ABSTRACT:
In the embodiment depicted, the system comprises a gas compressing arrangement of first and second rotary compressing stages with an intercooler and an aftercooler for condensing and removing moisture from the compressed gas product. In order to cool the gas compressor, generally, and the second-stage rotor shafts in particular, the cooled, de-moisturized, compressed-gas product is used. Thus, the second-stage rotor shafts are axially bored or hollowed, and a tube is supported within the bore. The tube is through-connected with the outlet of the aftercooler to admit the cooled, compressed gas product into the bore, and, in turn, the compressed gas product is discharged from the bore. Accordingly, the cooled, compressed gas product is cycled through the bore, constantly to cool the shafts all the while that the compressor is running, or under load.
