The automatic tank closure is integrated in an insert. The filling-fixture forms a recess on its upper end into which the insert can be placed. A fissure joint is sealed with the aid of a sealing element between the filling-fixture and the insert and the securement of the insert in its recess is assured by a retaining flange. The flange is circumferentially connected in a radially outlying area with the filling-fixture and the flange extends so far radially inward that it covers the fissure joint and an inward extending area of the upper side of the insert.

Abstract: The invention concerns a filling fitting for a fuel tank of a motor vehicle having an automatic tank closure. The filling fitting includes a carrier with an inlet opening and a closure cover, which closes the inlet opening with a sealing element. An upper side of the closure cover has a closure component, which, in a closed position of the closure cover, penetrates the inlet opening. Above the carrier is a circumferential section placed directly or indirectly on a supporting closure ring. The section extends inward to coact with closure elements on the closure component in the manner of a screw drive. To prevent permeation, in a force transmission path between the sealing element of the closure cover and the carrier, at least one axial, effective spring element is inserted.

In addition, three shape memory alloy actuators are provided between the structures and symmetrically arranged about the compliant support. The shape memory alloy actuators are selectively activated to provide two degrees of freedom of movement for the moveable structure relative to the support structure.

Abstract: A thick-film resistance 9 with a conductive path 8 of electrically conductive material is provided in the case of a fuel level transmitter for a fuel tank of a motor vehicle. The conductive path 8 is contacted in a sliding manner by a contact element. The material of the contact element exhibits a silver content, which has been reduced in such a manner, that an increase in the resistance of the contact ascribable to the formation of silver compounds, especially silver sulfide, silver sulfite and silver sulfate on the contacting surfaces is negligible.

Abstract: In one embodiment of the present invention, a shape memory alloy (“SMA”)-actuated flow controller comprises a number of grille members, each having a long axis and being slideable relative to one another parallel to that long axis. The SMA-actuated flow controller also includes a frame configured to guide the number of grille members, and an actuator disposed within the frame to move at least one of the number of grille members for varying a size of an aperture. Further, the actuator includes an SMA actuator that includes a number of SMA elements each connecting one grille number to another.

Abstract: An actuated gauge pointer that includes a shape memory alloy element configured to move the gauge pointer when activated is provided. The actuated gauge pointer includes a first shape memory alloy element disposed within the perimeter of the gauge pointer housing. Additionally, the actuated gauge pointer may include a second shape memory alloy element to provide temperature compensation, and a bias member to return the gauge pointer to an initial condition.

Abstract: The invention concerns a level limit valve for the fuel tank of a vehicle. Such valves serve the purpose, that upon the filling of the fuel tank, the filled quantity of the fuel is limited. The proposed level limit valve possesses a valve body 1 which can be positioned within the fuel tank at the end of a filling pipe. The valve body is equipped with an intake port 22 which is connectable with the said filling pipe and an outlet port 21 emptying into the interior of the fuel tank. Further, in the valve body 1 is found a flap 4, which is pivotally movable between a position tightly sealing the outlet port 21 and a position wherein this is opened. The float 3 is movably connected to said flap 4 by means of a lever rod 5. The lever rod 5 penetrates the outlet port 21 at least in the opened position of the flap 4 and is connected by means of linkage with that outer side 28 of the flap 4 which is proximal to the outlet port 21.
