APPARATUS FOR STABILIZING GAS PRESSURE Russian patent published in 1995 - IPC

FIELD: machine engineering. SUBSTANCE: apparatus includes arranged in the housing 28: the inlet chamber 1 with an input valve (gate 2-nozzle 3), the output chamber 4 with the diaphragm 5, the rod 6, the booster chamber 7 with an input system nozzle 8 gate 9, the last being made of magnetostrictive material, the coil 10, the magnetizing device 11(a permanent magnet), the adjusting screw 12. The output chamber has the nozzle 13, the gate 14, the coil 15, the adjusting screw 17, forming the gap S₂.. The housing of the apparatus is provided by the chamber 18 of the pressure pickup 25, the chamber 18 being connected with the third input of the control unit 24, whose first and second inputs are connected respectively with the coils 10, 15 of the input and output valves of the booster chamber 7. EFFECT: enhanced accuracy of gas pressure stabilization. 1 cl, 1 dwg
