    • An electric fuel pump for an internal combustion engine in which a pump mechanism is provided in a housing for pumping fuel from an inlet to an outlet of the housing. A d.c. motor in the housing is drivingly connected to the pump mechanism, the fuel flowing through the housing past the motor to the outlet. A module including a commutation circuit for the d.c. motor is sealed in the housing from the fuel which flows therearound and cools the module. The module is constructed with an injection-molded casing around the circuit which is connected to stator windings of the motor and to an outside power supply.
    • 一种用于内燃机的电动燃料泵,其中泵机构设置在用于将燃料从壳体的入口排出到泵的壳体中。 一个d.c. 壳体中的电动机驱动地连接到泵机构,燃料流过壳体经过电动机到出口。 一种模块,包括用于直流的换向电路。 电机从外部流入的燃料密封在壳体中并冷却模块。 该模块由围绕电路的注塑外壳构成,其连接到电动机的定子绕组和外部电源。
