Abstract

A SCROLL COMPRESSOR (20) HAS A UNIQUE OIL SUPPLY PORT (34) FOR SUPPLYING LUBRICANT TO BOTH THE SEALS AND THE OLDHAM COUPLING. THE OIL SUPPLY PORT (34) IS POSITIONED AT A LOCATION SUCH THAT IT WILL NOT LIKELY RESULT IN UNDUE AMOUNTS OF LUBRICANT BEING ENTRAINED INTO THE REFRIGERANT LEADING INTO THE COMPRESSION CHAMBERS. THE PRESENT INVENTION IS THUS AN IMPROVEMENT OVER THE PRIOR ART. (FIGS. :1 & 4)
