    摘要： A fuel injector (2) including a combustion air flow conduit, a fuel inlet (2.4) and means to mix the air and fuel flowing therethrough (2.2, 2.3, 2.6), additionally comprising fluidic control means (2.7) including at least one control port (3.4, 3.5, 3.6, 3.7), 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 (2.7) may selectively divert the main flow to either the first or second sub-conduits (2.2, 2.3), each sub-conduit subjecting combustion air to different degrees of flow resistance.

    摘要： PCT No. PCT/DK89/00044 Sec. 371 Date Sep. 6, 1990 Sec. 102(e) Date Sep. 6, 1990 PCT Filed Feb. 27, 1989 PCT Pub. No. WO89/08750 PCT Pub. Date Sep. 21, 1989.A vortex chamber valve for controlling fluid flow in a pipe system comprising a housing forming a vortex chamber having a curved sidewall, an inlet opening, and an outlet opening; an inlet valve disposed at an upstream side of the vortex chamber inlet opening having a main section and an edge section, wherein the edge section has a deflecting surface protruding away from the main section and towards the upstream side of the inlet valve, the edge section of the inlet valve covers a part of the inlet opening, so that, when upstream fluid levels rise at least up to the deflecting surface, the deflecting surface acts on the inflowing fluid to cause contraction in the inlet opening of the cross-sectional area of the inflowing fluid.

    摘要： The fluidic oscillator (14) includes a resonant fluid circuit having a fluid inertance and a dynamic fluid compliance. The inertance is a conduit (4) interconnecting two locations (16a, 16b) of a chamber on each side of a working fluid jet issuing into one end of the chamber (3), the inertance conduit transfers working fluid between the two locations. Through one or more output orifices (10), located at the opposite end of chamber (3), the fluid exits from an exit region (11) which is shaped to facilitate formation of a vortex (the dynamic compliance) from the entering fluid. The flow pattern in chamber (3), specially the vortex in exit region (11) provide flow aspiration on one side and surplus of flow on the opposite side of chamber (3), which effects accelerate and respectively decelerate the fluid in the inertance conduit (4) such as to cause reversal of the vortex after a time delay given by the inertance. The vortex in the exit region will cyclically alternate in velocity and direction of rotation to direct outflow through the output orifice such as to produce a cyclically repetitive side-to-side sweeping stream whose direction is determined, at any instant in time, as a function of the vectorial sum, at the output orifice, of the tangential vortex flow spin velocity vector and the static pressure vector and the dynamic pressure component, both directed radially from the vortex. By changing these parameters and by appropriately configuring the oscillator, sweep angle, oscillation frequency, distribution, outflow velocity, break up into droplets, etc. can be controlled over large ranges.
