, for example, a circular radial section. However, unlike the previous case, the seal 34 is fixed to an end portion 63 of the lid 6, smaller than the front edge 35 of the inlet 4; and at front edge 35 comprises an annular contact surface 64 on which contact surface 34 rests when the end portion 63 of the lid 6 is inserted inside the inlet 4, such that, when the lid 16 closes, the lid 6 hermetically seals the inlet for filling 2 the lid 6, and consequently also the lid 16 connected thereto by an articulated mechanism 26, is maintained in the closed position by the jaw 50, the retaining teeth 55, 56, 57 which engage the respective contact surfaces 60, 61, 62. When the control device (not shown) of the jaw 50 is activated, the jaw 50 is separated and partially withdrawn in relation to the closed position in such a way that the teeth 55, 56, 57 - also by virtue of their round shape - are released from the respective contact surfaces 60, 61, 62; thus the jaw 50 moves in the position shown by means of the dotted line in the Figure 4, wherein the lid 6 is released from the jaw, and therefore the lid 16 is opened by the spring M and by means of the elastic reaction of the seal 34 against the front edge 35 of the inlet 4. , when the lid 16 is closed, the lid 6 engages, producing a "click" sound, between the two elements 53, 54 of the jaw 50, which are forced open until they are actuated together by means of a spring 58 around from slot 59; the teeth 55, 56, 57 engage the respective contact surfaces 60, 61, 62 to close the cover 6 and cover 16, connected to cover 6, in the closed position; and the particular arrangement (three points) of the teeth provided for a greater balance, and therefore safety, effectiveness, closure still < »The case of severe external stress (impact). The spring 58 is preferably such that the gripping force exerted by the jaw 50 on the lid 6 is greater than the force required to break the articulated connection 26 between the lid 6 and the cover 16. therefore, in the event of a collision, even if the cover 16 were opened accidentally, the cover 16 would be separated from the cover, which would remain in the closed position preventing any leakage of fuel from the tank. Of course, the snap locking mechanisms 22 may comprise a combination of the two devices described above, to act on both the cover 6 and the cover 16. Clearly, changes can be made to the filling assembly that was described and it was illustrated in the present and, however, would not depart from the scope of the present invention, in accordance with what is claimed therein. For example, the articulated mechanisms (26) for connecting the cover (6) to the cover (16) can be defined by means of a simple elastic flexible elements connected to both the cover (6) and the cover (16).
