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).

摘要： Disclosed is a fuel pump which is embodied as a side channel pump and is used for conveying fuel into a fuel reservoir of a motor vehicle, and in which a partially annular duct (13) that extends to a discharge duct (8) is configured in a continually expanding manner. A partially annular duct (12) that is connected to an intake duct (7) tapers in the direction of flow. Blade chambers (10) that are disposed within an impeller (6) form a conveying chamber (14) along with the partially annular ducts (12, 13). Said conveying chamber (14) extends from the intake duct (7) to the discharge duct (8) and is provided with a constant cross section such that the impeller (6) is continuously penetrated by a flow.
