摘要： A flueric multiplier stage is disclosed which comprises two fluid amplifiers whose power streams are respectively connected to opposite sides of a first pressure differential signal and whose control ports are connected in parallel across a second pressure differential signal. The output receivers of the fluid amplifiers are cross-connected such that the left receiver of the first amplifier is connected to the right receiver of the second amplifier, the structure described being adapted to provide a push-pull output signal which is proportional to the product of two push-pull input signals. Circuits incorporating the basic multiplier stage are also disclosed, as are circuits in which the output is restricted to respond to a singularly directional input.

摘要： A PRESSURE RATIO SENSOR OR TRANSDUCER FOR GENERATING AN OUTPUT PROPORTIONAL TO P2/P1 IS DISCLOSED WHICH COMPRISES A FLUID SIGNAL SUMMING DEVICE, A FLUERIC DYNAMIC COMPENSATION CIRCUIT, A MECHANICAL VALVE, AND A FEEDBACK LOOP P2 PROVIDES AN INPUT TO THE SUMMING DEVICE, WHILE P1 PROVIDES AN INPUT TO THE MECHANICAL VALVE. THE MECHANICAL VALVE IS BASICALLY A SPOOL WITH THREE LANDS AND AN INTEGRAL PISTON OF LARGER DIAMETER. THE OUTPUT OF THE FLUERICS IS A DIFFERENTIAL PRESSURE WHICH IS APLIED ACROSS THE PISTON AREA TO DRIVE THE SPOOL. AS THE SPOOL MOVES, EACH OF THE THREE LANDS CRSSES OVER A SHAPED PORT VARYING THE EXPOSED AREA IN SOME PRESCRIBED FASHION. TWO OF THESE AREAS ARE USED TO FORM AN AREA RATIO WHICH IS A UNIQUE FUNCTION OF THE PRESSURE RATIO OF CONCERN. THE THIRD GENERATES AN OUTPUT SIGNAL WHICH IS A FUNCTION OF THE SHAFT POSITION, WHICH, IN TURN, YIELDS AN OUTPUT INDICATIVE OF THE SENSED PRESSURE RATIO.

摘要： A PUSH-PULL FLUERIC LAG-LEAD CIRCUIT IS DISCLOSED WHICH INCORPORATES A FLUID AMPLIFIER IN IS FORWARD LOOP AND A PAIR OF POSITIVE FEEDBACK PATHS FROM THE OUTPUT OF THE FLUID AMPLIFIER TO THE CONTROL PORT. THE POSITIVE FEEDBACK PATH COMPRISES A PAIR OF FLOW RESISTANCES IN SERIES WITH EACH OTHER AND WITH A VOLUME WHICH PROVIDES A CAPACITANCE TO GROUND.
