A device for measuring the level of a fluid in a container by means of a sound guide tube and an ultrasonic transducer disposed inside the container mounted in a fluid feeding device within the container.

Device for measuring the level of a fluid in a fuel tank of a motor vehicle

A method and a device are described for diagnosing a fuel system having a plurality of electric fuel delivery units, which are submerged on the inlet side in a fuel supply contained in a fuel tank, and which, on the outlet side, deliver fuel in a fuel line to an internal combustion engine. The currents of the electric fuel delivery units are measured directly or indirectly in an analysis unit, compared to one another, and a diagnostic signal in digitized form is generated as a function of the result of the comparison.

Method and device for diagnosing the failure of a fuel delivery device in a fuel system

A feeding aggregate for fuel has a feed pump which is formed as a side channel pump and has a housing, a pump chamber formed in the housing, and an impeller arranged in the pump chamber, an electric motor provided for driving of the impeller and having a stator and a rotor, with the rotor formed of one piece with the impeller, the feed pump having at least one pump stage, a rim of vanes having vane chambers therebetween and provided on at least one end side of the impeller, a partial ring-shaped side passage formed in the housing opposite to the rim of vanes and having an inlet and an outlet spaced from one another in a peripheral direction of the impeller and open into the side passage, the at least one pump stage of the feed pump having the rim of vanes only on one end side of the impeller and having the side passage in the housing opposite to the rim of vanes, the inlet and the outlet of the side passage being arranged at a same end side of the impeller, and the impeller at an end side which is opposite to the vanes being provided with recesses which are at least approximately mirror-symmetrical to the vane chambers and are connected through openings in the impeller with the vane chambers.

A unit for delivering fuel from a supply tank to an internal combustion engine, having a disklike impeller driven to revolve in a pump chamber, on whose circumference a number of blades are disposed, and having at least one supply conduit, disposed in the region of the impeller blades and open toward the impeller, in a chamber wall defining the pump chamber on the face end and axially adjoining the impeller, which supply conduit extends via a split ring around the pivot axis of the impeller from an inlet opening into the pump chamber to an outlet opening from it. In order to assure that sufficient fuel can be aspirated unthrottled in the presence of gas bubbles in the fuel, in particular when the fuel is hot, the supply conduit is embodied in the region of the inlet opening as larger by a factor of 2 than the usual supply conduit cross section; the cross section of the supply conduit then decreases continuously, beginning at the inlet end, forming a compression conduit.

An impeller wheel for feeding a medium, for example fuel, includes a plurality of vanes spaced from each other at non-uniform intervals along the periphery of the impeller wheel. To reduce tonal noise to a minimum during the feeding of the medium the vanes are distributed in accordance with the mathematical interrelations of a pseudonoise sequence.
