Abstract:
A hydrostatic bearing for supporting a shaft, comprising:a bearing collar having a centerplane and a radially inner bearing surface that circumscribes the shaft to define a film annulus;an array of discrete pockets distributed circumferentially along the bearing surface, each pocket communicating with first and second vent regions by way of the film annulus, the vent regions being axially spaced from each other on axially opposite sides of the pocket array; andat least one directionally selective fluid injection passage associated with each member of a selected subset of the pockets, each directionally selective injection passage having a discharge opening for injecting a stream of pressurized fluid into the associated pocket so that the stream of fluid issuing from each directionally selective passage has an axial directional component directed toward a common one of the vent regions.
