Abstract

An atomizer includes an atomizer body with a plurality of air passages defined therethrough from an upstream end of the atomizer body to a downstream end thereof. The air passages together define an air circuit through the atomizer body. A fuel circuit is defined in the atomizer body extending from a fuel inlet to a respective fuel outlet opening into each air passage. The air passages can be arranged circumferentially about a central axis defined by the atomizer body. The fuel circuit can include a manifold extending circumferentially about the atomizer body in fluid communication with a fuel opening in each respective air passage.

First claim

What is claimed is:

1 . An atomizer comprising:
an atomizer body with an air passage defined therethrough from an upstream end of the atomizer body to a downstream end thereof; and a fuel circuit defined in the atomizer body extending from a fuel inlet to a fuel outlet opening into the air passage, wherein the fuel outlet includes a direct, cross-flow injection port into the air passage.

2 . An atomizer as recited in claim 1 , wherein the fuel circuit defines a fuel passage from the fuel inlet to the fuel outlet that is angled obliquely relative to the air passage.

3 . An atomizer as recited in claim 2 , wherein the fuel circuit opens tangentially into the air passage relative to a flow path defined through the air passage to induce a tangential component of fuel flow in the air passage.

4 . An atomizer as recited in claim 2 , wherein the fuel circuit opens into the air passage without a tangential component, with an injection direction directed along a central diameter plane of the air passage.

5 . An atomizer as recited in claim 1 , wherein the fuel outlet defines a radial injection direction relative to the air passage.

6 . An atomizer comprising:
an atomizer body with a plurality of air passages defined therethrough from an upstream end of the atomizer body to a downstream end thereof, wherein the air passages together define an air circuit through the atomizer body; and a fuel circuit defined in the atomizer body extending from a fuel inlet to a respective fuel outlet opening into each of the air passages respectively, wherein each fuel outlet includes a direct, cross-flow injection port into the air passage.

7 . An atomizer as recited in claim 6 , wherein the air passages are arranged circumferentially about a central axis defined by the atomizer body.

8 . An atomizer as recited in claim 6 , wherein the fuel circuit includes a manifold extending circumferentially about the atomizer body in fluid communication with a fuel opening in each respective air passage.

9 . An atomizer as recited in claim 6 , wherein the fuel circuit defines a fuel passage from the fuel inlet to the fuel outlet that is angled obliquely relative to the air passage.

10 . An atomizer as recited in claim 9 , wherein each fuel circuit opens tangentially into each respective air passage relative to a flow path defined through the air passage to induce a tangential component of fuel flow in the air passage.

11 . An atomizer as recited in claim 6 , wherein the fuel circuit opens into each respective air passage without a tangential component, with an injection direction directed along a central diameter plane of the air passage.

12 . An atomizer as recited in claim 6 , wherein each fuel outlet defines a radial injection direction relative to the respective air passage.
