Abstract
An atomizer spray plate including a body having an inlet surface and an exit surface, a swirl chamber within the body and adjacent to the inlet surface, an atomizer hole extending through the body from the swirl chamber to the exit surface, and a plurality of elongated protrusions upon the inlet surface extending radially from the swirl chamber, wherein the plurality of elongated protrusions define a plurality of venturi inlets to the swirl chamber between adjacent protrusions.
Claims20
An atomizer spray plate, comprising:
- a body having an inlet surface and an exit surface;
- a swirl chamber within said body and adjacent to the inlet surface;
- an atomizer hole extending through the body from said swirl chamber to the exit surface;
- and
- a plurality of elongated protrusions upon the inlet surface extending radially from said swirl chamber;
- wherein said plurality of elongated protrusions define a plurality of venturi inlets to said swirl chamber between adjacent protrusions;
- wherein a fluid flows from the inlet surface through said plurality of venturi inlets into the swirl chamber;
- wherein said plurality of venturi inlets are shaped such as to receive the fluid at a first velocity and provide the fluid to said swirl chamber at a second increased velocity in accordance with the Venturi effect;
- and
- wherein each of said plurality of venturi inlets has a first width and a second width downstream from the first width with respect to the direction of the fluid flow, the second width being greater than the first width.
