Abstract
A thermopneumatic support device for providing support over a range of positions for objects, such as high temperature steam piping, subject to temperature changes and thus to changes in position resulting from thermal expansion or contraction. The device utilizes the heat energy of the object being supported in order to provide the necessary power to move the object over a range of positions. The heat energy from the object being supported provides the power for moving the thermopneumatic support in direct proportion to the expansion or contraction resulting from the variation in temperature of the object being supported. The device comprises pneumatic actuating means comprising a sealed chamber containing a fixed mass of a compressible fluid which is in thermal contact with the object being supported. Pressure changes in the enclosed compressible fluid results in direct proportion to pressure changes of the fluid which in turn causes movement of the support means in response to temperature changes in the object being supported. There are coupling and linking means provided between the support means and the pipe and the support means and a stationary support respectively.
