An apparatus comprises an input chamber being configured for accepting a flow of material. An output chamber is configured for flowing the material along a first pathway and a second pathway. A diverter member is disposed within the input chamber. The diverter member comprises a half wing shape pivotally joined at a juncture of the input chamber and the output chamber. The diverter member is operable to be positioned at a first position for diverting the flow to the first pathway and to be positioned at a second position for diverting the flow to the second pathway. A lever mechanism is configured to be operable for moving the diverter member between the first position and the second position in which the flow is uninterrupted.

A fuel delivery system includes a connection assembly that reliably connects a high pressure fuel supply line to an inlet of a fuel rail. The connection assembly includes a fitting that decouples the retention function of the connection from the sealing function of the connection. The fitting is hollow and has a spherical leading end that is compressed against an inner conical surface of the fuel rail inlet to an extent that fuel rail material is displaced by the spherical leading end and a fluid-tight first seal is realized between the fitting and the conical surface of the fuel rail inlet. A weld is provided at a location spaced apart from the seal, the weld joining the fitting to the fuel rail inlet and retaining the fitting within the inlet in a compressed state, whereby the first seal is maintained.

The invention relates to a fluid transport pipe. A first unit channel in which a channel cross-sectional area continuously decreases toward a downstream side and a second unit channel in which a channel cross-sectional area continuously increases toward the downstream side are alternately combined. A ratio A (=L/{[Smax].sup.1/2-[Smin].sup.1/2}) is set within a range in which a drag reduction rate R.sub.D becomes a positive value. The fluid transport pipe includes: a first opening formed in a channel wall of the first unit channel; a second opening formed in a channel wall of the second unit channel; and a bypass channel that allows by-passing of a flow from the first unit channel to the second unit channel through the openings.

Disclosed is a flow control valve 100. The flow control valve 100 comprises a cylindrical body 20, a piston 40, at least one fluid seal 60, a handle 60 and a nut 90. The flow control valve 100 is connected between an inlet and an outlet of a pipe to control flow of liquid/gases passing there through even at high temperature and pressure. The flow control valve 100 provides good force to the liquid/gas passing there through and provides an equal distribution of the flow at the outlet without resulting in pressure drop.

A fluid flow modifier device comprising: an inlet portion for receiving a flow of fluid; an outlet portion for outputting the flow of fluid; and a flow modifier portion disposed between the inlet portion and the outlet portion, the flow modifier portion comprising an outer portion comprising a closed cross-section to the flow of fluid and an inner porous portion configured such that at least a portion of the flow received in the inlet portion must pass through the inner porous portion to reach the fluid outlet. The fluid flow modifier device is ideally used to transition fluid flow between an fluid supply line and a fluid treatment zone—for example, a pressure water supply line and an ultraviolet radiation treatment device (e.g., drinking water treatment device).

A device for dampening pressure pulsations in a gas flow including a vessel with an inlet and an outlet, the vessel defines an internal volume for the transit of the gas; a choke tube in fluid communication with the vessel and placed completely outside the internal volume of the vessel.

A branching structure according to an embodiment includes an introduction path part and branch path parts. The introduction path part includes an introduction path extending in a first direction. The branch path part includes parallel branch paths. The branch paths each include an upstream section extending in a second direction intersecting with the first direction and a downstream section extending in the first direction. The branch paths continue into the introduction path or upstream branch paths. In each of the branch path parts, the numbers of the upstream sections up to the branch paths are the same. The branch path parts more downstream have a larger number of downstream sections.
