Abstract: Provision of flow control arrangements which can be switched from high flow restriction to low flow restriction or vice versa are desirable. It is known to use switched vortex valves comprising a vortex chamber having a diverter portion which jets a through flow into either radial presentation to an outlet or tangential presentation with differential flow restrictions. Typically deflection is through cross flows presented from control ports as determined by mechanically actuated and controlled valves. Sensors are required to determine pressure differentials in order to actuate these moving part valves. By providing association between the control ports and an outlet path along with appropriate configuration and sizing of the flow regulators switching states can be provided through the cross flows presented via the flow regulators between the high and low through flow restriction. The flow regulators generally comprise orifice restrictors, diffusers/venturi arrangements or vortex throttles.

Abstract: For achieving a shut-off function, a mainstream communicates with a control stream into which an outlet for the mainstream opens laterally. By reciprocating the control stream back and forth across the outlet, for example by alternate pressurisation of reservoirs to which the control stream is connected at its ends, access of the mainstream to the outlet is inhibited. When the reciprocation is discontinued full flow of the mainstream to or through the outlet can take place.

Abstract: A fuel injector including a combustion air flow conduit, a fuel inlet and, swirlers to mix the air and fuel flowing therethrough, additionally comprising fluidic control diverters including at least one control port, such that flow of control air through said control port allows variation in the degree of flow resistance to which combustion air is subjected. For example, control air flowing through the control port may impart swirl to the combustion air flow from the inlet, thereby subjecting the combustion air flow to increased resistance. Alternatively a fluidic diverter may selectively divert the main flow to either the first or second sub-conduits, each sub-conduit subjecting combustion air to different degrees of flow resistance.

Abstract: A system for separating a liquid and a gas including a separation vessel (30) with an inlet (28) for a gas/liquid mixture. Outlets (40, 42) for the fluids are disposed at different heights in the vessel. The outlets are controlled by turn-up vortex amplifiers (fluidic valves TuVAs) that include a supply port (40, 42), a control port (36, 38) and an outlet port (48, 50). The control port is supplied from the vessel at an intermediate level between the outlets, so that a change of flow in the control port alters resistence to flow through the valve.

Abstract: A fluidic flow control device includes at least three terminals with two of the terminals being connected to input nozzles opposing each other in axial alignment. An interspace is provided adjacent the point of intersection of the two streams from the nozzles and a radial diffuser is provided encircling the interspace. The third terminal communicates with the radial diffuser. The variable relationship between the flows produced at the nozzles is effective to control the flow at the third terminal. The diffuser is formed by planar faces separated by a constant width gap. The gap opens into an annular plenum to which the third terminal is connected. The entry area to the radial diffuser is sized to be substantially equal to the sum of the areas of the nozzle throats. In one embodiment, a mixer region may be provided between the diffuser and at least one of the nozzles. A fourth terminal acting as a vent may communicate with the mixer region. If desired, a second radial diffuser may be provided and one nozzle throat may be larger than the other. A partition may be provided in the diffuser.
