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.

Disclosed a regulator for clutch actuator. The regulator for clutch actuator includes a housing having a cylindrical damping space inside, a first fluid path interconnecting the damping space and a master cylinder, and a second fluid path interconnecting the damping space and a an operating cylinder. The regulator further includes a flexible valve member contained in the damping space for reducing vibrations. The flexible valve member comprises a first inflow guiding portion configured to receive and guide fluid from the first fluid path. The first inflow guiding portion has a plurality of through holes such that elastic deformation of the first inflow guiding portion reduces vibration when fluid flow into the cylindrical damping space from the master cylinder.

An aspect of the present disclosure includes a multi-stage compressor having a low pressure compressor stage and a high pressure compressor stage operable for compressing a working fluid. An integrated device including a heat exchanger directly connected to a combination unit is operable for reducing pressure pulsations, cooling and separating moisture in a first compressed flow stream and a second compressed flow stream discharged from the low pressure stage and the high pressure stage respectively. A first pressure pulsation dampener, a first moisture separator, a second pressure pulsation dampener and a second moisture separator are integrally formed within the combination unit.

A scale-dampening or scale-inhibiting device is at a radial restriction in a pipeline. A helical flow guide is arranged in a pipeline portion upstream of the restriction. The flow guide projects radially inwards from a pipe wall and has a longitudinal direction slanted relative to the center axis of the pipeline. A method is for dampening or inhibiting scaling in a dead zone of a fluid flow downstream of a restriction in a pipeline.

An in-line ultrasonic attenuator (10) of this disclosure includes a longitudinally extending pipe (20) having a first and second end (21, 31), and a constant inside diameter extending an entire distance between the first and second ends. Instead of plates, the attenuator includes at least one helical baffle (23 or 33), or a first and a second helical baffle (23, 33) arranged in series with one another, coaxial to the longitudinal center line of the longitudinally extending pipe. The first helical baffle has a first twist rotation and the second helical baffle has a second twist rotation opposite that of the first twist, each twist rotation being at least 180. The pipe ID can be the same as that connected to the ultrasonic gas flow meter. No elbows are required at the front or back end of a measurement skid of which the attenuator is a part.

A fluid governing system including a fluid inlet and fluid inlet port coupleable to an upstream pipe segment; a fluid outlet and a fluid outlet port coupleable to a downstream pipe segment; a flow unit; a metering inlet path in flow communication with the fluid inlet; a metering outlet path in flow communication with the fluid outlet, the metering inlet path is in flow communication with the metering outlet path through the flow unit which is articulable between the metering inlet path and the metering outlet path; a pressure responsive sealing diaphragm for selective sealing a metering inlet port; an inlet chamber disposed at a face of the sealing diaphragm, the inlet chamber in flow communication with the fluid inlet; a control chamber disposed at an opposite face of the sealing diaphragm; and a control fluid duct extending between the inlet chamber and the control chamber.

A flow conditioning device for incrementally stepping down pressure within a piping system is presented. The invention includes an outer annular housing, a center element, and at least one intermediate annular element. The outer annular housing includes an inlet end attachable to an inlet pipe and an outlet end attachable to an outlet pipe. The outer annular housing and the intermediate annular element(s) are concentrically disposed about the center element. The intermediate annular element(s) separates an axial flow within the outer annular housing into at least two axial flow paths. Each axial flow path includes at least two annular extensions that alternately and locally direct the axial flow radially outward and inward or radially inward and outward thereby inducing a pressure loss or a pressure gradient within the axial flow. The pressure within the axial flow paths is lower than the pressure at the inlet end and greater than the vapor pressure for the axial flow. The invention minimizes fluidic instabilities, pressure pulses, vortex formation and shedding, and/or cavitation during pressure step down to yield a stabilized flow within a piping system.

A hydraulic component, in particular of a hydraulic braking system, includes a conduit section through which brake fluid flows. The conduit section has at least one reflection surface that is impinged by the brake fluid.

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.
