Principle of the locator: What is the relationship between the baffle, nozzle, throttle hole, and amplifier?

Thread Content

I’ve never really understood the principle of positioners: what is the relationship between the baffle, nozzle, throttle orifice, and amplifier? Why does the back pressure at the nozzle increase as the baffle gets closer to it, and is this amplified by the amplifier? What is the function of the throttle hole? What is the state of the nozzle when the baffle is not close? How to understand it?
