1. A method for cooling and for optimizing the operating pressure of gas bearings used to support a rotating group that includes a shaft and a compressor, the method comprising the steps of:(a) supplying a portion of compressed air from the compressor to a cooling circuit, thereby creating an air flow in the cooling circuit; (b) splitting the air flow in the cooling circuit, thereby creating at least a first separate flow path and a second separate flow path in the cooling circuit; (c) flowing the air in the first separate flow path through at least one of said gas bearings and then through a first flow control device; and (d) flowing the air in the second separate flow path through at least another one of said gas bearings and then through a second flow control device.
