Patent ID: 7021562

Claim:
An injector for distributing liquid sprays, comprising: an inlet fitting including a port to receive liquid, a stem assembly supported by the fitting, the stem assembly including an internal circuit fluidly connected to the port, and a manifold supported by the stem assembly and including an internal passage connected to the internal circuit in the stem assembly, the manifold including an elongated manifold segment formed of multiple plates and having a plurality of nozzles spaced along the manifold segment, wherein each of the nozzles is fluidly connected to the internal passage for delivering sprays of liquid, wherein each nozzle includes a swirl chamber formed in at least one of the plates having a shape such that liquid to be sprayed can move therein in a vortex motion toward the center of the swirl chamber, at least one non-radial feed slot intersecting the swirl chamber for directing liquid to the swirl chamber, a spray orifice at the center of the swirl chamber such that liquid to be sprayed can move from the swirl chamber to the spray orifice and then exit the spray orifice in a thin film which soon atomizes into a fine droplet mist.
