A capless fuel door assembly including a body pivotally supported within a housing of the vehicle between closed and opened positions. The body includes an exterior projection exhibiting an angled slide. A spring is secured to the housing and includes an extended portion supported against an end stop location of the projection defining a first end of said angled slide in order to exert the body in the closed position, with opening of the body about the pivot causing a decrease in the closing force as the spring portion displaces along said angled slide to a second end to achieve the opened position.

A capless closure device including a body, an end plate provided with a circular opening adapted for receiving a fuel nozzle, and a flap door adapted to close the circular opening, where the capless closure device includes a latch edge arranged at the lower edge of the circular opening and a spaced apart sealing edge, and where an inlet drain opening is arranged between the latch edge and the sealing edge. The advantage of the invention is that a capless closure device with an integrated drain passage is provided in a cost-effective way.

The fuel tank cap with charcoal canister includes a fuel tank inner cap and a fuel tank outer cap. A filling chamber is disposed in the fuel tank inner cap. The fuel tank outer cap wraps up the upper port of the filling chamber. The fuel tank inner cap has a volume chamber having an upper vent cap. Between the side wall of the upper vent cap and the inner wall of the volume chamber, there is an air gap. The filling chamber has a lower breathing panel. Between the lower breathing panel and the bottom of the filling chamber, there is a welding ring. The upper port is on the inner side of the welding ring. The lower surface of the lower breathing panel is fixed and connected with the filling chamber via the welding ring. The bottom surface of the volume chamber has an air inlet/outlet.

A closure device for a fluid container, in particular a hydraulic tank, having a base (4), which can be attached to the container opening thereof, and a cover part (2), which encloses a ventilation and/or a filter device (36), is held on the base (4) so as to be freely rotatable in a functional unlocking position and, in a further functional locking position, permits the container opening to be unlocked by means of a safety device (48, 50, 58) while connecting the cover part (2) to the base (4), is characterized in that the safety device (48, 50, 58) can be actuated by a device generating a magnetic field (62), which device establishes the further locked functional position of the cover (2) and the base (4) by means of magnetic force.

A closure of a tank of a motor vehicle for closing a filler neck gas- and fluid-tight, having a closure fastened to a flap, the flap being fastened to a vehicle body of the motor vehicle such that it is movable into an open or closed position, the closure including a seal, which causes the closure to close against the filler neck. The tank closure should be easy for a user to handle and have a relatively simple design and be economical to manufacture. This is achieved in that the seal is electromechanically or pneumatically adjustable with the aid of an actuator.

The present invention relates to a tank cap including a lever member that is constrained from moving to the standing position contrary to the intention of the operator. The tank cap comprises a slide member disposed in the cap body so as to be adjacent to the lever member, and provided with a cam contact portion that is to come into contact with a cam portion of the lever member, and a coil spring disposed between the slide member and the bottom of the cap body. The resilience of the coil spring causes the cam contact portion to press the cam portion and retains the retracted position.

A closure system including a filler neck, a guide socket arranged inside the filler neck, a closure cap to be introduced between the filler neck and the guide socket and which is fastenable to the filler neck and an annular seal to be received in an annular groove of the closure cap and which is secured to an inner face of the filler neck. The annular seal is arranged between the filler neck and the guide socket such that a nozzle placed between the filler neck and the guide socket does not reach thereto.

A closure of a tank of a motor vehicle for closing a filler neck gas- and fluid-tight, having a closure fastened to a flap, the flap being fastened to a vehicle body of the motor vehicle such that it is movable into an open or closed position, the closure including a seal, which causes the closure to close against the filler neck. The tank closure should be easy for a user to handle and have a relatively simple design and be economical to manufacture. This is achieved in that the seal is electromechanically or pneumatically adjustable with the aid of an actuator.

The invention relates to a tank cover for mounting on a filler neck of a container, including a grip cap, a threaded part and a locking mechanism which is provided between the grip cap and threaded part, wherein the locking mechanism is formed by latching noses and by elastically deformable latching lugs interacting therewith, the latching lugs are integrally formed on the threaded part and the latching noses are integrally formed on the grip cap, or the latching lugs are integrally formed on the grip cap and the latching noses are integrally formed on the threaded part. Here, the latching lugs are formed on or in the vicinity of a thread turn of the threaded part.
