Abstract: A tank closure comprises first and second closure members which, as a result of the insertion of a fueling nozzle, are movable between a closed position and an open position. A bypass has a venting valve that is connected to the first closure member so that upon motion of the first closure member out of its closed position toward an open position, the venting valve is likewise moved out of a closed position into an open position, and vice versa. A stop device comprises a movable stop element operationally connected to the first closure member and/or to the venting valve. Opening of the second closure member causes the stop element to travel into the motion region of the second closure member. With the closing motion of the first closure member, the stop element travels back into the initial position.

Abstract: A tank closure comprises a tank cap and an electrically conductive tank neck. The tank cap has, for handling thereof, a grip portion made of electrically conductive material that is in electrical contact with at least one resilient contact projection that is also electrically conductive and, with the tank cap in the screwed-on state, rests against the tank neck. The contact projection or projections is or are shaped onto or molded into the grip portion.

Abstract: A closure stopper having a seal for a filler neck has first locking faces and a first sealing face, and the closure stopper has second locking faces and a second sealing face. The functions of the sealing ring and of the locking device are not impaired by the effects of temperature because (a) the smallest radius of the first sealing face is larger than the largest radius of the second sealing face, and (b) the sealing ring is a resilient circular ring with a first and a second sealing surface, of which, when the closure stopper is inserted, one surface bears against the first sealing face and the other face bears against the second sealing face. The sealing ring has a core made of resilient steel.

Abstract: A fuel cap and filler neck fitment for receiving the fuel cap. The fuel cap includes an outer member and an inner closure assembly with seal. The cap and fitment both include lugs which interengage when the cap is moved into a closing position to pressurize the seal determined by an improved overriding ratchet arrangement. During removal of the cap, the outer member moves against a spring action for a predetermined arc before the inner closure assembly is moved to disengage the seal. When the seal is disengaged, the spring action takes up the relative motion. Once removed, the cap is retained by an improved tether assembly. The outer member is connected to the inner annular assembly by an improved structural arrangement which allows the outer member to separate under crash impact.

Abstract: A nipple is attachable to the outer end of the fill pipe of a motor fuel tank and contains a closure flap and a number of other valves performing various functions. The nipple therefore can have unified in it mechanisms performing most or all of the functions required in association with the tank and can be made as a pre-assembled unit quickly and easily attached to a fuel tank in the manufacture of a vehicle to minimize the number of required assembly procedures.

Abstract: In a closure cap for a container, especially for a vehicle radiator, with an outer part (12), an inner part (16) of cup-shape connected with the outer part and insertable into the opening to be closed, and having an overpressure valve arranged in the inner part for opening and closing a pressure compensation channel running through the inner part (16), which overpressure valve includes an axially movable first valve body (26) which carries a first ring shape substantially radially extending sealing surface (36) biased against a ring-shaped first countersealing surface (48) by a spring urging the first valve body toward the bottom of the inner part (16), the first outwardly directed countersurface (48) is formed by a second valve body (46) movable axially between two end positions, which second valve body has an opening radially inside of the first countersealing surface (48) and radially outside of the first countersealing surface has an inwardly facing second ring-shaped sealing surface (52) and an outwardly

Abstract: A cap for the pipe of an automobile radiator or the like includes a pressure/vacuum valve. The pressure at which the valve opens may be adjusted by an easily operated means permitting adjustment of the compression of a pressure spring, thereby making it possible to reduce the effect of spring tolerances on opening pressure tolerances.

Abstract: A sealing cap has an external cover section of external diameter greater than a circular sealing face about an opening. An internal cover projects into the opening, and a tightener is provided. A diametral handle is molded on the external cover section and has a U-shaped stirrup with two legs connecting it to the external cover section, and a wall extending along the center of the stirrup and connecting it to the external cover section. The improvement of the invention is that each cover section is made as a one-piece molding, and the legs of the stirrup are spaced by not less than the external diameter of the cover section sealing face, and the length of the wall, longitudinally of the stirrup, is less than the internal diameter of the cover sealing face.
