Abstract
A reversing chamber oscillator has an oscillation chamber with a reversing wall, a centrally located power nozzle for issuing a jet of liquid toward the reversing wall, and a pair of liquid passages from the reversing chamber on each side of the power nozzle, respectively, for alternately issuing periodic pulses of liquid. The outlet passages are smoothly extended to intersect directly at a common outlet and are dimensioned and angulated relative to each other to control the sweep angle of a liquid jet which is periodically swept in the common outlet and issued to ambient. The pair of fluid passages have an upstream end at the reversing chamber and a downstream end at the common outlet and each passage has an outer wall which, with the reversing wall, define an oval.
