Patent ID: 6860157

Claim:
A fluidic oscillator, comprising: an oscillator body having two attachment walls defining an oscillating chamber therebetween, an inlet duct communicatively extended from said oscillating chamber for guiding a flow of fluid entering into said oscillating chamber, an outlet duct communicatively extended from said oscillating chamber to align with said inlet duct for guiding said flow of fluid exiting from said oscillating chamber, a flow splitter provided at said outlet duct to communicate with said oscillating chamber, and two feedback channels communicating with said oscillating chamber; wherein each of said feedback channels is extended from said outlet duct at said flow splitter to said inlet duct for splitting said flow of fluid to flow from said oscillating chamber back to said inlet duct; wherein each of said 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 said flow within said oscillation chamber so as to stabilize said flow of fluid to pass through said oscillator body.
