METHOD OF CONTROL OF WORKING PROCESS OF AERODYNAMIC FLUIDIC COMPLEMENT FLIP-FLOP SYSTEM Russian patent published in 1995 - IPC

FIELD: pneumatic control components. SUBSTANCE: in aerodynamic fluidic complement flip-flop based on fluidic elements with intrinsic hydromechanical feedback a pressure difference between the inlet ports of active flip-flop is built up, in one of its inlet ports expansion pressure is built up, and in the other inlet port of the active flip-flop high pressure is built up by directing part of the reflected flow cut off by deflector from the power jet of the active flip-flop to this port, with simultaneous formation in reversing passages and working chamber of the passive flip-flop of ordered motion of the working medium flow, which deflects and directs the signal jet, applied to the complementing input of the aerodynamic flip-flop to reverse the power jet in the active flip-flop. EFFECT: enhanced reliability of operation of aerodynamic complement flip-flop by forming such a pressure difference at active flip-flop control inputs, which prevents false operations of passive flip-flop, simplifies its tuning and matching with other devices, enhances reliability of operation of the entire device. 1 dwg
