摘要： Leakage components are described herein. The leakage component includes a first tubing housing and a plurality of leakage ports. The first tubular housing defines a first flow path between a first end portion and a second end portion. The plurality of leakage ports are formed in the first housing and in fluid communication with the first flow path. The fluid flow through the plurality of leakage ports is configured to entrain ambient air into the fluid flow exiting the plurality of leakage ports to decelerate the fluid flow.

摘要： Apparatus, systems and methods for implementing flow cages and flow cage assemblies in association with high pressure fluid flows and fluid valves are provided. Flow cages and flow assemblies are provided to dissipate the energy of a fluid flow, such as by reducing fluid flow pressure and/or fluid flow velocity. In some embodiments the dissipation of the fluid flow energy is adapted to reduce erosion, such as from high-pressure jet flows, to reduce cavitation, such as by controllably increasing the flow area, and/or to reduce valve noise associated with pressure surge.

摘要： A laminar flow tool is for channeling water, air or other fluids through a down drill pipe or tubing for pressurization of other tools or other purposes. The tool provides a flow divider having an 180 degree twist separating a driven fluid chamber from a buffer fluid pocket. Fluid in the tool is calmed as it travels and loses some of the spin (“turbulence”) inherent in the water or other fluid. A buffer pocket on one side absorbs shocks and stabilizes the driven side. Ports in the buffer side help equalize pressure.

摘要： A co-axial stack of annular disks, each of which is preferably made of a sheet metal so thin as to be individually flexible, is held under axial compression to define an essentially rigid column. Each disk, on at least one surface thereof, is integrally formed with a plurality of radially extending depressions, preferably of non-circular cross-section, whose sidewalls diverge radially outwardly away from one another, each such depression defining a diffuser passage with a surface of an adjacent disk. The disks are formed with substantially identical patterns of depressions and the plurality of disks are substantially identically angularly oriented with respect to each other so that the land areas between depressions are directly superimposed on each other to sustain the axial compression of the stack without deformation of the individual thin disks. The compressed stack provides a very high density of inlet and outlet orifices on the inner and outer walls thereof whose interconnecting passageways are opened or closed by axial movement of a valve member through the central passage defined by the stack. The gradient of increase in cross-sectional area of the diffuser passages from inlet to outlet is calculated to maintain a substantially constant velocity of the gas flow therethrough, with a gradually increasing specific volume gradient from inlet to outlet.

摘要： Disclosed is a device for reducing flow noise. In order to achieve a low flow noise, the device includes inlet apertures for receiving a fluid flow, chambers into which one or more inlet apertures open up, a cross-sectional area of a single chamber being larger than a combined flow cross-sectional area of the inlet apertures opening up thereto, and chamber-specific outlet apertures for forwarding the fluid flow from the chamber, a flow cross-sectional area of each outlet aperture being smaller than the cross-sectional area of the chamber, and the combined flow cross-sectional area of all outlet apertures of the single chamber being larger than the combined flow cross-sectional area of the inlet apertures opening up into said chamber.
