ABSTRACT:
Hydrostatic support apparatus for a movable part comprises a bearing plate and a support member which are movable relatively to each other and to a base and define a pressure chamber. The plate has a bearing surface containing a bearing pocket connected by a choke bore with the pressure chamber, is urged toward the movable part by pressure in that chamber, and is urged toward the support member by a spring. The support member is urged toward the movable part by a second spring or by a second spring and a hydraulic cylinder. The construction enables the bearing plate to be resiliently pressed toward the movable part during normal operation, but causes retraction of that plate upon a loss of pressure in the pressure chamber, to thereby prevent wear.
