Abstract
A fluidic oscillator can include an input, first and second outputs on opposite sides of a longitudinal axis of the oscillator, whereby a majority of fluid which flows through the oscillator exits the oscillator alternately via the first and second outputs, first and second paths from the input to the respective first and second outputs, and wherein the first and second paths cross each other between the input and the respective first and second outputs. Another oscillator can include an input, first and second outputs, whereby a majority of fluid flowing through the fluidic oscillator exits the oscillator alternately via the first and second outputs, first and second paths from the input to the respective first and second outputs, and a feedback path which intersects the first path, whereby reduced pressure in the feedback path influences the majority of fluid to flow via the second path.
