A valve can include one or more ribs in an inlet flow path, an outlet flow path or another flow path and a rib can be coupled between two or more portions of a valve.

An aircraft gas transport system including a high pressure gas supply line having a supply valve, and an equilibrium gas line joined at junctions with the high pressure gas supply line upstream and downstream from the supply valve, and in flow communication with the high pressure gas supply line, the equilibrium gas line having an equilibrium valve and a flow restrictor, the equilibrium valve having an exit orifice and the flow restrictor being offset from the exit orifice of the equilibrium valve.

A fluid distribution apparatus and a fluid distribution module with choke are provided. The fluid distribution apparatus includes a first fluid conveying pipe, a second fluid conveying pipe, multiple fluid manifolds located between the first fluid conveying pipe and the second fluid conveying pipe and connected with the first fluid conveying pipe and the second fluid conveying pipe, an inlet disposed on a side of the first fluid conveying pipe and between both ends of the first fluid conveying pipe; and an outlet disposed on a side of the second fluid conveying pipe and set corresponding to a position where the inlet is set. The fluid is supplied from the inlet to the first fluid conveying pipe, and the fluid is conveyed to the fluid manifolds along the first fluid conveying pipe, and flows into the second fluid conveying pipe through the fluid manifolds and flows out from the outlet.

A system provides regulated delivery of a high-pressure gas. A first flow path, coupled to a high-pressure gas source, is in fluid communication with a chamber. A flow restrictor, disposed in the first flow path, slows the gas traveling along the first flow path to the chamber. A second flow path, coupled to the high-pressure gas source, is in fluid communication with the chamber. A third flow path connects the chamber to a pressure regulator. A valve, disposed in the second flow path, seals the second flow path when gas pressure at the source exceeds gas pressure in the chamber. The valve opens the second flow path when the gas pressure at the source is balanced with the gas pressure in the chamber allowing the high-pressure gas to flow to the regulator via the third flow path.

A pressure type flow rate control apparatus is provided wherein flow rate of fluid passing through an orifice is computed as Qc=KP1 (where K is a proportionality constant) or as Qc=KP2.sup.m (P1-P2).sup.n (where K is a proportionality constant, m and n constants) by using orifice upstream side pressure P1 and/or orifice downstream side pressure P2. A fluid passage between the downstream side of a control valve and a fluid supply pipe of the pressure type flow rate control apparatus comprises at least 2 fluid passages in parallel, and orifices having different flow rate characteristics are provided for each of these fluid passages, wherein fluid in a small flow quantity area flows to one orifice for flow control of fluid in the small flow quantity area, while fluid in a large flow quantity area flows to the other orifice for flow control of fluid in the large flow quantity area.

A high purity water delivery system has a reservoir (40) of purified water. A distribution line (42) extends downstream from an outlet (44) of the reservoir to a return (46) of the reservoir. A plurality of delivery stations each include an outlet (54) and a diverter (102; 102; 102; 102). The diverter has an upstream inlet port (104) along the distribution line and a downstream outlet port (106) along the distribution line. The diverter has a supply port (108) downstream of the inlet port and a return port (110) downstream of the supply port. The diverter has a flow restriction (112; 112; 216) between the supply port and the return port. Each delivery station includes a flow control valve (56) between the outlet on the one hand and the supply port and return port on the other hand.

There is provided a cleaning apparatus for unclogging an irrigation emitter inlet filter by dislodging or crushing or breaking a trapped solids. In some embodiments, a ram pushes the trapped solids out of a fluid inlet of the emitter. In other embodiment, a constriction provided for retaining a particle has a changeable interior cross section. By changing the cross section of the constriction, the constriction is unclogged. In alternative embodiments the filtration member may include two rigid members moving in relation one to the other or the filtration member may be elastic. In further alternate embodiments the cleaning may be activated automatically or manually.
