    • A fluidic set point amplifier (10) provides an output signal which is strongly linear with respect to pressure (16) of fluid supply, free of hysteresis, and has a zero crossing (60) (set point) at a determined value of supply pressure. The set point amplifier may be character­ized in that it includes a housing (10); said housing (10) defining an inlet port (16) communicating with a source of pressurized elastic fluid, an outlet port (20) communi­cating with a source of reference pressure, and a flow path (28) extending from said inlet port (16) to said outlet port (20) for communicating a flow of said elastic fluid there­between; said flow path (28) defining a convergent-divergent (de Laval) nozzle (36, 38, 40) having a convergent section (36) leading from said inlet port to a throat section (38) of minimum cross sectional flow area, and a divergent section (40) extending downstream of said throat section (38) to said outlet port (20); and an output signal port (42) communicating with said throat section (38) for pro­viding a fluid pressure level output signal in response to a flow of elastic fluid in said flow path, whereby in response to a progressively increasing pressure differential between said inlet port and said outlet port said fluid pressure level output signal includes a progressively decreasing sub-reference pressure level followed by a progressively increasing sub-reference pressure level increasing to said reference pressure, and a progressively increasing supra-­reference pressure level; which increasing sub-reference and supra-reference pressure levels are substantially linearly related to said increasing pressure differential between said inlet port and said outlet port and are substantially free of hysteresis. Uses of the set point amplifier include an all-fluidic pressure regulator, and a turbine engine fuel control having only a single moving part.

    • A delay valve (10) has a body defining an enclosure (14), with a separating plate (16) and diaphragm operator (22) therein to define an input (18), output (20) and third (24) chamber. The input (18) and output (20) chambers are adjacent, and separated by the separating plate (16). This plate (16) defines an aperture (30), an umbrella valve opening (26) and a port (28), all of which communicate between the input (18) and output (20) chambers. A stem (40) and seal (42) arrangement is affixed to and operable by the diaphragm operator (22) against the bias force of a spring (44), to seal communication through the port (28) at and above a pressure differential between the output (20) and third (24) chambers. As the input (18) chamber vacuum decreases, the output (20) chamber vacuum level likewise decays through the aperture (30) at a relatively slow rate. When the pressure differential between the output (20) and third (24) chambers is inadequate to overcome the bias force of the spring (44), the port (28) opens and thus produces equilibrium between the input (18) and output (20) chambers. This delay valve (10) thus rapidly returns to an equilibrium position and is again ready to commence controlling without awaiting a slow decay return to equilibrium.

    • Fluidic computation is simplified in a system wherein one of plural input parameters is a fluid flow which is to be multiplied by the sum of the other parameters. The primary computation element is a parallel flow sensor in which a fluid sensing jet is issued from within and parallel to the fluid flow and is received as a linear function of the fluid flow. The effects of other input parameters are included by utilizing each to vary the supply pressure for the sensing jet to thereby sum the effects of these parameters and multiply the sum by the fluid flow. In a preferred embodiment, the computation element is utilized in a fluidic fuel injection control for an internal combustion engine wherein the fluid flow is air flow through the intake manifold and the other input parameters include fuel-to-air ratio, inlet air pressure, inlet temperature and engine temperature. The resulting output signal represents the required fuel flow which is then modified by fluidic circuitry to deliver the proper quantity of fuel per cylinder stroke.
    • 在其中多个输入参数中的一个是要乘以其他参数的和的流体流的系统中,流体计算被简化。 主要计算元件是平行流量传感器,其中流体感测射流从流体流内并且平行于其发出并被接收为流体流动的线性函数。 通过利用其他输入参数来影响感测射流的供应压力,从而总结这些参数的影响,并将和乘以流体流量。 在优选实施例中,计算元件用于内燃机的流体燃料喷射控制,其中流体流动是空气流过进气歧管,而其它输入参数包括燃料与空气之比,进气压力,入口 温度和发动机温度。 所得到的输出信号表示所需的燃料流量,然后由流体回路改变以便每个气缸行程输送适量的燃料。

    • A fluidic fuel injection system is illustrated and described having fluidic means to modulate the duration of the normally generated injection pulse. The pulse extender receives the normally generated injection pulse and applied that pulse through gating means to the fuel injection controlling device. The pulse extender also receives a signal indicative of an engine operating parameter such as for instance, an engine temperature, and stores a signal which is a function of the duration of the normally generated injection controlling pulse and the engine variable. Following termination of the normally provided injection controlling pulse, the stored signal is then communicated to the fuel injection controlling devices to provide for prolongation, in a predetermined controlled manner, of delivery of fuel.
