ABSTRACT:
A system and process of parallel compressors for compressing fluids miscible with oil. The present invention utilizes parallel-coupled compressors, wherein each compressor comprises a crankcase chamber, discharge chamber, suction chamber, and ejector which operate independent of one another. Means are provided for coupling the ejector in the return of the lubrication pump oil within the crankcase chamber and the maintenance of that oil level in all the crankcase chambers regardless of each compressor capacity and quantity with which they are operating or are not operating. The transference of suction chamber oil to crankcase chamber is performed by the ejector via energy from the lubrication pump contained within each crankcase chamber. Further, transference of oil from suction chamber to crankcase chamber via an ejector performs all necessary equalization functions.
