    摘要： A fluidic oscillator includes a chamber having a common inflow and outflow opening into which a jet is issued in a generally radial direction. After impinging upon the far chamber wall the jet is redirected to form a vortex on each side of the incoming jet. The vortices alternate in strength and position to direct outflow through the common opening along one side and then the other of the inflowing jet. A spray-forming output chamber is arranged to receive the pulsating outflows from the aforementioned or other fluid oscillator and establish an output vortex which is thereby alternately spun in opposite directions. An outlet opening from the output chamber issues fluid in a sweeping spray pattern determined by the vectorial sum of a first vector, tangential to the output vortex and a function of the spin velocity, and a second vector, directed radially from the vortex and determined by the static pressure in the chamber. By increasing or decreasing the static pressure, or by increasing or decreasing the vortex spin velocity, the angle subtended by the sweeping spray can be controlled over an unusually large range. By properly configuring the oscillator and/or output chamber, concentrations and distribution of fluid in the spray pattern can be readily controlled.

    摘要： A fluidic steering control system having at least two propelling means, one for each side of the vehicle, a separate variable speed transmission for driving each of the propelling means, a separate fluidic circuit for driving each of the transmission means, a common steering transducer for controlling the relative outputs of the amplifying means, and feedback means for providing a feedback dependent upon the relative speeds of the transmissions.

    摘要： In a pneumatic control system having pneumatic logic elements for signal processing to perform a control function, the elements are divided in two groups. The first group require an energy supply to change their states but do not require the energy supply to maintain a stable state. The second group require energy both to change state and to maintain a set state. The second group are connected directly to a pneumatic energy source while the first group are connected through an on-off control means so that energy is applied thereto during signal processing and is removed in a stable state of the system so as to avoid unnecessary energy consumption in the first group. The control means may be actuated to allow energy supply to the first group by a device responsive to incoming signals for processing by the system.

    摘要： A constant-bias differential fluidic signal generator. A zerobias differential fluidic signal is summed with a constant but adjustable bias signal. The zero-bias differential signal is generated by two signals that increase and decrease proportionately and simultaneously as a function of a control pressure. Such signals can be generated with a fluidic aspirator that creates a vacuum signal in proportion to an applied pressure signal. If the transfer characteristic of such an aspirator is linear with unity gain, the bias of the differential signal generated thereby would be zero. The two signals generated by the aspirator are combined with a constant-bias signal through a pair of passive summing junctions. This provides not only a constant bias level but one which is independently adjustable by means of the constant-bias signal level, thereby rendering the device very valuable in the testing of fluidic components and systems.

    摘要： The invention relates to a fluid pressure-ratio switching circuit which provides an output only when one of a pair of independent control signals is greater than the other. Switching is effected in a bistable fluidic device, one or both of the outputs of which are used to provide control signals for two subsequent stages of amplification. Amplification is effected by a pair of fluidic proportional amplifier devices, the arrangement being that the circuit output is taken from the vent port of the final amplifier device.
