Abstract
A fluidic oscillator includes an oscillator body having two attachment walls defining an oscillating chamber therebetween, an inlet duct communicatively extended from the oscillating chamber for guiding a flow of fluid entering into the oscillating chamber, an outlet duct communicatively extended from the oscillating chamber for guiding the flow of fluid exiting from the oscillating chamber, a flow splitter provided at the outlet duct to communicate with the oscillating chamber, and two feedback channels communicating with the oscillating chamber. Each of the attachment walls has an upstream portion and a downstream portion integrally extended therefrom as a step shouldering manner to form a modulating shoulder for modulating an oscillation of the flow within the oscillation chamber so as to stabilize the flow of the fluid to pass through the oscillator body.
