Abstract: 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.

Abstract: A fluidic oscillator which is free of feedback passages has an oscillation chamber having a length greater than its width, a pair of mutually facing and complementary-shaped sidewalls (13, 14), planar top and bottom walls (141, 142), and first and second end walls (15). An input power nozzle (17) is formed in said first end wall (15) having a width W and a depth D, for issuing a stream of fluid into the oscillation chamber, and forms alternately pulsating, cavitation-free vortices in said oscillation chamber on each side of the stream. An interconnect passage or channel (107) proximate the downstream end wall (103) enlarges the sweep angle and improves periodicity of the oscillations. The outlet wall (148) is hingedly connected to a chamber wall and the chamber is such that it can be molded with the outlet wall hingedly connected thereto in one molding and forms one side of the inteconnect passage or channel.

Abstract: A powder spray gun (10) comprises a tubular housing (12) having ambient air flow passages (40) located in the side wall thereof medially of the opposite ends. A pair of air flow amplifiers (14, 16) are mounted in the housing on opposite sides of the ambient air flow passages and are so oriented that compressed air supplied to the upstream one of these amplifiers, the so called suspension amplifier (14) is operable to draw ambient air into the outlet end of the suspension amplifier, and compressed air supplied to the downstream amplifier (16), the so called pattern amplifier, is operable to draw ambient air into the inlet end of the pattern amplifier (16). The amplifiers (14, 16) are secured within the housing by end caps (18, 20) which are sealingly secured onto the ends of the housing by bayonet pin and slot connectors (33).
