Abstract

PURPOSE: To achieve forced fluid lubrication for the bearing, without providing a special flow passage to the bearing, by making a crevice between the outer wall of the circular opening in the pump casing and the first and the second bearing parts member outer peripherals.
CONSTITUTION: Through the crevice between the circular opening 6 in the pump casing 1 and the ecdentric ring 22 and the outer peripherals of the first and the second bearing members 13, 21, the fluid is sucked in to the fluid passage 24 and is pressed on the fluid passage 25 side. The fluid flows through the hole 11 on the first bearing member 13 side into the magnet chamber 12, and flows further through the crevice between the bearing 14 and the shaft 30 and the slit 18 in the end surface bearing 17, and then, the fluid is returned to the pump chamber through the space between the side plate 34 and the first bearing member 13. Also, the second bearing member 21 side generates the similar flow through the crevice 42 in the cap. By so constituting, the forced lubrication to the bearing becomes possible without providing any special passage.
