ABSTRACT:
An oil separator used in a refrigerating system. The oil separator comprises a body for forming a centrifugal oil separating chamber and an oil storage chamber, with a separating plate dividing the chambers. An inlet passage is connected tangentially to the oil separating chamber, to cause a swirl in the chamber, and a medium outlet passage extends inwardly from an end wall into the oil separating chamber. An oil outlet passage(s) is provided in the separating plate at a position near a periphery thereof. The oil separator body is formed integrally with the compressor housing and a ring member is fitted in an inner surface of the oil storage chamber, and a helically shaped narrow groove is provided on the outer surface thereof to form an oil returning passage. Also, the oil outlet passage can be provided in the separating plate at a position lower than a highest level of the oil storage chamber, thereby allowing the chambers to be arranged in a horizontal side by side relationship.
