MEANS UTILIZING COMPRESSED AIR FOR CONFINING A PRESSURIZED OIL FILM BETWEEN RELATIVELY MOVABLE BEARING SURFACES

摘要

A pressurized oil film is built up in a region between relatively movable bearing surfaces by means including a pressurized oil supply line and an oil return line. Compressed air is caused to impinge on the edges of the oil film region to provide a pneumatic pressure threshold for confining the extent of the region and preventing leakage of the oil.
