    摘要： The circuit includes a high gain fluidic amplifier device in a forward circuit portion and a vortex fluidic device in a negative feedback circuit portion connected around the forward circuit. The vortex device may be a passive component utilizing only a control fluid input from the amplifier output, or may be an active component utilizing both the control (tangential) fluid input and a power fluid (radial) input supplied from a source of constant pressurized fluid.

    摘要： A fuel-pumping system for a gas turbine engine includes a jet pump in the fuel tank, a boost pump, a pressure pump, and a fuel control to control the fuel supply from the pressure pump to the engine. The jet pump is energized by fuel diverted from the outlet of the pressure pump through a static vortex-type flowresisting device having a pressure drop proportional to flow raised to a power greater than two. This device reduces the amount of increase in fuel returned to the jet pump which would otherwise occur under high-pressure discharge conditions of the pressure pump.

    摘要： SPARK TIMING IN A SPARK IGNITION ENGINE IS CONTROLLED TO PROVIDE MAXIMUM ENGINE TORQUE BY UTILIZING A FLUIDIC LOGIC CIRCUIT IN COMBINATION WITH AN ACTUATOR FOR SELECTIVELY ADVANCING AND RETARDING SPARK TIMING IN RESPONSE TO FLUID SIGNALS AND A SENSOR FOR DETECTING INCREASING AND DECREASING ENGINE TORQUE. AT ANY GIVEN ENGINE SPEED THE LOGIC CIRCUIT SEEKS THE ACTUATOR DIRECTION WHICH PRODUCES INCREASING TORQUE BY PROVIDING SIGNALS WHICH MOVE THE ACTUATOR ALTERNATELY TO ADVANCE AND RETARD THE SPARK TIMING AND BY SENSING THE RESULTING INCREASE OR DECREASE IN ENGINE TORQUE. AN INCREASE IN ENGINE TORQUE CAUSES THE CIRCUIT TO CONTINUE TO MOVE THE SPARKTIMING ACTUATOR IN THE SAME DIRECTION, A DECREASE IN ENGINE TORQUE RESULTS IN A REVERSAL OF THE ACTUATOR DIRECTION. THE SPARK TIMING IS THEREFORE ADJUSTED UNTIL THE MAXIMUM TORQUE IS REALIZED AND THE CONTROL SYSTEM THEN ENTERS A LOW-AMPLITUDE MODE OF OSCILLATION ABOUT THE MAXIMUM-TORQUEPRODUCING ACTUATOR POSITION UNTIL A TORQUE VARIATION IS ONCE AGAIN SENSED.

    摘要： A vortex flow control device having a chamber with a main stream input flowing radially inward during one mode of operation and flowing in a logarithmic spiral path during a second mode of operation for creating a back pressure for a metering element which is inversely proportional to the flow rate of the fluid issuing from said metering element.
