MODULAR CATHODE-COMPENSATOR Russian patent published in 2011 - IPC F03H1/00 

FIELD: engines and pumps.

SUBSTANCE: invention refers to plasma engineering and can be used both as part of space electrojet engines for neutralisation of ion beam at their ground tests and field operation, and in process plasma sources used for ion-plasma treatment of surfaces of various materials in vacuum. Modular cathode-compensator containing housing with end wall, emission assembly with outlet hole and gas supply tube, igniter electrode connected through insulator and holder to mounting flange and seating bracket with externally fixed holes differs by the fact that on the end wall of the housing coaxially to longitudinal axis of cathode-compensator there made is projection fixing in radial direction, and between emission assembly and side wall of the housing there formed is gap, the end of which is located in middle part of emission assembly; in addition to the external housing side there introduced is hollow rotor with thin-wall edge which is connected to the housing projection, and on the other side with front flange which is adjacent to additional snap diaphragm connected to the end face of side wall of the housing, the peripheral part of which is arranged between mounting flange of igniter electrode and end flange of rotor, which are fixed on ends of additional elastic pins which are arranged about rotor coaxially with longitudinal axis of cathode-compensator and connected with their other ends to seating bracket.

EFFECT: invention allows improving mechanical durability and reliability of the construction at increased mechanical impacts.
