Definitions

  • FIG. 3 which shows still another embodiment of the invention wherein a radial type of electric motor 3 having a coolant jacket is employed
  • the housing 4 of electric motor 3 is provided with a jacket 28 around the periphery thereof so as to form a tightly closed hollow chamber 27, the interior ofwhich is communicated with an exhaust or discharging conduit 29 extending from the outlet 5 of the low stage compressor 1.
  • a suction conduit 30 led from the hollow chamber 27 is connected'to the suction inlet 6 of the high stage compressor 2.
  • a branch conduit 25 branched from the liquid conduit 8 is additionally communicated with the hollow chamber 27 of the jacket 28 by way of a temperature responsive expansion valve 7 which in turn has a temperature sensing member 26 for detecting the temperature of exhaust gas from the high stage compressor 2.
  • the remaining arrangement of the apparatus is same as that of the embodiment shown in FIG. 1. In operation, the cooled exhaust gas from the I compressor 1 is supplied to the hollow chamber 27 formed by the jacket 28 to thereby cool the electric motor 3.
  • Two-stage compression apparatus as set forth in claim 1, wherein said compressors for low and high compression stages are coaxially arranged with interposition of said motor.
