Abstract: A lubricating device, especially for use with a hermetic motor compressor unit, having a vertical shaft extending downwardly into a lubricant sump. The lubricating device comprises a pick-up tube having a larger diameter upper cylindrical portion open at the upper end thereof and adapted for being fitted into a central bore in the shaft, a smaller diameter lower cylindrical portion adapted to be immersed in fluid in the sump, a tapering transition region connecting the upper and lower cylindrical portions, an inlet port extending axially into the lower end of the lower portion, and the pair of diametrally opposite ribs on the lower cylindrical portion comprising ridges on the inner surface and corresponding hollows on the outer surface thereof.

Abstract: A lubricating device, especially for use with a hermetic motor compressor unit, having a vertical shaft extending downwardly into a lubricant sump, and in the lower end of which shaft is a device having an inlet in the lower end and operable as the shaft rotates for propelling the lubricant upwardly along a hollow passage in the shaft and into a channel formed in the outside of the shaft and disposed within the axial limits of the bearing which supports the shaft.
