Abstract: Disclosed is an inlet end piece for the tank inlet of a motor vehicle, having a closure insert arranged in an upper area of a pipe inlet, having a filling opening and a sealing flap which counter to the force of a closure spring by way of a gas pump nozzle is capable of being opened by pivoting, and is held in the closed state by the closure spring. The inlet end piece has an indicator means having an indicator area, wherein the indicator means in the case of a closed sealing flap is located in an inactive position in which an indicator area of the indicator means is not visible to the user, and in the case of the sealing flap being at least partially opened, the indicator means is displaced into a signal position in which the indicator area becomes visible.

Abstract: A cap-free closable neck end for a filler neck of a tank of a motor vehicle, the cap-free closeable neck including an upper entry space forming an insertion region for a fuel nozzle and being surrounded by a side wall, a lower sealing flap arranged in the upper entry space and closing mechanism arranged above the lower sealing flap. The closing mechanism includes an upper filling opening and an upper cover, which in a closed state at least partially covers the upper filling opening and being embodied in such a manner that the upper cover is displaced by inserting an outlet pipe of a fuel nozzle into the upper entry space for releasing the upper filling opening so as to allow for the insertion of the outlet pipe through the upper filing opening and the lower sealing flap.

Abstract: A cap-free closable neck end for a filler neck of a tank of a motor vehicle may include an upper entry space forming an insertion region for a fuel nozzle and being surrounded by a side wall, a lower sealing flap arranged in the upper entry space and closing mechanism arranged above the lower sealing flap, which includes an upper filling opening and an upper cover, which in a closed state at least partially covers the upper filling opening, and such that the upper cover is displaced by inserting an outlet pipe of a fuel nozzle into the upper entry space for releasing the upper filling opening to allow for the insertion of the outlet pipe through the upper filing opening and the lower sealing flap.

Abstract: The invention relates to a capless filler neck having an upper closure flap 2 and a lower closure flap 3, which are arranged in a pipe section 1. The two closure flaps 2, 3 must be able to seal independently of one another. In known capless filler necks, this has the effect that, when the filler pipe 4 of a fuel nozzle is still partially inserted, the lower closure flap 3 is already closed, whereas the user still has the impression that tank filling can be carried out. As a result, fuel collects between the two closure flaps 2, 3. The invention prevents this in that the lower closure flap 3 is opened or held open by the upper closure flap 2 or by an actuating element even when the filler pipe 4 is no longer in contact with the lower closure flap 2.

Abstract: The invention relates to an in particular capless neck end for a container, in particular a fuel container, with a double-flap closure which is formed by an upper pivoting flap (12) and a lower sealing flap (2). Neck ends of this type are known from WO 2006/084908. These known neck ends require too much installation space and are not optimally protected from the contents of the container being pumped out. This is improved by the invention in that the lower sealing flap is arranged in such a manner that it is arranged at an angle to the transverse section plane arranged at right angles to the neck axis (S) when in the closed state, and either the articulation point or, when in the closed state, the end opposite the articulation point of the lower sealing flap is arranged above the lower end of the first circular segment path. Furthermore, an anti-theft means (25) in the form of a mechanical barrier is provided below the double-flap closure.

Abstract: A tank cap with free travel to close a fuel tank of a motor vehicle can be screwed on a filler neck of the fuel tank so that it seals via rotational movement around a rotational axis and features a closure body having a transverse support and a cap body having a transverse support. One of the supports includes a contact surface and a raised outer area that serves as a limit stop. The cap body is pivoted for rotational movement relative to the closure body through a free travel angle ? that is limited by the limit stop.

Abstract: The invention relates to a tank cap for closure of a fuel tank, which can be screwed onto a filler neck and has an inner closure element as well as a cap element and is mounted so as to rotate against the force of a return spring around an angle of free travel that is limited by a first stop and a second stop. The return spring is arranged between the closure element and the cap element so that the longitudinal axis of the return spring lies in a plane that is perpendicular to the axis of rotation of the tank cap.
