Abstract

PURPOSE: To prevent passage of refrigerant gas through a non-operating compressor by inter connecting oil receivers of cross compound compressors via a U type oil equilizing pipe, with respect to those which operate in parallel a plural set of refrigerant compressors.
CONSTITUTION: An oil equalizing pipe 18 which interconnects bottom oil receivers 17a and 17b of crankcases 6a and 6b of compressors 1a and 1b are shaped U type. When the compressor 1b is not in operation, pressure in the crankcase 6a of operating compressor 1a becomes lower than pressure in the crankcase 6a of non-operating compressor 1b due to pressure loss in a suction side connecting pipe 4 and an anti-suction valve 5a. Height H of a U type oil equalizing pipe 18 is to be made higher this pressure loss. Thereforce, since the lower part of the U type oil equalizing pipe 18 is filled with oil, refrigerant gas does not flow into the oil equlizing pipe 18.
