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

FIELD: process engineering.

SUBSTANCE: invention relates industrial equipment intended for processing parts in gas atmosphere at simultaneous effects of high pressure and temperature. Proposed gasostatic extruder comprises load bearing base, reactive medium container closed by top and bottom plugs, gas control valves communicated by gas pipelines and made up of body with seat, needle, servo drive, pressure spring and unloading cylinder with its rod arranged on valve needle. Note here that body of every valve has groove to accommodate cylindrical insert connected with gas pipelines. Said insert is made from material insensitive to reactive working medium effects. Note that valve seat is arranged in insert. Unloading cylinder is arranged inside aforesaid spring and coupled with servo drive by quick-release bayonet lock. Said servo drive is jointed to valve body by two pins arranged to adjust needle action on valve seat. Note also that valve incorporates cross piece to lock insert inside aforesaid groove that is fitted in valve body slot. Container top plug has gas inlet.

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