In a self-tightening type sealing device according to the present invention, not only a sealing member is tightened by an internal pressure, but also a tightening force imparting device which tightens the sealing member separately from the internal pressure is provided so as to be remotely operable by a controller. This construction remedies drawbacks involved in manual operation of the tightening force imparting device.

Self-tightening type sealing device

An isostatic press includes a heat insulator that forms a working zone which contains a workpiece, a high pressure vessel that covers the heat insulator, a heating unit that heats the high pressure vessel, and a pressure medium supplying device that can supply an interior of the high pressure vessel with the pressure medium A pressure medium introducing space communicates with the working zone via a communication hole formed on a top portion of the heat insulator. The pressure medium supplying device communicates with the pressure medium introducing space via a pressure medium introducing opening formed on a bottom portion of the high pressure vessel.
