摘要： The present invention is directed to an improved fluid diode using topology optimization with Finite Element Method (FEM). Topology optimization as a flexible optimization method has been extended to the fluid field. For given boundary conditions and constraints, it distributes a specific amount of pores (or remove materials to get channel) in the design domain to minimize/maximize an objective function. In this design, inlet and outlet ports are aligned and inflow and outflow are in the same direction. The present invention features an intricate network of fluid channels having optimized fluid connectivity and shapes, which significantly improves the diodicity of fluidic passive valves.

摘要： A fluidic pulse generator system includes two fluidic diverter valves that are both controlled by a single fluidic pilot valve. The fluidic pilot valve and the two fluidic diverter valves are each adapted to receive a flow of pressurized fluid. The flow of pressurized fluid through the fluidic pilot valve is controlled in response to pressurized fluid flow through a control valve. In turn, the flow of pressurized fluid through the two fluidic diverters valves is simultaneously controlled in response to the flow of pressurized fluid through the fluidic pilot valve.

摘要： The fluid amplifier may be considered as including a device in which is formed the initial fluid flow pattern and which constitutes the main power input, the control inputs and the receiver, or output. At chosen points second fluid jets are admitted in chosen directions and under chosen flow rate and pressures to modify and control the main jet in a chosen or logical way. A third jet may be interposed from an opposite direction for further modification of the main jet. The main jet may be modified in such a way as to produce an output wave having a frequency that is twice the input frequency. Using two amplifier elements in said series produces an output four times the frequency of the input, N amplifiers in series producing 2N times the frequency of the input.

摘要： Techniques are disclosed whereby fluid output signals are provided as selectively variable functions of fluid input signals. One technique employs a fluidic amplifier wherein a fluid output signal varies as a function of the deflection of the amplifier power stream and of the transverse velocity profile of the power stream, the function being rendered variable by providing a fluid stream flowing adjacent to and in a direction opposite to the power stream whereby to selectively modify the power stream velocity profile. Alternatively, a substantially wedge-shaped wall is disposed adjacent the undeflected power stream with the apex of the wedge pointing generally transversely of the direction of the power stream. A command stream of fluid is directed so as to deflect the power stream against the upstream side of the wedge-shaped wall whereby the power stream bounces off the wall at an angle dependent upon the point at which the power stream impacts against the wall. A still further alternative comprises a fluidic circuit in which a variable pressure gain command signal is converted to a correspondingly variable-frequency oscillatory signal which is amplitude modulated by a fluid input signal. The amplitude-modulated signal is then passed through a filter network having a variable amplitude versus frequency characteristic in the range of the oscillatory signal frequency. The amplitude modulation envelope is then recovered by a detector and filter combination to provide an output signal at an amplitude which differs from the input signal amplitude as a function of the gain versus frequency characteristic of the filter. Still other alternatives are disclosed wherein variable pressure input signals are converted to correspondingly variable frequency oscillatory signals, the frequencies of which are varied in accordance with desired gain changes for the input signal and then reconverted to pressure signals at correspondingly varied pressure levels.
