ABSTRACT:
Hydrostatic apparatus for supporting a mobile part which moves relatively to a foundation comprises a bearing shoe having a bearing face containing a pressure pocket, and a hydraulic servomotor which exerts on the shoe a force urging it toward the mobile part. A support element connected with the shoe and the foundation positively holds the shoe against movement in at least one direction along its supporting axis, and its restraint is so correlated with the pressure forces acting on the shoe that the latter is rendered non-displaceable. Depending upon the relative magnitudes of the forces developed by the servomotor and by the pressure acting on the bearing face, the support element may normally be unloaded, loaded in tension or loaded in compression. In the first case, the support element prevents movement of the shoe in opposite directions along the support axis, whereas in the second and third cases it may permit movement of the shoe toward and away from the foundation, respectively.
