ABSTRACT:
A pressure balance bearing providing a hydrostatic bearing film, which is connected to maintain a load or device in a constant position in relation to a reference or support surface. Several support bearings are plumbed together so that there may be cross flow between the bearings. An external control valve is mounted on the member and senses the relative position of the object. The valve in turn adjusts the flow of oil into the bearings as a function of changes of relative position of the object and reference or support surface. As shown, a large mass is supported on the pressure balance bearings and is capable of bilateral movement. The mass is supported on a plurality of bearings using three control valves arranged in a tripod configuration.
