Abstract

A SCROLL COMPRESSOR (20) INCLUDES AN OIL SUPPLY CROSS-HOLE (40) EXTENDING RADIALLY OUTWARDLY TO THE OUTER PERIPHERAL SURFACE OF THE BASE OF THE ORBITING SCROLL. THE CROSS-HOLE SUPPLIES LUBRICANT AGAINST THE CRANKCASE TOWERS (52,54) SUCH THAT LUBRICANT IS SUPPLIED TO BOTH THE OLDHAM COUPLING (49) AND THE SEALS FOR THE BACKPRESSURE CHAMBER. THE CROSS-HOLE IS PREFERABLY POSITIONED TO BE BETWEEN 80° AND 90° DOWNSTREAM FROM THE BEGINNING OF THE ORBITING SCROLL WRAP. IN THIS POSITION, ADEQUATE OIL WILL BE SUPPLIED TO LUBRICATE THE OLDHAM COUPLING (49) AND THE SEAL, WHILE AT THE SAME TIME, IT IS UNLIKELY THAT AN UNDUE AMOUNT OF LUBRICANT WILL BE ALLOWED INTO THE SCROLL COMPRESSOR CHAMBERS.(FIG 2)
