TWO-CHAMBER GASOSTATIC EXTRUDER Russian patent published in 2010 - IPC B22F3/15 

FIELD: process engineering.

SUBSTANCE: invention relates to industrial equipment intended for processing parts in gas atmosphere at simultaneous effects of high pressure and temperature. Two-chamber gasostatic extruder comprises container with top and bottom plugs that form working chamber, load bearing base, partition dividing said working chamber into outer chamber with neural medium and inner chamber with reactive working medium, system of inert and reactive working media sources with shut-off valves communicated with aforesaid sources, heating and control systems. Said container represents a unit consisting of three thin-wall sleeves pre-assembled with interference fit to produce uniform distribution of compression strains therein in winding high-strength tape on sleeves unit outer surface to make a belt. Inner sleeve surface and top surfaces of top and bottom plugs are furnished with copper coating. Said partition is made thin-walled and tight. Control system can maintain outer chamber neutral medium pressure above working pressure in inner chamber and incorporates device to synchronise pressure in said inner and outer chambers. Said system represents three transducers, interconnected and connected with control system processor.

EFFECT: reliable design, higher safety, antirust protection, reduced weight of container and base.
