Abstract
A fluid machine and method of operating the same includes a pump portion having a pump impeller chamber, a pump inlet and a pump outlet, a turbine portion having a turbine impeller chamber, a turbine inlet and a turbine outlet and a shaft extending between the pump impeller chamber and the turbine impeller chamber. The fluid machine also includes a first bearing and a second bearing spaced apart to form a balance disk chamber. A balance disk is coupled to the shaft and is disposed within the balance disk chamber and a turbine impeller coupled to the impeller end of the shaft disposed within the impeller chamber. A first thrust bearing is formed between the balance disk and the first bearing. The thrust bearing receives fluid from at least one of the pump outlet or the turbine inlet.
