ABSTRACT:
The invention pertains to the method and apparatus of compensating for the axial bearing load forces imposed upon rotary joints conveying a pressurized fluid medium, such as steam, by imposing an axial force on the rotary joint housing proportional to the pressure within the rotary joint by use of a distinctively different pressurized medium than that comveyed by the joint, such as compressed air. An expansible chamber motor capable of imposing an axial force on the rotary joint utilizes compressed air whose pressure is controlled by a sensing and regulating system responsive to the pressure within the rotary joint.
