Pump unit arranged in an inner tank of a fuel tank of a motor vehicle

摘要

The invention relates to a pump unit arranged in an inner tank ( 3 ) of a fuel tank, comprising a fuel pump ( 5 ) which is used to pump fuel to the internal combustion engine of a motor vehicle; an ejector pump ( 21 ) which is connected to the fuel pump ( 5 ) and used to pump fuel out of the fuel tank into the inner tank ( 3 ); and at least one filter element ( 20:31 ) which is used to filter fuel, wherein a housing part which is connected to the fuel pump ( 5 ) is provided with at least one channel ( 30;33;35;47 ) for guiding said fuel. In order to simplify the structure of the pump unit ( 2 ) and to enable substantial pre-assembly, the housing part ( 24;40 ) is configured in such a way that it can hold the at least one filter element ( 20;31 ), and the channel ( 30;33;35;47 ) is exclusively guided inside the housing part ( 24; 40 ) from the ejector pump ( 21 ) and/or the fuel pump ( 5 ) to the filter element ( 20;31 ).
