| 1. A method of pressure balancing across a bearing adjacent to a pressure differential, the pressure differential including
a first pressure side on a first side of said bearing and a second pressure side on a second side of said bearing, comprising:
providing a bypass port around said bearing for allowing a fluid flow from the first pressure side to the second pressure
side, wherein said bypass port is configured in said bearing and provides a passage around an outer periphery of said bearing.
