Abstract
FIELD: hydraulic automatic control systems. SUBSTANCE: pilot valve has control stage 1 and controlled stage 2. Gate 3 in control stage has projections 4, 5, is located between nozzles 6, 7, is installed in pilot valve housing on bands 8, 9 and is coupled with movable member of electromechanical transducer 10, with form 11 of movable coil 12 located in circular clearance 13. Nozzles 6, 7 are connected to pressure source through restrictors 14, 15 and channels 16, 17, 18, 19 communicating with end face chambers 20, 21 of spool 22. Return chamber 23 is hermetically sealed by diaphragms 24, 25 and is placed in communication with reservoir through channel 26. Gate 3 is held in neutral position by springs 27, 28. Clearance between end face surfaces can be adjusted by turning in or out along thread 31. EFFECT: enhanced reliability of servomechanism. 1 dwg
