摘要： Fluidic devices wherein the fluid stream or streams acting therein are always in the laminar state. The important elements of each fluidic device, which include one or more supply passageways, one or more receiver passageways, vents, a cavity and possibly one or more control passageways, are of a configuration and location such that fluid flowing through each supply passageway forms a laminar fluid stream which is capable of being received by one or more of the receiver passageways in a laminar state. The Reynolds number of the fluid forming the laminar fluid stream is preferably within the range of 200-1,500. The subject invention is applicable to a wide variety of fluidic devices including proportional and digital amplifiers, OR and AND gates, and rate sensors wherein the signal-to-noise ratio is substantially lower than that of conventional turbulent flow fluidic devices.

摘要： A fluidic control system for regulating the temperature of fluid for cooling a garment having a fluid signal amplifier, a vortex value and an impact modulator. Cold fluid is throttled by the vortex valve and the output from the vortex valve is passed to one input port of the impact modulator. Warm water is fed to a second input port of the impact modulator and the stream of cold fluid impacts with the stream of warm fluid and the resulting mixture flows from the output port of the impact modulator to tubing in the garment.

摘要： TECHNIQUES ARE DISCLOSED WHEREIN SYMMETRY OF OPERATION, GAIN AND/OR FREQUENCY RESPONSE CHARACTERISTICS OF FLUIDIC AMPLIFIERS MAY BE SELECTIVELY VARIED. IN ONE TECHNIQUE AN AMPLIFIER VENT PASSAGE IS PROVIDED WITH ONE OR MORE INSERTS WHICH CHANGE IN SIZE AND SHAPE IN RESPONSE TO TEMPERATURE AND/OR QUALITATIVE COMPOSITION OF THE WORKING FLUID, THE LATTER TWO PARAMETERS BEING SELECTIVELY VARIABLE TO CHANGE THE FLOW IMPEDANCE OF THE VENT PASSAGE. ANOTHER TECHNIQUE EMPLOYS A SIMILAR INSET IN A FLUIDIC CAPACITOR CONNECTED TO THE AMPLIFIER OUTPUT PASSAGE, WHEREBY THE CAPACITY OF THE OUTPUT PASSAGE, AND HENCE THE FREQUENCY RESPONSE OF THE AMPLIFIER, IS SELECTIVELY VARIABLE WITH EITHER WORKING FLUID TEMPERATURE OR WORKING FLUID QUALITATIVE COMPOSITION. IN STILL ANOTHER TECHNIQUE THE REYNOLDS NUMBER OF A POWER STREAM IN A TURBULENCE AMPLIFIER IS SELECTIVELY VARIED BY VARYING FLUID TEMPERATURE, PRESSURE AND/OR QUALITATIVE COMPOSITION, WHEREBY TO VARY THE SENSITIVITY OF THE POWER STREAM TO TURBULENCE IN RESPONSE TO DIFFERENT INPUT SIGNAL FREQUENCIES. IN ANOTHER TECHNIQUE FLUIDIC CAPACITORS, CONNECTED TO THE INPUT AND/OR OUTPUT PASSAGES OF A FLUIDIC AMPLIFIER, ARE SELECTIVELY VARIED BY INTRODUCING VARIABLE QUANTITIES OF CONTROL FLUID INTO THE CAPACITORS, THE VARIABLE CAPACITY PROVIDES CORRESPONDING VARIABLE AMPLIFIER FREQUENCY RESPONSE CHARACTERISTICS. IN ANOTHER TECHNIQUE, THE POWER STREAM PRESSURE IN A FLUIDIC AMPLIFIER IS AUTOMATICALLY VERIED TO MAINTAIN THE MINIMUM POWER STREAM PRESSURE NECESSARY TO PROVIDE A LINEAR AMPLIFIER GAIN CHARACTERISTICS FOR VARYING INPUT SIGNAL RANGES.

摘要： A passive fluidic reference circuit includes at least a first fluid flow restrictor connected between a pneumatic supply pressure source Ps and the circuit output Pr, and second restrictor connected between the circuit output and a vent. The first and second restrictors are of types which obtain pressure drops thereacross varying with absolute temperature T as the functions Ps- Pr K1Ty omega and Pr K2Tz, respectively. Operation of the passive circuit and a temperature-sensitive fluidic circuit whose output pressure signal Po varies with temperature as (Po/Ps) (Ka/Tx) is made essentially insensitive to temperature changes for the conditions x y- z and (K2/K1) Ka which establishes a reference operating point Po Pr.

摘要： The gain of a fluidic proportional integrator circuit is alternately reduced to zero to obtain a fluidic reset integrator having no moving mechanical parts. A rapid reduction to zero gain is achieved by alternately switching the output of a digital fluid amplifier from the power fluid inlet of a proportional fluid amplifier in the integrator circuit in accordance with the pressure magnitude at the output of the integrator circuit.

摘要： A FLUIDIC AMPLIFIER CIRCUIT RESPONDS TO A VARIABLE PRESSURE INPUT SIGNAL AT A RELATIVELY LOW AVERAGE PRESSURE LEVEL TO PROVIDE AN AMPLIFIED VERSION OF THE PRESSURE INPUT SIGNAL AT A SUBSTANTIALLY HIGHER AVERAGE PRESSURE LEVEL. THE CIRCUIT COMPRISES A PLURALITY OF CASCADED FLUIDIC AMPLIFIER STAGES, THE INTERACTION REGIONS OF SUCCESSIVE STAGES BEING MAINTAINED AT RESPECTIVE SUCCESSIVELY INCREASING PRESSURES BY RESTRICTING VENT FLOW FROM EACH STAGE AS REQUIRED. THE INTERACTION REGION PRESSURE IN ANY STAGE MUST NOT BE SO GREAT RELATIVE TO THE AVERAGE PRESSURE LEVEL OF THE INPUT SIGNAL FOR THAT STAGE AS TO PREVENT THE INPUT SIGNAL FROM FLOWING INTO THAT STATE, NOR SO SMALL RELATIVE TO THE POWER STREAM PRESSURE AS TO CAUSE EXCESSIVE DIFFUSION OF THE POWER STREAM UPON ENTERING THE INTERACTION REGION.

摘要： Variable function generation techniques are disclosed for fluidic systems. One technique employs a fluidic amplifier which is constructed to provide an output signal as a variable function of an input signal in accordance with selectively variable proportioning of the input signal among the amplifier input ports. Alternatively, the input signal is variably proportioned between plural amplifiers having different gain characteristics, the output signals of each amplifier being combined to provide a common signal. A still further alternative comprises amplification of a differential pressure signal in a proportional three-output passage fluidic amplifier, the three output signals from the amplifier being selectively paired to provide various functions of the input signal, the various functions in turn being selectively gated to provide an output signal comprising various combinations of the functions.

摘要： A flueric amplifier with two control ports for each control channel. Each control channel is split to operate both ports. The control flow is split and applied to the power jet through the two separate control ports. This separate application is called distributed control and results in greater flow recovery and pressure recovery as well as improved switching time. One of the control ports comprises an entrainment control port for introducing positive pressure control fluid to the attachment bubble existing along the attachment wall, and the other one of the control ports constitutes a momentum exchange control port for creating a momentum impact force on the power stream.
