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.
