Abstract
A motor pump comprises a DC motor unit, a pump unit and a cover housing for the motor and pump unit; the motor unit includes a cup-shaped yoke with the bottom having a bearing, and a bearing holder is fitted into an opening in the cup-shaped yoke to thereby hold an armature shaft of the motor unit in position with respect to the yoke. The pump unit has a pump stator secured to the bottom of said cup-shaped yoke and a pump rotor connected to the armature shaft by key arrangement. The pump stator has a passage communicating the gap in the key arrangement and the pump inlet. As a result, fuel in the gap is prevented from stagnating therein, thereby preventing rusting of the pump components.
