Abstract
Abstract The invention is directed to a method of forming a spray, to a spray nozzle and to a method of making a spray nozzle. The method of forming a spray includes the step of directing a jet of liquid onto an apertured diffuser element of coniform which diverges in the flow direction of the jet of liquid. The spray nozzle includes a nozzle and an apertured diffuser element of coniform opposite the nozzle outlet and diverging away from the nozzle. The invention also shows that an annular deflector element is provided around the diffuser element.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
70 words
A spray nozzle including a nozzle, an apertured diffuser element of coniform, and support means to support the diffuser element opposite and spaced from the nozzle outlet and diverging away from the nozzle, the diffuser element having a plurality of apertures spaced about its polar axis and the sides of each aperture diverging in a direction away from the nozzle relative to an axis parallel to the said polar axis.
Claim 2
Dependent Claim
70 words
A spray nozzle including a nozzle, an apertured diffuser element of coniform, and support means to support the diffuser element opposite and spaced from the nozzle outlet and diverging away from the nozzle, the diffuser element having a plurality of apertures spaced about its polar axis and the sides of each aperture diverging in a direction away from the nozzle relative to an axis parallel to the said polar axis.
Claim 3
Dependent Claim
41 words
A spray nozzle according to claim 1, in which the radially outward side of each aperture of the diffuser element is inclined to the said polar axis at an inclination which is proportional to its distance from the said polar axis.
Claim 4
Dependent Claim
17 words
A spray nozzle according to claim 1, which is an integral molding of a synthetic plastic material.
Claim 5
Dependent Claim
51 words
A spray nozzle including a nozzle, an apertured diffuser element of coniform, support means to support the diffuser element opposite and spaced from the nozzle outlet and diverging away from the nozzle, and an annular deflector element around the diffuser element and mounted with a radial clearance space between the elements.
Claim 6
Dependent Claim
51 words
A spray nozzle including a nozzle, an apertured diffuser element of coniform, support means to support the diffuser element opposite and spaced from the nozzle outlet and diverging away from the nozzle, and an annular deflector element around the diffuser element and mounted with a radial clearance space between the elements.
Claim 7
Dependent Claim
29 words
A spray nozzle according to claim 4, in which the annular deflector element has a plurality of circumferentially spaced deflecting surfaces at different degrees of divergence from the nozzle.
Claim 8
Dependent Claim
54 words
A spray nozzle including a nozzle, an apertured diffuser element, support means to support the diffuser element opposite and spaced from the nozzle outlet, and deflecting means around the diffuser element to deflect washoff liquid from the rear side of the diffuser element relative to the nozzle in a direction away from the nozzle.
Claim 9
Dependent Claim
54 words
A spray nozzle including a nozzle, an apertured diffuser element, support means to support the diffuser element opposite and spaced from the nozzle outlet, and deflecting means around the diffuser element to deflect washoff liquid from the rear side of the diffuser element relative to the nozzle in a direction away from the nozzle.
Claim 10
Dependent Claim
39 words
A spray nozzle according to claim 6 in which the deflecting means comprises an annular element radially spaced from the diffuser element and having a plurality of circumferentially spaced deflecting surfaces at different degrees of divergence from the nozzle.
Claim 11
Dependent Claim
30 words
A method of making a spray nozzle as claimed in claim 1, which includes molding the nozzle in a synthetic plastic material and forming the apertures during the molding operation.
Claim 12
Independent Claim
86 words
A method for forming a spray which includes directing a jet of liquid onto an apertured diffuser element of coniform which diverges in the flow direction of the jet of liquid so that liquid passing through the apertures is diffused and emerges in the form of a spray while the liquid not passing through the apertures is washed off the diffuser element in a direction transverse to the flow direction of the jet of liquid, and which further includes deflecting the washoff liquid towards the spray.
Claim 13
Independent Claim
86 words
A method for forming a spray which includes directing a jet of liquid onto an apertured diffuser element of coniform which diverges in the flow direction of the jet of liquid so that liquid passing through the apertures is diffused and emerges in the form of a spray while the liquid not passing through the apertures is washed off the diffuser element in a direction transverse to the flow direction of the jet of liquid, and which further includes deflecting the washoff liquid towards the spray.
Claim 14
Dependent Claim
27 words
A method according to claim 9, in which the washoff liquid is deflected in adjacent zones of different degrees of divergence circumferentially spaced about the diffuser element.
