ABSTRACT:
Hydrostatic supporting apparatus which supports, without physical contact, a mobile part which moves relatively to a load-bearing part. The apparatus comprises a supporting piston which has at least one hydrostatic bearing pocket which provides a pressure cushion through which the mobile part is supported, and which is urged toward the mobile part by a controlled pressure which increases and decreases, respectively, as the piston moves toward and away from the load-bearing part. Preferably, pressure control is effected by a throttle valve interposed either in a supply path leading from a source of pressure medium to the pressure chamber of a hydraulic supporting motor, or in a feed passage leading from that pressure chamber to the bearing pocket. The pressure cushion of the supporting piston may act directly upon the mobile part, or it may carry an auxiliary hydrostatic supporting element which has its own supply of pressure medium and provides a second pressure cushion which actually supports the mobile part. The apparatus may also include a safety device which serves to maintain supporting pressure for the piston upon failure of the main pressurizing circuit.
