ABSTRACT:
A centrifugal oil pump for a compressor having improved head and flow performance in which a plurality of tunnels extend radially outward and angularly upward from the face of the impeller and convey oil to the perimeter of the drive shaft during operation. The oil is collected in a chamber of a housing around the bottom of the crankshaft, flows through a channel of an end plate and is transmitted upwardly in a bore of the crankshaft. Entrained gases are vented from each inlet hole to a common annular ring, and through a vent from the annular ring upwardly in the crankshaft.
