Abstract
Abstract A spray nozzle is in the form of a chamber 1 having end walls 2 and 3 each with an aperture 4, 5 respectively. The fluid to be sprayed is drawn from a feed tube 6 and is circulated within the chamber 1 by a deflector plate 8. A pressurized fluid, e.g. compressed air, is fed via a pipe 11 through the aperture 4 and through the center of the chamber 1. This pressurized fluid carries with it droplets of the fluid to be sprayed which emerge at a high velocity from the nozzle 12 carried by the aperture 5. A plurality of spray nozzles may be connected in cascade to provide a spray system. Because of the high-velocity spray produced, the device may conveniently be used to cool the inner surface of a housing using a deflector plate 14.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
145 words
A spray device comprising: a body having two end walls between which is defined a substantially cylindrical chamber, each end wall having defined therein a substantially central aperture; first feeding means connected to the body for tangentially directing a first fluid into the chamber to form therein a vortex aligned on an axis passing through the apertures; second feeding means connected to the body via one aperture for directing a second fluid into the chamber through the said one aperture so as to flow towards the other aperture, the second fluid passing through the eye of the vortex of first fluid and carrying particles thereof away from the inner surface of the vortex through the other aperture in the form of a spray; and exhausting means connected to the body for enabling first fluid not carried into the said spray to escape from the chamber.
Claim 2
Dependent Claim
145 words
A spray device comprising: a body having two end walls between which is defined a substantially cylindrical chamber, each end wall having defined therein a substantially central aperture; first feeding means connected to the body for tangentially directing a first fluid into the chamber to form therein a vortex aligned on an axis passing through the apertures; second feeding means connected to the body via one aperture for directing a second fluid into the chamber through the said one aperture so as to flow towards the other aperture, the second fluid passing through the eye of the vortex of first fluid and carrying particles thereof away from the inner surface of the vortex through the other aperture in the form of a spray; and exhausting means connected to the body for enabling first fluid not carried into the said spray to escape from the chamber.
Claim 3
Dependent Claim
42 words
A spray device according to claim 1, wherein the first feeding means and the exhausting means comprise a single fluid duct disposed tangentially with respect to, and communicating with, the said chamber at an intermediate point along the length of the duct.
Claim 4
Dependent Claim
30 words
A spray according to claim 2 wherein a deflector is disposed in the said single fluid duct near the said intermediate point for deflEcting first fluid into the said vortex.
Claim 5
Dependent Claim
64 words
A spray device according to claim 2, wherein the first feeding means comprises a first fluid duct disposed tangentially with respect to, and communicating with the said chamber at a first point on the circumference thereof, and the exhausting means comprises a second fluid duct disposed tangentially with respect to, and communicating with, the said chamber at a second point on the circumference thereof.
Claim 6
Dependent Claim
44 words
A spray device according to claim 1, wherein the said one aperture has disposed therein deflecting means for imparting a radial component of velocity to the second fluid to increase the degree of contact thereof with the said inner surface of the said vortex.
Claim 7
Dependent Claim
22 words
A spray device according to claim 5, wherein a convergent nozzle is disposed outside the said chamber adjacent the said other aperture.
