Abstract (en)
[origin: US4597529A] A self-regulating spray nozzle is provided which includes a chamber for receiving both product to be sprayed and a driving fluid. A moveable component is provided for selectively varying the cross-sectional area of an opening provided in an output passage from the chamber in response to pressure developed within the interior of the chamber. A mechanical counter-force is exerted on the moveable component to tend to close the output passage opening of the chamber against the force of the pressure developed in the chamber, and which at least partially overcomes the force of the pressure developed within the interior of the chamber to thereby maintain the pressure drop through the output passage opening substantially constant.
