Abstract
The disclosure concerns a hydroelectric machine including a tube-type hydraulic machine having a bladed wheel which rotates about a horizontal axis and is provided with fixed blades which are encircled by, and connected with, a rim to which the rotor of a surrounding electrical machine is attached. The wheel, rim and rotor form a single rotating unit which is supported in the radial direction without physical contact by at least two hydrostatic centering supporting devices and at least one hydrostatic damping device. At least one hydrostatic load-beaing device may be included for accepting without physical contact a constant portion of the weight of the rotating unit. In addition, the machine may include hydrostatic supporting devices, of the centering type or of both the centering and the damping type, for accepting without physical contact the axial thrusts imposed on the rotating unit.
