A resonator assembly includes an outer tube that extends from an inlet to an outlet. The outer tube has at least two chambers formed along a length of the outer tube. An inner tube extends from an inlet to an outlet. The inner tube includes a plurality of perforations formed about the circumference of the inner tube. The inner tube is positioned with the outer tube. The inner and outer tubes frictionally engage upon assembly sealing the at least two chambers relative to each other.

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.

Flow restrictor assemblies including a monolithic flow restrictor and methods for manufacturing the same are provided. The monolithic flow restrictor is configured for disposing in a fluid passage of a housing body. The monolithic flow restrictor comprises a first end and a second end, a first screen at the first end and a second screen at the second end, and a series of cross-sectional portions between the first screen and the second screen. Each cross-sectional portion has a plurality of slots formed in a radially outer surface thereof for connecting a series of restricting orifices formed in the monolithic flow restrictor for tortuously conducting a fluid through the series of cross-sectional portions.

A choke for a flow line having an inner diameter has a body with an upstream end, a downstream end, and a sidewall that extends between the upstream end and the downstream end. The sidewall has a diameter that is sized to fit within the inner diameter of the flow line. A fluid impact face is provided at the upstream end of the body. The fluid impact face has a recessed central portion. One or more passages provide fluid communication between the downstream end and the sidewall of the body.

In one form, a compressor system includes a compressor, and an annular ring disposed downstream of the compressor and structured to reduce pressure fluctuations in the pressurized air discharged by the compressor. The annular ring may include an internal passage for conducting the pressurized air. The annular ring may include at least one resonator in fluid communication with the internal passage. Further embodiments, forms, features, aspects, benefits, and advantages of the present application will become apparent from the description and figures provided herewith.
