Abstract

A fluid bearing system for journalling a shaft against radial and/or axial loads. The described bearing consists of a housing having at least one fluid compression chamber. The housing surrounds the shaft and is provided with at least one portion which is stationarily fixed with respect to the shaft. Inlet means are provided through the stationary portion for the introduction of air or liquid. A ring securely fixed to the shaft for rotation therewith extends in opposition to the stationary portion. The ring forms with a surface of the stationary portion a throttling gap between the inlet and the compression chamber by which the restriction of fluid flow is accomplished.
