Abstract

Claims (46)

1. A fluid distributor, comprising:

a component configured for selective rotation about a central axis of the fluid distributor;

a fluid input;

a first fluid output in selective fluid communication with the fluid input; and

a second fluid output in selective fluid communication with the fluid input; and,

a fluid flow divider plate comprising:

a plurality of first internal passages selectively in fluid communication with the fluid input and the first fluid output;

a plurality of second internal passages selectively in fluid communication with the fluid input and the second fluid output;

wherein the plurality of first internal passages and the plurality of second passages are alternatingly disposed next to each other about the central axis so that each of the first internal passages is substantially angularly bounded in both directions by second internal passages and so that each of the second internal passages is substantially angularly bounded in both directions by first internal passages; and,

wherein rotation of the component in a first direction about the central axis alternates selection between the first fluid output and the second fluid output and at least one of (1) the component is configured to rotate about the central axis by at least 360° in the first direction and such rotation of the component about the central axis by at least 360° provides at least four alternations between selection of the first fluid output and the second fluid output and (2) selection of the second fluid output is the next available fluid output for selection in response to rotating the component about the central axis away from a position of the component in which the first fluid output is selected.

2. The fluid distributor of claim 1 , wherein the first fluid output is configured to provide a needle spray fluid flow pattern and wherein the second fluid output is configured to provide a substantially consolidated fluid flow pattern.

3. The fluid distributor of claim 1 , wherein the component comprises a portion of an exterior shell of the fluid distributor.

4. The fluid distributor of claim 1 , wherein the rotation of the component about the central axis moves the component longitudinally along the central axis.

5. The fluid distributor of claim 1 , wherein the component is configured to resist longitudinal movement along the central axis in the absence of rotational movement of the component about the central axis.

6. The fluid distributor of claim 1 , further comprising:

a plurality of fluid flow selection seals disposed upstream relative to the fluid flow divider plate; and

a fluid distribution plate disposed between the plurality of fluid flow selection seals and the fluid flow divider plate, wherein the fluid distribution plate comprises a plurality of fluid distribution apertures configured for selective angular alignment with the plurality of fluid flow selection seals in response to rotation of the component about the central axis.

7. A method of selectively distributing a fluid, comprising:

providing a fluid to a fluid input; and

providing a component that allows selection between a first fluid output and a second fluid output in response to rotation of the component about an axis; and,

providing a fluid flow divider plate comprising:

a plurality of first internal passages selectively in fluid communication with the fluid input and the first fluid output;

a plurality of second internal passages selectively in fluid communication with the fluid input and the second fluid output;

wherein the plurality of first internal passages and the plurality of second passages are alternatingly disposed next to each other about the central axis so that each of the first internal passages is substantially angularly bounded in both directions by second internal passages and so that each of the second internal passages is substantially angularly bounded in both directions by first internal passages; and,

wherein when the component is in a position in which the first fluid output is selected (1) the next available fluid output selection in response to rotation of the component about the axis in a first direction is the second fluid output and (2) the next available fluid output selection in response to rotation of the component about the axis in a second direction is the second fluid output.

8. The method of claim 7 , further comprising:

wherein when the component is in a position in which the second fluid output is selected (1) the next available fluid output selection in response to rotation of the component about the axis in the first direction is the first fluid output and (2) the next available fluid output selection in response to rotation of the component about the axis in a second direction is the first fluid output.

9. The method of claim 7 , wherein rotation of the component about the axis by 360° alternates selection between the first fluid output and the second fluid output at least four times.

10. The method of claim 7 , wherein passing fluid through the first fluid output comprises distributing the fluid in a plurality of substantially distinct fluid streams.

11. The method of claim 7 , wherein passing fluid through the first fluid output comprises distributing the fluid in a substantially consolidated fluid stream.

12. The method of claim 7 , wherein selection between the first fluid output and the second fluid output requires rotation of the component about the axis and cannot be achieved only by longitudinal movement of the component along the axis.

13. The method of claim 7 , wherein the component is constrained to require rotation of the component about the axis to longitudinally move the component along the axis.

14. A fluid distributor, comprising:

a fluid flow divider plate comprising:

a plurality of first internal passages;

a plurality of second internal passages;

wherein the plurality of first internal passages and the plurality of second passages are alternatingly disposed next to each other about the central axis so that each of the first internal passages is substantially angularly bounded in both directions by second internal passages and so that each of the second internal passages is substantially angularly bounded in both directions by first internal passages;
