- the object of the present invention is to provide a closure for a fuel tank of a motor vehicle of the type mentioned in the introduction, in which the closure cover can be axially fixed to the filler neck in a simpler manner in terms of movement.
- the measures according to the invention ensure that the fixing movement of the contact element in the filler neck is derived from the pushing-in movement of the push-in part into the filler neck. As a result, for example, only a simple movement is required on the robot side in order to insert and fix or to release and to apply the closure cap in the filler neck.
- the contact element is pivotably held on the plug-in part in accordance with the features of claim 2.
- the contact element is a leg spring, the pivoting movement of which is derived from the axial movement of a slide.
- the leg spring is tensioned in such a way that one leg rests against a lower edge of the filler neck and its other leg against the outside of the tappet.
- the cover part which is rigidly connected to the pivot axis of the leg spring, is actively pressed downwards and against the seat surface of the filler neck.
- the axial extension of the plunger from the insert causes the second spring leg of the leg spring to be entrained and thus causes a pivoting movement of the leg spring, which in this way is released from the filler neck. Since the leg spring is then inside the plug-in part, the entire cap can be brought out of the filler neck.
- the contact element according to the features of claim 9 is radially movable, wherein according to the feature of claims 10 and 12, either at least one radially movable bolt or a radially deflecting sealing ring or two are provided one above the other. Preferred variants and configurations for this result from the features of claim 11 or claim 13.
- the filler neck of which is additionally covered by a flap on the body side is additionally covered by a flap on the body side, as is the case with almost all of them, the features according to claim 21 are preferably provided. It is thereby achieved that when the flap is opened or closed from the outside, the closure cap can also be brought into the filler neck in a closing manner or removed from it. This can be done in many different ways, for example by an electrical, pneumatic or the like. Connection. According to the feature of claim 22, a mechanical connection in the form of a lever linkage is provided. In order to ensure so-called crash safety, the features according to claim 23 are provided. It is thereby achieved that, when the body is deformed in this area, the flap detaches from the closure cap, so that the latter remains attached to the filler neck.
- the features specified in claim 24 are provided. This also ensures that a remote-controlled locking and unlocking is possible in a simple manner for fixing or releasing the plug-in part in the filler neck.
- the metal hydride actuator actuator or the expansion element actuator is thermally activated so that the closure can be removed by the robot, and after refueling and reinserting the plug-in part in the filler neck thermally deactivated, whereby a locking takes place.
- the thermal activation can advantageously take place electrically via a thermal resistor, so that this can be handled in a very simple manner from the interior of the motor vehicle by means of a switch or from any point by means of a remote control.
- the design of the contact element and its motion loading can be done in a variety of ways.
- the movement and sealing of the contact element or its radially movable bolt can be designed according to the features of one or more of claims 25 to 28.

This also applies to the filler neck 312 provided with the apron 345, which has a corresponding bead 351 is provided.
- the exemplary embodiment of a closure 410 shown in FIGS. 5A and 5B differs from the exemplary embodiment according to FIGS. 3A and 3B in that, firstly, a rocker arm 438 is provided instead of the eccentric lever and an annular seal with a band-like elongated rectangular cross section is provided instead of the square or round ring seals in cross section . 5A, there is a radially outward bulging of the band-shaped ring seal 444 and 450. This also results in a positive connection between these sealing rings 444, 450 and the bead 451 incorporated into the apron 345 of the filler neck 412.
- the simplified closing and opening movement is reduced to an essentially purely translational movement of the closing cover and to a radial movement of one in the closing cover 511 , 611 or 711 arranged contact and locking element 520, 620 or 720.
- the radial movement of the contact and locking element 520, 620 or 720 is either in the form of the preferably axial movement of an actuator 515, 615 or 715 a thermochemical metal hydride actuator or in the form of a thermal expansion element.
- the thermal actuator 515, 615 or 715 is connected to an electrical thermal resistor which can be activated or activated with an electric current by means of a switch located in the interior of the motor vehicle or by remote control to activate the actuator.
- an actuator to open the flap 513, 613 and 713 are operated.
- the return movement of the flap by means of the servomotor is followed by the deactivation of the actuator after the closure cap has been introduced into the filler neck.
- the closure cover 511 of the closure 510 has a flat cover part 516, which is firmly connected to a smaller-diameter insertion part 517.
- the lid part 516 has on its underside a flute-like annular groove 518, in which a sealing ring 521 is inserted, with which the closure lid 511 fits tightly on a neck support 522 of the filler neck 512 in the closed position according to FIG. 6A.
- the nozzle support 522 is part of an inwardly flanged edge of the filler neck 512.
- the plug-in part 517 which is held by means of latching elements 556 so that it can be latched on the underside of the cover part 516, has two or more radial recesses 557 which are distributed over the circumference and in which contact and locking elements 520 in the form of a locking slide 558 are arranged so as to be radially movable.
- the radially outer ends of the locking slides 558 have an inclined surface 559 with which they engage in the closed state of the closure 510 under a lower curved ring edge 530 of the nozzle support 522 (FIG. 6A).
- the two locking slides 558 are connected at their radially inner ends to an articulated lever arrangement 560, the levers 561 and 562 of which are articulated on the one hand to the locking slider 558 in question and on the other hand.

- the opening and closing of the flap 513 can be achieved, for example, with the aid of a servomotor.
- Locking and releasing the closure cap 511 or its plug-in part 517 with respect to the filler neck 512 proceeds as follows:
- FIG. 6A shows the closed or closed position, in which the insertion part 517 of the closure cap 511 is locked within the filler neck 512 and axially with it, and in which the cover part 516 of the closure cap 511 lies sealingly on the neck support 522 of the filler neck 512.
- the thermal actuator 515 is in this closed position in its retracted deactivated position. If the filler neck 512 is to be opened for the automatic refueling of the motor vehicle, the thermal actuator 515 is activated by a switch in the interior of the motor vehicle or by a remote control in such a way that voltage or current is applied to the thermal resistor, not shown, so that the thermal resistor heats up and releases its heat to the thermal actuator 515, causing axial movement of its plunger 566.
- the actuating force of the thermal actuator 515 overcomes the compressive force of the compression spring 564, so that, according to FIG. 6B, the articulated lever arrangement 560 is deflected counter to the action of the compression spring 564, which results in a radial movement of the locking slides 558 inwards, which thereby results from the lower ring edge 530 the nozzle support 522 are released.
- the closure cap 511 is now loosened or free with respect to the filler neck 512. Due to the mechanical movement connection 514, with the pivoting movement of the flap 513, the closure cap 511 can be lifted out of and from the filler neck 512, so that the filler neck 512 is freely accessible for automatic robot refueling (or also for manual refueling).
- the locking of the filler neck 512 by means of the closure cap 511 takes place in the reverse manner, ie, when the flap 513 is closed, the closure cap 511 reaches and into the filler neck 512.
- the thermal actuator 515 is deactivated again, so that with the cooling of the metal hydride actuator or the expansion element decreases its actuating force, so that the compression spring 564 is able to move the articulated lever arrangement 560 and thus the locking slide 558 back into its position according to FIG. 6A.
- FIG. 7A shows an embodiment of the closure cover 611 which is similar to the embodiment of the closure cover 511 according to FIGS. 6A and 6B.

- the upper control element 667 is acted upon by the thermal actuator 615 at one end and rigidly connected to the second control element 670 at its other end.
- the locking and unlocking of the closure cap 611 within the filler neck 612 also takes place by activating and deactivating the thermal actuator 615 in such a way that the locking slides 658 are released from the nozzle support 622 with the deactivation, while with the activation of the thermal actuator 615 that shown in FIG 7A shown locking occurs. It is understood that if the thermal actuator 615 is arranged between the second actuator 670 and the bottom 665 of the plug-in part 617, or if the pairs of sliding surfaces 668, 669 and 671, 672 in the other direction (according to FIG. 7A) are inclined, the thermal actuator 615 must be deactivated in order to release the plug-in part 617 and for the locking position of the closure cap 611 in the filler neck 612.

- the design and arrangement of the ring seals 744 and 750 are such that the ring seals between the sealing cover parts 716, 775 and 717 dodge in the radial direction during their axial movement and can insert into the ring beads 751, 752 in a sealing and axially locking manner.
- the thermal actuator 715 is located between the base 765 of the insert part 717 and an intermediate base 776 of the cover part 716, which is also feasible in the embodiment according to FIG.
- the thermal actuator 715 is activated as described above, as a result of which, due to the resulting actuating forces and the actuating path, the cover part 716 and the insert part 717 are moved relative to one another or apart become. More specifically, the insertion part 717 is moved axially away from the cover part 716. This releases the axial pressure of the sealing rings 744, 750, as a result of which these sealing rings move radially back and out of the the respective ring beads 751, 752 of the neck apron 745 of the filler neck 712. In this position of the ring seals 744 and 750 (Fig. 8B) the
- Cap 711 is pulled out of filler neck 712 and removed.
- the thermal actuator 715 remains activated during this process and during the automatic or manual filling of the motor vehicle tank.
- the closing and locking of the closure cap 711 in or in the filler neck 712 is carried out in a correspondingly reverse manner: If the closure cap 711 is inserted into the filler neck 712, the thermal actuator 715 is deactivated, so that the actuating forces into the other one due to the cooling of the thermal actuating element Direction.
- the thermal actuator 715 is firmly connected both with its fixed end at the bottom 776 of the cover part 716 and with its movable adjusting plunger with the bottom 765 of the insert part 717, the insert part 717 is retracted towards the cover part 716, whereby the sealing rings 744 , 750 are squeezed and move radially into the ring beads 751 752 for locking.
- the movement of the flap 713 connected to the closure cover 711 and the aforementioned movement of the flap 713 can follow the deactivation of the thermal actuator 715 at a fixed time interval after the activation of the thermal actuator 715.
