Abstract
Abstract A mechanical break-up spray nozzle comprises two members which define between them, by means of a channel in at least one of the members, a passage having one end closed and its opposite end communicating with an inlet cavity, an outlet orifice of the nozzle opening into the passage intermediate its ends and the cross-sectional dimensions of the passage being small in relation to those of the inlet cavity. A nozzle member is also provided which incorporates the inlet cavity, the groove and also the outlet orifice.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
158 words
In a mechanical break-up spray nozzle comprising material defining an inlet cavity and an outlet orifice, the improvement which comprises: a first member defining a groove into which said orifice opens intermediate the ends of the groove; a second member engaged with said first member to seal along edge portions of said groove so as to define with said first member an elongate passage closed at one end and communicating with said inlet cavity at a region spaced from said one end, and said passage throughout its extent from said region to said one end being substantially non-divergent with a cross-sectional area the dimensions of which are small in relation to said extent and in relation to cross-sectional dimensions of said cavity; and portions of said nozzle defining said orifice with a slit-form opening into said passage between said one end and said region and with opposed, outwardly diverging, surfaces extending from respective major surfaces of said opening.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
26 words
A nozzle as claimed in claim 1, wherein one of said members is hollow and the other of said members is engaged within said one member.
Claim 4
Dependent Claim
22 words
A nozzle as claimed in claim 2, wherein said first member is said other member and said second member defines said orifice.
Claim 5
Dependent Claim
37 words
A nozzle as claimed in claim 3, wherein said first member defines a plurality of different grooves and is rotatable relative to the second member to place said orifice in communication with successive ones of said grooves.
Claim 6
Dependent Claim
23 words
A nozzle as claimed in claim 3, wherein said second member defines a through hole closed at one end by said first member.
Claim 7
Dependent Claim
49 words
A nozzle as claimed in claim 5, wherein said first member has a projection for limiting the insertion into said hole of a fluid feed tube to maintain a gap between said first member and said tube to provide communication between said passage and the interior of said tube.
Claim 8
Dependent Claim
20 words
A nozzle as claimed in claim 3, wherein said first member is the valve stem of a discharge control valve.
Claim 9
Dependent Claim
19 words
A nozzle as claimed in claim 2, wherein the first member is said one member and defines said orifice.
Claim 10
Dependent Claim
20 words
A nozzle as claimed in claim 8, wherein a projecting, curved, wall portion of said first member defines said groove.
Claim 11
Dependent Claim
47 words
A nozzle as claimed in claim 8, wherein the second member contains a feed chamber communicating with said passage via a substantially U-shaped flow path defined in said nozzle so that the directions of flow in said chamber and said passage are substantially opposite to one another.
Claim 12
Dependent Claim
28 words
A nozzle as claimed in claim 1, wherein a portion of said first member defines an end wall of said groove at said one end of said passage.
Claim 13
Dependent Claim
25 words
A nozzle as claimed in claim 1, wherein said second member defines an end wall of said passage at said one end of said passage.
Claim 14
Dependent Claim
23 words
A nozzle as claimed in claim 1, wherein said opening extends over no more than five twelfths of the circumference of said passage.
Claim 15
Dependent Claim
18 words
A nozzle as claimed in claim 1, wherein the maximum cross-sectional dimension of said passage is 0.050 inches.
Claim 16
Dependent Claim
28 words
A nozzle as claimed in claim 1, wherein the ratio of maximum cross-sectional dimensions of said cavity and said passage is in the range from 3:1 to 20:1.
Claim 17
Dependent Claim
39 words
A nozzle as claimed in claim 1, wherein the passage has an elongated cross-sectional form the length direction of which extends at an angle to the direction at right angles to the axis of said passage through said orifice.
Claim 18
Dependent Claim
22 words
A nozzle as claimed in claim 1, wherein said nozzle is operatively engaged with a pressurized container for dispensing formulations under pressure.
Claim 19
Dependent Claim
34 words
A nozzle as claimed in claim 1, wherein said two opposed surfaces diverge towards the outside of said nozzle at different angles to the direction of said extent of said passage past said opening.
Claim 20
Dependent Claim
26 words
A nozzle as claimed in claim 18, wherein one of said surfaces is substantially at right angles to said extent of said passage past said opening.
Claim 21
Dependent Claim
25 words
A nozzle as claimed in claim 19, wherein said one surface is nearer said one end of said passage than the other of said surfaces.
