    摘要： A fluid pump includes an inlet for introducing fluid into the fluid pump; an outlet for discharging the fluid from the fluid pump; a motor having an armature which rotates about an axis such that the armature is supported at one end by a first bearing and at second end by a second bearing, the motor also having a stator which circumferentially surrounds the armature such that a fluid passage is defined radially between the armature and stator through which the fluid flows from the inlet to the outlet; a pumping arrangement which is rotated by the armature and which pumps the fluid from the inlet to the outlet; a flow impedance member extending axially in the fluid passage which impedes circumferential flow of the fluid within the fluid passage, thereby generating a pressure gradient circumferentially within the fluid passage which applies a lateral force to the armature.

    摘要： A projection of a suction end cover has an outer circumferential surface serving as a sealing surface to be connected with a suction filter. A suction flow path is configured by an introduction hole in a bottomed cylindrical shape, and a connection hole. The introduction hole extends from the distal end of the projection of the suction end cover toward a pump chamber. The connection hole connects the introduction hole and the pump chamber. The introduction hole has a bottom surface that is located axially between a slide inner surface of the suction end cover and a bottom surface of a recess. The suction flow path can be increased in sectional area enough to reach a position in immediate front of the pump chamber with no change in outer diameter of a housing. By reducing fuel flow speed in the suction flow path and suppressing negative pressure in the suction flow path, generation of fuel vapor in the suction flow path can be inhibited even in a large flow rate area.

    摘要： An ECU of a fuel pump executes a feedback control to drive a motor part and sets a rotation speed of an impeller to become a rotation speed corresponding to the target fuel pressure. The ECU detects whether a vapor is generated in a fuel of a pump chamber of the fuel pump, based on a fuel pressure detected by a pressure sensor. When a generation of the vapor is detected, the ECU sets a rotation speed of the impeller to be higher than the rotation speed under a normal control for a predetermined time with a result that the vapor in the pump chamber and a fuel flow channel is discharged into a vapor discharge hole. Thus, the vapor of the pump chamber is discharged from the vapor discharge hole to an outside of the fuel pump.
