ABSTRACT:
A parallel operation compressor type refrigerating apparatus is disclosed which has first and second compressors connected in parallel with each other by a pipe, each having the inside of its crankcase separated into a motor chamber and a compressing element chamber by a partition provided with a pressure equalizing opening and a lubricant equalizing nonreturn valve allowing lubricant passage only from the motor chamber side to the compressing element chamber side, and which comprises a means provided at the end of a suction pipe of a refrigeration cycle system to separate the refrigerant gas circulating within the suction pipe into a lubricant and a gas, a first branch pipe to supply a portion of said gas to the first compressor, a second branch pipe to supply the rest of the gas and the lubricant to the second compressor, a pressure and lubricant equalizing pipe connecting together the lubricant sinks of the two compressors, and a nonreturn valve provided in the pressure and lubricant equalizing pipe to block the gas flow from the first to the second compressors.
