TWO-STAGE SCREW COMPRESSOR AND A REFRIGERATING DEVICE, CAPABLE OF PROVIDING A TWO-STAGE SCREW COMPRESSOR WITHOUT LEAKAGE OF COMPRESSED FLUID

摘要

PURPOSE: A two-stage screw compressor and a refrigerating device are provided to completely prevent leakage of compressed fluid.;CONSTITUTION: A two-stage screw compressor and a refrigerating device include a one-stage compressor(2), a two-stage compressor(3), a motor(4), and a box(28). The one-stage compressor compresses fluid. The two-stage compressor more compresses the fluid compressed by the one-stage compressor. The motor is contained in a casing(5) by driving the one-stage compressor and the two-stage compressor. The box functions as a flow path which connects an outlet of the one-stage compressor with an inlet of the two-stage compressor.;COPYRIGHT KIPO 2010
