Restrictors and Compensation of Hydrostatic Bearings

Basic description A hydrostatic bearing requires a flow control mechanism so that the lubricant pressures in the bearing can increase in response to increased load (Rowe 1983, 1989).If the supplied recess area must carry loads independently, each recess or entry port requires a flow control mechanism. A simple laminar flow
