Hydrostatic supporting device

Abstract From the Canadian patent

The disclosure concerns 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 …
