Abstract
Abstract Spray nozzles are described comprising a floating deflector supported close to and in alignment with the nozzle orifice so as to be impinged by the jet issuing therefrom, the deflector being floatingly mounted so as to be movable laterally of, towards, and away from the nozzle orifice, and being formed with a central recess on the face thereof impinged by the jet effective to automatically self-center the deflector with respect to the orifice. The nozzle further includes limiting means limiting the floating movement of the deflector with respect to the nozzle orifice.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
A spraying device comprising a nozzle formed with an outlet orifice through which the fluid issues in the form of a jet; a deflector supported close to and in alignment with the nozzle orifice so as to be impinged by the jet issuing therefrom; said deflector being floatingly mounted with respect to the nozzle so as to be movable in a lateral direction with respect to its orifice; said deflector being formed with a recess centrally of the face thereof impinged by the jet which recess is effective to automatically selfcentre the deflector with respect to the orifice upon the issuance of the jet therefrom; and limiting means limiting the floating movement of the deflector with respect to the nozzle orifice.
Claim 2
Dependent Claim
121 words
A spraying device comprising a nozzle formed with an outlet orifice through which the fluid issues in the form of a jet; a deflector supported close to and in alignment with the nozzle orifice so as to be impinged by the jet issuing therefrom; said deflector being floatingly mounted with respect to the nozzle so as to be movable in a lateral direction with respect to its orifice; said deflector being formed with a recess centrally of the face thereof impinged by the jet which recess is effective to automatically selfcentre the deflector with respect to the orifice upon the issuance of the jet therefrom; and limiting means limiting the floating movement of the deflector with respect to the nozzle orifice.
Claim 3
Dependent Claim
42 words
A device according to claim 1, wherein said floatingly mounting deflector is also movable inwardly and outwardly towards and away from the nozzle orifice, and is biased to close the nozzle orifice upon the termination of the issuance of the jet therefrom.
Claim 4
Dependent Claim
23 words
A device according to claim 2, wherein said floatingly mounted deflector overlies the nozzle orifice and is biassed to close same by gravity.
Claim 5
Dependent Claim
21 words
A device according to claim 1, wherein said recess in the deflector is of slightly larger diameter than the nozzle orifice.
Claim 6
Dependent Claim
59 words
A device according to claim 1, wherein the limiting means comprises a rod of smaller diameter than the nozzle orifice and passing therethrough, the outer end of the rod being attached to the deflector and the inner end of the rod including a stop limiting the outward movement of the rod and deflector with respect to the nozzle orifice.
Claim 7
Dependent Claim
37 words
A device according to claim 5, wherein said stop includes a cross-bar carried at the inner end of the rod to limit the outward movement thereof while permitting the fluid to pass therearound to the nozzle orifice.
Claim 8
Dependent Claim
77 words
A device according to claim 6, wherein the deflector includes a second recess formed on the face thereof opposite to the first recess, and wherein the limiting means comprises a first portion attached to the nozzle, and a second portion seatable within the second recess of the deflector, the latter recess being of larger dimensions than said second portion of the limiting means to permit said floating movement of the deflector with respect to the nozzle orifice.
Claim 9
Dependent Claim
57 words
A device according to claim 7, wherein said first portion of the limiting means includes a U-shaped rod in which the two legs of the rod are attached to the nozzle, and said second portion of the limiting means includes a second rod carried by the U-shaped rod and seatable within the second recess of the deflector.
Claim 10
Dependent Claim
42 words
A device according to claim 1, wherein the face of the deflector facing the nozzle orifice is substantially flat except for the recess formed therein and is of smaller outer diameter than the confronting face of the nozzle having the outlet orifice.
Claim 11
Dependent Claim
32 words
A device according to claim 9, wherein said confronting face of the nozzle having the orifice is also substantially flat but is formed with an upwardly inclined surface at its outer margin.
