ABSTRACT:
The invention concerns hydrostatic bearings supplied with fluid under pressure for a shaft rotating at high speed in a fixed bed, with the goal of reducing the power dissipated by shear of the fluid in the said bearings.
According to the invention, a sleeve (5) is disposed coaxially to the shaft (1) in a chamber arranged for this purpose between the bed (3) and the shaft (1), with apertures being arranged respectively in the shaft and in the bed, opposite the sleeve on one side and the other, in such a way that a movement in rotation can be imparted to the sleeve (5), the structure being particularly applicable to fluid pumps.
