Abstract
This hydraulic machine () has a wheel () mounted to move in rotation relative to a stationary structure () and about a stationary axis of rotation (X), the wheel () being designed to pass a forced flow (E) of water therethrough. A hydrostatic bearing (), provided between firstly an element () constrained to rotate with the wheel () and, secondly a portion () of the stationary structure (), is disposed between a first zone (Z) of the machine, which zone is in fluid communication with the forced flow (E) and in which zone, during operation, a pressure prevails that is similar to the pressure of the forced flow, and a second zone (Z) of the machine that is isolated from the forced flow by said bearing.
