DEVICE FOR ACTUATING MEDIUM SUPPLY FOR PLASMA ACCELERATORS Russian patent published in 2000 - IPC

FIELD: automatic control, in particular, regulation of actuating medium supply for stationary plasma engines of spacecrafts, supply of plasma for ground technological sources. SUBSTANCE: device has actuating medium source, which is connected to input of device for regulation of actuating medium supply, which has input pipe, which is connected to main and redundant reduction mechanisms, each of which has serial circuit of mechanical pressure regulator, which has actuating medium reset pipe, which also has protection valve, and electromechanical pressure regulator. Output of protection valve is connected to output electromechanical pressure regulator. Outputs of electromechanical pressure regulators of main and redundant reduction mechanisms are joined and are connected to output pipe of device for regulation of actuating medium supply. Output of latter device is connected to pipe for actuating medium supply to plasma accelerator. EFFECT: detection of complete or partial fault of mechanical pressure regulator, when this event happens, decreased losses of actuating medium through protection valve. 1 dwg
