Abstract: In a lever transmitter for a fuel tank, two spring tongues, each with a sliding contact, are arranged on a contact plate of a potentiometer. The contact plate is prestressed against sliding tracks of the potentiometer by a spring element fastened to the carrier and having the sliding contacts due to vibrations are thereby reliably avoided.

Abstract: A delivery device (2) for delivering fuel, having a delivery pump (3) and a fuel filter (7), has a bypass line (9) which is conducted past the fuel filter (7). When new, the delivery pump (3) delivers fuel through the fuel filter (7). After the fuel filter (7) has become clogged with dirt, the fuel is delivered by the bypass line (9) through a second fuel filter (10). By this means, pollution of the environment with fuel is kept particularly low.

Abstract: A feed device (2) for fuel in a motor vehicle has a pressure regulating valve (7) arranged in a forward-flow line (6) leading to an internal combustion engine. The pressure regulating valve (7) is activated by a pressure within a return-flow line (10) and opens or closes a branch (8) leading to a suction jet pump (5). A pressure provided in the forward-flow line (6) can thereby be regulated with particularly high accuracy.

Abstract: A pump assembly is comprised of a pump member having a pump wall and a filter element located within a filter housing that is prestressed against the pump wall. In an exemplary embodiment, a housing of the pump assembly is manufactured in a single piece with a clamping element. The clamping element includes a flanged border for gripping behind an edge of the filter housing.

Abstract: Stranded cable conductors, especially their connecting joints with electrical components, are damaged during use in aggressive surroundings, for example in fuels. Protective measures, such as shrinkable tubes or protective coatings, do not ensure adequate protection however. With the novel process, stranded cable conductors and their connecting joints with electrical components are to be protected against the attack of aggressive media. With the process according to the invention, stranded cable conductors are encapsulated in a fuel-resistant plastic, the encapsulation not covering the entire length of the stranded cable conductor but the region which is exposed to aggressive media. The process does not require any pretreatment of the stranded cable conductors.

Abstract: A fluid level sensor that is particularly useful in fluid fuel tanks of motor vehicles wherein a resistor network is arranged on a fixed support and it is possible to generate an output signal from the resistor network which corresponds to the position of a float member. The level sensor has particularly low wear and is inexpensive to produce with a contact structure for the resistor network that operates through interaction of a magnetic member is moved by the float and can be deflected such that an electrical connection is dependent on the position of the float.

Abstract: In the case of a fuel tank for a motor vehicle, a filling pipe (2), which is welded to a tank chamber (1), has a section (3) provided for the separation. The section (3) provided for the separation is adjoined by regions for the attachment of a connecting part. This enables the tank chamber (1) to be taken out of the motor vehicle and to be subsequently refitted without removing the entire filling pipe (2).

Abstract: According to the invention, in the case of a multifunctional valve for a vehicle container, comprising a first opening which can be closed by means of a first closing body as a function of the filling level of the container and is intended for ventilating the tank as it is being filled, a second opening which can be closed by means of a second closing body and is intended for ventilating the tank during operation, the two closing bodies automatically going into their closing position if the vehicle takes up an excess sloping position or undergoes a roll-over action, the two closing bodies (13, 18) can be brought into the closing position by a respectively assigned first or second float body (11, 17) which are of lower density than the medium in the container, and in the event of a roll-over action, a mechanical device (ball 19) acts upon the two float bodies (11, 17) to counter their buoyancy and keep the closing bodies (13, 18) in the closing position.

Abstract: A fuel tank (1) possesses, for the introduction of fuel, a filler pipe (5) which is led through an orifice (6) of the fuel tank (1) with all-round clearance. The orifice (6) is sealingly closed by means of a sleeve (4) bearing against the fuel tank (1) and against the filler pipe (5). The orifice (6) can thereby be made relatively large, so that it can be additionally used also as a service or assembly orifice after the sleeve (4) has been removed. The number of orifices necessary on the fuel tank (1) can be reduced as a result, so that both the maximum filling quantity and the permeation tightness can be increased.

Abstract: A fuel tank (1) has an ejector pump (9) arranged inside it. This ejector pump (9) is preloaded against an inner wall (10) of the fuel tank (1) by means of a flexurally elastic supporting arm (8) and is thus fixed. This allows the ejector pump (9) to be inserted into the interior of the fuel tank (1) without problems through an opening (3) together with a fuel feed unit (4). This considerably simplifies the fitting of the ejector pump (9) and, in particular, there is no need for another fitting opening in the fuel tank (1) to enable the ejector pump (9) to be fixed.

Abstract: A feed pump (2) designed for feeding fuel in a motor vehicle, with an impeller (7) having vane chambers (10, 10a, 11, 11a) delimited by guide vanes (12, 13), and in casing parts (3, 4) adjacent to the impeller (7) and having part-annular channels (14, 15) arranged in the region of the vane chambers (10, 10a, 11, 11a), has a degassing duct (19), the start of which is arranged downstream of an inlet port (8). Some of the vane chambers (10) are connected to the degassing duct (19) via pockets (20) worked into the impeller (7). By means of this degassing duct (19), gas bubbles present in the fuel are discharged reliably from the feed pump (2).

Abstract: A suction jet nozzle and a diffuser having an inflow cone with an elliptical cross-section is implemented in a suction jet pump to be used in a motor vehicle's fuel tank. The jet nozzle is configured to produce a flat propulsion jet that seals the diffuser over its entire circumference.

Abstract: A gas-pedal module has a gas pedal (12) which is mounted pivotably in a housing and can be actuated, counter to a restoring spring, with pedal-force-dependent hysteresis, a pedal-position sensor producing an electric signal corresponding to the pedal position. In view of the high pedal forces, precise and expensive bearings are necessary in order to avoid jamming of the gas pedal (12). In order to reduce the production costs arid nevertheless reliably to prevent jamming, it is proposed to mount the gas pedal (12) in a floating manner in a bearing element (28) which has play in the upward direction. Specific selection of the coefficient of friction on the contact surface (30) between the bearing journal (18) and the bearing element (28) makes it possible to achieve a hysteresis as is desired in the case of such gas-pedal modules.

Abstract: In a pressure-regulating arrangement between a pump and a load, in particular between a fuel pump and an internal combustion engine, in which, if the flow from the pump exceeds a predetermined pressure, a cutoff quantity is branched off and fed back into a storage container, according to the invention the pressure regulator (9), together with the cutoff line (14), is combined with a filter (2) in one structural unit. All three connections (feed (4), flow (7) and cutoff connection (15)) are preferably arranged on the same side of a common housing (1). In a particularly advantageous embodiment, all three connections are arranged coaxially with one another, so that if an appropriate connecting piece is used, installation faults can be ruled out.

Abstract: A filling level sensor has a carrier part (1) having a lever wire (3) which is attached to a bracket (2) and is axially guided by a bar-shaped apron (11). The bracket (2) has webs (9, 10) which protrude radially with respect to its pivotable and axially nondisplaceable bearing and over which flange elements (7, 8) of the carrier part (1) engage. As a result, the bracket (2) is at a constant distance from the carrier part (1) and is additionally of particularly simple design.
