A filling level indicator for determining a filling level in a tank, having a resistor network arranged on a carrier substrate, a contact element, and a magnetic element. The contact element is arranged adjacent to the resistor network and the magnetic element is movable relative to the resistor network and the contact element. The contact element has a contact region deflectable by the magnetic element. An electrically conductive connection between the contact region and the resistor network is produced by the deflection of the contact region. The contact element has an attachment region connected to the carrier substrate, and the contact region is formed spaced apart from the resistor network and the carrier substrate.

A method for the production of a suction jet pump delivering fuel into or out of a fuel tank, wherein the suction jet pump has a flow channel and a nozzle, and wherein the flow channel forms a feed line to the nozzle and the flow channel is formed in one piece with the nozzle, the method including, in the following order: placing a mold core into a matrix to produce the suction jet pump by injection molding and form a cavity between the mold core and the matrix; encapsulating the mold core and filling the cavity formed between mold core and matrix with a plastic; removing the mold core through an installation opening, arranged opposite the nozzle, in the flow channel; and closing the installation opening by thermal deformation, in the edge region of the installation opening, of the plastic used for the production of the suction jet pump.

A filling level indicator includes a retainer, a bow rotatably supported on the retainer and having a lever arm fastened thereto, a float fastened to the lever arm, and a filling level sensor arranged in the retainer. The filling level sensor has a substrate, a resistance network arranged thereon, a contact spring structure, and a cover, connected to the substrate, that covers the resistance network and the contact spring structure. A magnet is connected to the bow or the lever arm and acts on the contact spring structure such that an electrical signal corresponding to the filling level is generated according to the pivoting range. The mount has a wall thickness that can be penetrated by the magnetic field of the magnet, and so metal particles are held on the outside of the mount by the magnetic field of the magnet.

A device for contacting at least one conducting track has a contact spring that is connected to a pivotable bow by a pivot bearing. The contact spring also has spring elements connected in series for preloading contacts against the conducting track. An axis of the pivot bearing is arranged parallel to the direction of motion of the contacts over the conducting tracks.

A level indicator having a support, a thick-film resistor network arranged on the support, a bow that carries a contact structure that produces, depending on the position of the bow, an electrical signal in the thick-film resistor network, a lever arm that is retained in the bow and has a float on its other end. The float has a seat for the lever arm. The lever arm has a pivoting range in a first plane. The float has a second plane that is perpendicular and that extends perpendicular to the first plane and through the center of mass of the float. The float is mounted on the lever arm to be positionally immobile. The seat for the lever arm is arranged in a region of the float which is arranged on the side of the second plane that faces away from the seat of the bow and that is delimited by the second plane and the outer periphery of the float.

A signal transmitter for a filling level sensor has two sliding contacts which are manufactured integrally with a holder and with spring elements. This leads to the manufacturing costs of the signal transmitter being particularly low. The sliding contacts are arranged on spring tongues and are connected to one another via a link. The spring tongues and the spring elements are therefore arranged in a row and allow the sliding contacts to be prestressed particularly uniformly against sliding tracks of the signal transmitter.

A magnetic passive position sensor including a base plate and a cover which form a housing, a magnet that can be moved outside the housing, a resistance network that has several individual electric contacts, and a plurality of contact spring elements that are arranged within the range of motion of the magnet, are interconnected by a common base, and consist of a bending zone and a contact zone. The contact spring elements face the contacts of the resistance network in such a way that the contact zones can be moved from the magnets against the contacts of the resistance network, the contact zones of at least two contact spring elements being assigned to each individual contact of the resistance network. Two adjoining contact spring elements are mechanically interconnected.

Filling level sensor

A filling level sensor having a lever arm which has a float at one end and is held at its other end by a clip. A resistance network is arranged on a substrate and to which a contact structure is assigned, the resistance network producing an electrical signal for the filling level as a function of the pivoted position of a lever arm. The clip is composed of an electrically conductive plastic and has an electrical contact connected to the clip in an electrically conductive way, such that as the lever arm pivots said contact describes a circular path on the substrate.
