Abstract

An adjustable nozzle assembly includes a receiver having a fluid inlet configured to be fluidly coupled to a fluid source and an internal surface defining a reception chamber fluidly coupled to the fluid inlet, a swivel member disposed in the reception chamber of the receiver, a nozzle coupled to the swivel member, fluidly coupled to the reception chamber, and configured to discharge fluid along a discharge axis, and a restriction member coupled to the receiver such that the swivel member is positioned between the receiver and the restriction member. The swivel member has an external surface including a substantially spherical external surface portion in contact with the internal surface of the receiver. The restriction member has a surface geometry defining a passageway through which the nozzle extends, and the surface geometry limits rotation of the swivel member within the receiver.

First claim

What is claimed is:

1. An adjustable nozzle assembly comprising:
a receiver having a first inlet, a first outlet, and a first internal passageway extending between the first inlet and the first outlet, the receiver including a reception chamber centered about a first axis, the reception chamber being in fluid communication with the first internal passageway;
a swivel member disposed in the reception chamber of the receiver, the swivel member having a second inlet fluidly coupled to the first outlet, a second outlet, and a second internal passageway extending between the second inlet and the second outlet;
a nozzle coupled to the swivel member and fluidly coupled to the second internal passageway, wherein the nozzle is centered about a second axis;
a restriction member formed as a single continuous piece having an internal surface including a first planar portion configured to engage a second planar portion of an external surface of the swivel member to limit rotation of the swivel member relative to the restriction member; and
a securement member defining an aperture that receives the restriction member and coupling the restriction member to the receiver, wherein the securement member is directly coupled to the receiver and configured to selectively force the restriction member toward the receiver, and wherein the securement member is movable relative to the restriction member.

2. The adjustable nozzle assembly of claim 1 , wherein the securement member is configured to limit rotation of the restriction member to rotation about the first axis.

3. The adjustable nozzle assembly of claim 2 , wherein the swivel member is configured to rotate about the first axis through a maximum rotation angle of at least 360 degrees with respect to the receiver.

4. The adjustable nozzle assembly of claim 3 , wherein a bend angle is defined between the first axis and second axis, wherein the bend angle is adjustable from zero degrees to a maximum bend angle, and wherein the maximum bend angle ranges from greater than thirty degrees to less than sixty degrees.

5. The adjustable nozzle assembly of claim 2 , wherein the securement member is configured to selectively fixedly couple the restriction member and the swivel member to the receiver.

6. The adjustable nozzle assembly of claim 1 , wherein the second internal passageway of the swivel member is centered about and extends along a fourth axis that is skewed with respect to the second axis of the nozzle.

7. The adjustable nozzle assembly of claim 1 , wherein the swivel member has a substantially spherical external surface portion in contact with an internal surface of the receiver;
wherein the nozzle is configured to discharge fluid along the second axis; and
wherein the restriction member is coupled to the receiver such that the swivel member is positioned between the receiver and the restriction member, and wherein the restriction member defines a passageway through which the nozzle extends.

8. The adjustable nozzle assembly of claim 7 , wherein the restriction member is configured to rotate relative to the receiver about the first axis.

9. The adjustable nozzle assembly of claim 7 , wherein the second internal passageway of the swivel member is skewed with respect to the second axis of the nozzle.

10. The adjustable nozzle assembly of claim 9 , wherein when the second axis of the nozzle is aligned with the first axis, the second inlet of the second internal passageway of the swivel member defines a first cross-sectional area through which fluid can flow, and wherein when the second axis is skewed with respect to the first axis, the second inlet of the second internal passageway of the swivel member defines a second cross-sectional area through which fluid can flow that is the same as the first cross-sectional area.

11. The adjustable nozzle assembly of claim 1 , wherein the securement member is configured to selectively force the restriction member and the swivel member toward the receiver to fix the orientation of the swivel member.

12. The adjustable nozzle assembly of claim 1 , wherein engagement between the first planar portion and the second planar portion permits rotation of the swivel member relative to the restriction member about a third axis that intersects and is perpendicular to the first axis, and wherein the third axis is substantially perpendicular to the first planar portion and the second planar portion.

13. The adjustable nozzle assembly of claim 1 , wherein engagement between the first planar portion and the second planar portion permits rotation of the swivel member relative to the restriction member about only a third axis that intersects and is perpendicular to the first axis.

14. The adjustable nozzle assembly of claim 1 , wherein the swivel member has a substantially spherical external surface portion positioned opposite the first planar portion.

15. The adjustable nozzle assembly of claim 1 , wherein the first planar portion is configured to engage the second planar portion to limit rotation of the swivel member relative to the restriction member such that the swivel member is rotatable relative to the receiver about the first axis only when the restriction member rotates about the first axis, and wherein the swivel member is rotatable relative to the receiver about a third axis that intersects and is perpendicular to the first axis.

16. An adjustable nozzle assembly comprising:
a receiver having a first inlet, a first outlet, and a first internal passageway extending between the first inlet and the first outlet, the receiver including a reception chamber centered about a first axis, the reception chamber being in fluid communication with the first internal passageway;
a swivel member disposed in the reception chamber of the receiver, the swivel member having a second inlet fluidly coupled to the first outlet, a second outlet, and a second internal passageway extending between the second inlet and the second outlet;
a nozzle coupled to the swivel member and fluidly coupled to the second internal passageway, wherein the nozzle is centered about a second axis;
a restriction member having an internal surface including a first flat portion configured to engage a second flat portion of an external surface of the swivel member to limit rotation of the swivel member relative to the restriction member such that the swivel member is rotatable relative to the receiver about the first axis only when the restriction member rotates about the first axis, and wherein the swivel member is rotatable relative to the receiver through a range of motion about a third axis that intersects and is perpendicular to the first axis; and
a securement member coupling the restriction member to the receiver, wherein the securement member is directly coupled to the receiver; and
wherein the first internal passageway and the second internal passageway are in fluid communication internally throughout the entirety of the range of motion.

17. The adjustable nozzle assembly of claim 16 , wherein the third axis is substantially perpendicular to the first flat portion and the second flat portion.

18. The adjustable nozzle assembly of claim 16 , wherein the restriction member is formed as a single continuous piece.

19. An adjustable nozzle assembly comprising:
a receiver having a first inlet, a first outlet, and a first internal passageway extending between the first inlet and the first outlet, the receiver including a reception chamber centered about a first axis and having a first cross-sectional area, the reception
