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

FIELD: metallurgy.

SUBSTANCE: invention refers to equipment for processing items for industrial use out of discrete and solid materials at simultaneous or combined effect of high pressure and temperature created in working chamber of gas-static extruder. Here is disclosed the gas-static extruder consisting of a power bed and a container closed on ends with an upper and lower plugs and coupled with a gas system and system of vacuumising, gas inputs of which are separated. Also the gas input and a pipeline of the vacuumising system have expanded port areas. The system of vacuumising is equipped with an input gate valve with expanded port area; the gate valve is mounted on an upper plug. A sub-valve cavity of the valve is coupled with the gas input made in the upper plug, with a vacuum pump with filter connected to an over-valve cavity of the input gate valve and membrane gates with expanded port areas.

EFFECT: reduced time of vacuumising, avoiding use of high pressure pipeline, reduced dimensions and metal input of gate valves, raised efficiency and reduced prime cost.
