The invention relates to a pump module () comprising a housing part () with precisely determined force introduction points () in relation to adjacent components. Supporting elements () and a groove () are located between the force introduction points () and a disc element () that comprises a partially annular channel (). Forces that are introduced into the housing parts () thus lead to negligible deformations in the areas of said housing parts () that are adjacent to the impeller.

Fuel pump

A fuel pump unit comprising a housing part () arranged between an electric motor () and a fuel pump (). The housing part is provided with expansion joints for compensating thermal expansions or swelling of the material of the housing part (). The gap between the impeller () and the housing parts () of the fuel pump () can be kept constant by virture of the expansion joints, whereby the fuel pump () is essentially prevented from jamming especially when it runs dry.

Fuel feed unit

The invention relates to a supply pump embodied as a side channel pump, whereby several sections (-) forming the cross-section of a supply chamber () each comprise radii. The origins of the external radii are arranged on the front face of a pump housing facing the one rotor. The sections (-) comprise common tangents in the adjacent regions thereof. A particularly high efficiency for the supply pump can thus be guaranteed.

Supply pump

In a fuel pump () designed as a side channel pump, in each case two conveying chambers (-) one surrounding the other concentrically are arranged on two impellers (). The conveying chambers () of one impeller () are connected to an inlet duct (), while the conveying chambers () of the other impeller () are connected to an outlet duct (). A connection () of the conveying chambers (-) is arranged in a partition () keeping the impellers () at a distance from one another. As a result, the fuel pump () has an especially high volume flow, along with a very high conveying pressure.

Fuel pump for a fuel tank

The invention relates to a pump unit arranged in an inner tank () of a fuel tank, comprising a fuel pump () which is used to pump fuel to the internal combustion engine of a motor vehicle; an ejector pump () which is connected to the fuel pump () and used to pump fuel out of the fuel tank into the inner tank (); and at least one filter element () which is used to filter fuel, wherein a housing part which is connected to the fuel pump () is provided with at least one channel () for guiding said fuel. In order to simplify the structure of the pump unit () and to enable substantial pre-assembly, the housing part () is configured in such a way that it can hold the at least one filter element (), and the channel () is exclusively guided inside the housing part () from the ejector pump () and/or the fuel pump () to the filter element ().

The invention relates to a filter module () for a fuel conveying unit () comprising a fuel pump () with two pump chambers () which are independent of each other. A common filter area () is provided for the inlet areas () of the pump chambers (). The filter module () has a connector () which can be inserted into a recess of a housing part (). The configuration of the filter module () is particularly economical as a result.
