Abstract
A rotating-shaft hydrostatic bearing of the type comprising a support circuit including opposed support chambers around the shaft receiving fluid under pressure and having a constant leakage with respect to the shaft, a radial position detection circuit for the shaft in the bearing including opposed detection chambers around the shaft receiving fluid under pressure and having a constant leakage with respect to the shaft, a device for servoing the shaft in position activated by the detection circuit and acting on the support circuit, the servoing device comprising a distributor with mobile element adapted to supply the opposed support chambers by the intermediary of constrictions varying in the inverse sense on one side or the other of its equilibrium position, the mobile distributor element being integral in motion with a mobile corrector element subjected to the opposed actions of the fluid pressure prevailing in the opposed chambers of the detection circuit. The mobile annular element of the distributor is surrounded by a second annular element forming with it chambers connected to the detection chambers and delimiting the opposed zones, this second annular element itself being s…
