Abstract

PURPOSE: To prevent lubrication failure and seizure trouble based on a pressure drop of lubricating oil discharged from a centrifugal pump when the rotation speed of a compressor is low.
CONSTITUTION: A cylinder chamber 33 whose boundary is fixed by surrounding the lower end part of a rotary shaft 5 with a cylinder 30 is divided in to an oil sucking chamber 38 and an oil discharging chamber 39 with a pair of blades 36 that protrude from and retriet to pair of slots 35 drilled at the lower end of the rotary shaft 5. Lubricating oil 81 reservoired at the lowermost part inside a closed housing 8 is sucked into the oil sucking chamber 38 by the rotation of the rotary shaft 5 and the lubricating oil inside the oil discharging chamber 39 is discharged to a centrifugal pump 51.
