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.
