Automotive fuel pump

An automotive fuel pump has a tubular shell (12), a pump group (14) in the shell (12), an end housing (16) in the shell (12), and an electric motor (18) in the shell (12) including an armature shaft (52). The armature shaft (52) has an integral annular first spherical shoulder (78) engaging a seat (86) of a first bearing (84) on a partition wall (20c) of the pump group (14). The first bearing (84) reacts against axial thrust and radial bearing forces between the partition wall (20c) and the armature shaft (52) and supports the armature shaft (52) on the partition wall (20c) for rotation about the centreline (82) of the shaft (52) and for universal pivotal movement about the centre of the first spherical shoulder (78). The armature shaft (52) has an integral second spherical shoulder (94) received in a cylindrical bearing seat (92) of a second bearing (90) on the end housing. The second bearing (90) reacts only against radial bearing forces between the armature shaft (52) and the end housing (16) in a plane perpendicular to the centreline (82) of the bearing seat (92), whereby the armature shaft (52) is supported on the end housing (16) for rotation about the centreline (82) of the armature shaft (52) regardless of whether the centreline (82) of the armature shaft (52) coincides with the centreline of the cylindrical bearing seat (92).
