Abstract

PURPOSE: To reduce drastically loss of a gear train, due to friction with gas, revolving at high speed in a gear box equipped on a rotary fluid machine having a multiplying device by means of a gear train, by constituting so that inside the gear box can be held at low pressure.
CONSTITUTION: This turbo refrigerator is, for ex., composed of an electric motor 1, a multiplying device 2 consisting of a gear wheel 5 and a pinion 9, a compressor 3 including an impeller 10, an inlet vane 14 and a diffuser 14d, a condenser C including two or more heat exchange tubes 18, a depressurizing means EXP consisting of a float 20 and a valve 21 fixed to the float 20, and an evaporator E including two or more heat exchange tubes 24 and a flushing duct 27. In this case, the inside of the gear box 6 of the multiplying device 2 shall be communicated to the inside of the shell 16 of the condenser C with a piping 29 and a vacuum pump 31 and a valve 30 are interposed on the midway of the piping 29 to hold inside the gear box6 at low pressure by the action of this pump 31.
