Abstract: There is disclosed herein a lubrication system for a compressor which includes means for directing lubricant supplied to an upper bearing across the working surfaces thereof and returning this lubricant directly to the oil sump of the compressor thereby preventing lubricant from entering the compressor means which may result in slugging thereof. This oil return means includes an upper bearing which is provided with grooves on the working surface thereof which direct excess oil supplied to the bearing back to the oil sump while allowing a lubricating film of oil to remain between the adjacent bearing and crankshaft surfaces.
