Embodiment Construction

[0015] figure 1 A fuel tank 1 of a motor vehicle (not shown further) is shown, which has a delivery unit 2 which is inserted through an opening 3 in the fuel tank 1 . After assembly, the opening 3 is closed with the flange 4 . The delivery unit 2 comprises a swirl pot 5 which is prestressed with respect to the bottom of the fuel tank 1 . Arranged in the swirl pot 5 is a fuel pump 6 which sucks the fuel out of the swirl pot 5 and conveys it through the discharge sleeve 7 . In addition, a fuel filter 8 is also arranged in the anti-swirl tank 5, which is arranged downstream of the fuel pump 6 from the flow direction, so that the fuel delivered by the fuel pump 6 passes through the input sleeve 9 to reach the fuel filter. device 8. The filtered fuel then flows via a feed line 10 via flange 4 to a motor vehicle internal combustion engine (not shown). The housing 11 of the fuel filter 8 has a one-piece injection-molded web 12 which is integrated into a pump holder 13 . In the p...

Abstract

The invention relates to a pump unit for pumping fuel from a fuel reservoir to an internal combustion engine of a motor vehicle, comprising a fuel pump, which is disposed in a swirl pot and has a housing made of metal, and a fuel filter, which is disposed downstream of the fuel pump. The housing of the fuel filter is connected to the housing of the fuel pump in an electrically conductive manner.

Description

technical field [0001] The invention relates to a delivery unit for delivering fuel from a fuel tank to an internal combustion engine of a motor vehicle, the delivery unit having a fuel pump which is arranged in a swirl pot and has a housing made of metal, The delivery unit also has a fuel filter which is arranged downstream of the fuel pump. Background technique [0002] Delivery units of this type have been known for a long time and are therefore prior art. It is also known to provide a fuel filter for the swirl pot. According to the prescribed safety rules, components that come into contact with flowing liquids must be protected against electrostatic charges. This increases the outlay for producing the delivery unit. Contents of the invention [0003] It is therefore the object of the invention to provide a delivery unit which is inexpensive to produce. [0004] According to the invention, this object is achieved in that the housing of the fuel filter is electricall...
