A pump apparatus has a rotor shaft, a pump impeller connected to the rotor shaft, at least one axial bearing which rotatably supports the rotor shaft at a side facing the pump impeller, a magnetic pump stator, a magnetic pump rotor which is connected to the rotor shaft, a containment can which extends between the stator and the rotor, and at least one central support element which is mounted in the region of the pump impeller. The pump apparatus has an elastomer disk which is arranged between the support element and the axial bearing. The stator and the rotor are arranged with an axial offset with respect to each other. The stator and the rotor are provided as a result of the axial offset to produce an axial force F in the direction of the elastomer disk.

In known devices for pumping fuel, suction jet pumps are used which are driven by the fuel flowing back from the internal combustion engine and pump fuel from a supply tank into an impoundment container of a fuel pumping unit. In known suction jet pumps, the suction power is limited by the fact that the fuel stream applies itself to the housing wall, so that the entire area of the fuel stream is no longer available for entraining fuel. The device of the invention lessens this effect by providing at least one rib between the first partial section of the fuel line and the mixing conduit.

The invention proposes a transverse flux machine, in particular a unipolar transverse flux machine, with at least one stator module contained in a housing composed of two axially joined housing parts and having an annular coil disposed concentric to the housing axis as well as stator elements that embrace this annular coil from the outside and inside. For ease of assembly of the individual parts and for a precisely toleranced maintenance of a small air gap between the stator and the rotor, clamps that protrude axially from the respective housing parts oriented toward each other are provided for the stator elements and have positioning elements for securing them in the radial direction.
