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 complementarily-shaped sidewalls and planar top and bottom walls, and first and second end walls. An input power nozzle is formed in said first end wall having a width W and a depth D, for issuing a stream of fluid into the oscillation chamber, and form alternately pulsating, cavitation-free vortices in said oscillation chamber on each side of the stream. An outlet opening formed in the downstream end wall and axially aligned with the power nozzle and has a width and depth such that internal pressure in the oscillation chamber is greater than ambient. The outlet wall 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.
