Abstract

PURPOSE: To perform satisfactory separation of oil without causing the necessity for auxiliary equipments like oil separator or oil cooler, by providing oil separating and oil supplying means in a compressor's own body.
CONSTITUTION: Perpendicularly extending through a fixed scroll end plate and frame from the bottom surface of an oil sump groove 32, oil drain holes 35, 36 are provided, through which accumulted oil 33 flows to space 43a in the upper portion of a motor. Gas is once guided to the outside of a chamber 13 from a delivery gas take-out pipe 40, cooled and then returned to the inside of the chamber 13 through a return pipe 41, thus cooling and reseparation of oil can be performed. A delivery chamber 31, being provided in the opposite side to a lapping face of the fixed scroll end plate 3, permits the satisfactory separation of oil from gas in the enclosed space formed by the chamber 13 and a cover 30.
