  • Publication number: 20230012331
    Abstract: One aspect of a pump of the present invention includes a rotor rotatable about a central axis, a stator assembly located radially outside the rotor and surrounding the rotor, a pump unit connected to a first side in an axial direction of the rotor, a support member including a rotor accommodating portion, the rotor accommodating portion being located radially inside the stator assembly and accommodates the rotor therein, and a resin housing in which the stator assembly and the support member are molded. The rotor accommodating portion includes a lid portion that covers the rotor from a second side in the axial direction, and a tubular portion that is located between the rotor and the stator assembly in a radial direction and is open to the first side in the axial direction. The stator assembly includes a stator core having an annular shape, a plurality of coils mounted on the stator core, and a stator cover that covers the plurality of coils.

  • Patent number: 7559310
    Abstract: An engine control fuel pump apparatus is provided with a low load fuel pump control section, a high load fuel pump control section and a subordinate pump drive section. The low load fuel pump control section controls a main fuel pump for supplying fuel to an engine when an engine operating condition indicates that the engine is operating with a low load. The high load fuel pump control section controls the main fuel pump and a subordinate fuel pump for supplying fuel to the engine when an engine operating condition indicates that the engine is operating with a high load. The subordinate pump drive section drives the subordinate fuel pump for a prescribed period of time when a rotational speed of the engine is equal to or higher than a prescribed rotational speed while the engine is operating in an low load operating region in which the low load fuel pump control section controls the main fuel pump for supplying fuel to the engine.
