Abstract
A compressor assembly including a crankshaft with an axial oil passageway therein. An oil pump booster is mounted on the crankshaft to increase the oil flow rate through the axial oil passage. The oil pump booster includes a counterweight and an enclosed channel extending in the radial direction communicating with the axial passageway of the crankshaft. During rotation of the compressor crankshaft, the radial oil channel is likewise rotated creating a centrifugal force or reduced pressure area to increase the oil flow through the axial passage.
