摘要： A motor driven fuel pump adapted for use with a fuel injection system of an internal combustion engine has a pump housing and an impeller of regenerative pump type rotatably disposed in the housing and provided with circumferential rows of grooves formed in the opposite end faces of the impeller along the outer peripheral edges thereof. The housing is formed therein with suction and discharge ports and cooperates with the impeller to define a fuel pressurizing passage extending circumferentially of the impeller and surrounding the grooved outer peripheral section thereof. The fuel pressurizing passage is circumferentially interrupted by a partition wall disposed between the suction and discharge ports and extending radially inwardly into close contacting relationship to the outer peripheral section of the impeller to prevent flow of fuel from the discharge port toward the suction port. The discharge port is tangential to the fuel pressurizing passage to facilitate smooth flow of the pressurized fuel from the passage into the discharge port and reduce the amount of material required for the pump housing.

摘要： 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.

摘要： In a fuel pump driving apparatus for a vehicle engine including a fuel injection system, the selection of a plurality of energizing circuits each formed by the combination of two or all of three brushes of a fuel pump drive motor is effected in accordance with the load conditions of the engine, thereby changing the rotational speed of the motor and hence the fuel quantity delivered from the fuel pump. When the occurrence of a fault in one of the energizing circuits is detected, the driver is informed of the occurrence of the fault and in addition a faulty-condition controller controls switching means in such a manner that the drive motor is energized through another one of the energizing circuits.
