  • Fluid pump with flow impedance member
    Patent number: 10557479
    Abstract: A fluid pump includes an inlet for introducing fluid into the fluid pump and an outlet for discharging the fluid from the fluid pump. A motor is included having an armature which rotates about an axis. The motor also has 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 is rotated by the armature and pumps the fluid from the inlet to the outlet. A flow impedance member extends 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.
