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.

Claims20

Dependent claims

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.

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 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, the second inlet having a second cross-sectional area;
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 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;
and
a securement member coupling the restriction member to the receiver, wherein the securement member is directly coupled to the receiver, and wherein the securement member is aligned with the first axis of the receiver;
wherein the first cross-sectional area is greater than the second cross-sectional area;
and
wherein a fluid can flow through the entirety of the first cross-sectional area and the entirety of the second cross-sectional area.
