Abstract (en)

[origin: WO9200449A1] The proposal is for an assembly for feeding fuel from the fuel tank (10) to the internal combustion engine (18) of a motor vehicle. The feed assembly (12) comprises a feed pump arranged in the fuel tank and taking the form of a full-flow pump whose substantially cylindrical rotary impeller (34) is arranged in a correspondingly cylindrical pump chamber (36) and where at least one approximately annular feed channel (50) grooved in cross-section extends in at least one of the two chamber front walls from a suction aperture (58) opening into the pump chamber to a pressure aperture (68) leading therefrom and this chamber front wall is pierced in the region of the pressure aperture by a drilling (70) connecting the pump chamber with a region of the system in which underpressure prevails. Particularly reliable removal of gas bubbles from the pump and hence from the feed path is obtained in a simple manner in that this drilling is in a sealing surface (64) radially limiting the feed channel in relation to the axis of rotation of the impeller.
