Abstract
Abstract A fluid bearing system for journalling a rotatable shaft in which an annular housing is fixed about the shaft and is provided with an inlet for the supply of fluid under pressure. At least one bearing compression chamber is formed in the housing and/or the shaft and is distributed about the periphery of the shaft. The housing and the shaft form an integrated throttle control means in which a restrictor opening and a discharge opening is formed between the housing and the shaft for the flow through of fluid from the inlet. The openings are simultaneously varied relative to each other in an opposing manner as a function of the size and distribution of the load placed on the shaft.

Claim 1
Independent Claim
157 words
A fluid bearing for a shaft comprising an annular housing located about said shaft, said housing and said shaft defining at least one fluid compression pocket distributed about the periphery of said shaft, an inlet for the supply of fluid under pressure to said compression pocket and control means for regulating the flow of pressure to and from said pocket comprising an annular recess formed in said housing, a pair of spaced disks integrally formed with shaft and extending radially outward into said recess, an annular ring integrally formed with said housing and extending radially inward between said spaced disks, the axially opposing surfaces of said ring and said disks forming restrictor inlet openings and the axially opposing surfaces of said disk and said housing forming discharge openings, said restrictor inlet and discharge openings being simultaneously varied relative to each other in the opposite direction as a function of the size and distribution of the load thereon.
