Abstract
Abstract The disclosure illustrates a nozzle assembly comprising inlet and outlet plates stacked on either side of a spacer sleeve. The outlet plate has an elongated slot and the inlet plate has a pair of ports offset from and on opposite sides of the slot to promote turbulence within the spacer sleeve. The outlet plate may be made of flexible material so that for higher flow rates the plate deforms and provides a larger opening.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
94 words
A flat spray nozzle assembly comprising: a relatively thin spacer having a central through passage; an inlet plate stacked on one side of said spacer and having a plurality of spaced ports forming inlets to said passage; and an outlet plate stacked on the opposite side of said spacer and having a narrow elongated slot for discharge of fluid from said passage in a flat spray, said spaced ports lying on opposite sides of and being offset from said elongated slot, whereby the flow from said ports creates a turbulence along said elongated slot.
Claim 2
Dependent Claim
94 words
A flat spray nozzle assembly comprising: a relatively thin spacer having a central through passage; an inlet plate stacked on one side of said spacer and having a plurality of spaced ports forming inlets to said passage; and an outlet plate stacked on the opposite side of said spacer and having a narrow elongated slot for discharge of fluid from said passage in a flat spray, said spaced ports lying on opposite sides of and being offset from said elongated slot, whereby the flow from said ports creates a turbulence along said elongated slot.
Claim 3
Dependent Claim
94 words
A flat spray nozzle assembly comprising: a relatively thin spacer having a central through passage; an inlet plate stacked on one side of said spacer and having a plurality of spaced ports forming inlets to said passage; and an outlet plate stacked on the opposite side of said spacer and having a narrow elongated slot for discharge of fluid from said passage in a flat spray, said spaced ports lying on opposite sides of and being offset from said elongated slot, whereby the flow from said ports creates a turbulence along said elongated slot.
Claim 4
Dependent Claim
94 words
A flat spray nozzle assembly comprising: a relatively thin spacer having a central through passage; an inlet plate stacked on one side of said spacer and having a plurality of spaced ports forming inlets to said passage; and an outlet plate stacked on the opposite side of said spacer and having a narrow elongated slot for discharge of fluid from said passage in a flat spray, said spaced ports lying on opposite sides of and being offset from said elongated slot, whereby the flow from said ports creates a turbulence along said elongated slot.
Claim 5
Dependent Claim
58 words
A nozzle assembly as in claim 1 wherein: said spacer is generally in the form of a sleeve having a relatively small axial dimension, the inner diameter of said sleeve forming said central through passage; and said inlet and outlet plates are generally circular plates having a diameter substantially equal to the outside diameter of said spacer sleeve.
Claim 6
Dependent Claim
13 words
A nozzle assembly as in claim 1 wherein said outlet plate is yieldable.
Claim 7
Dependent Claim
29 words
A nozzle assembly as in claim 1 having a pair of spaced ports positioned substantially along a line extending normal to and at the midpoint of said elongated slots.
Claim 8
Dependent Claim
64 words
A nozzle assembly as in claim 4 wherein: said spacer is in the form of a sleeve having a relatively small axial dimension, the inner diameter of said sleeve forming said central through passage; said inlet and outlet plates are generally circular having outside diameters substantially equal to the outside diameter of said spacer sleeve; said ports are spaced 180* apart from one another.
Claim 9
Dependent Claim
35 words
A nozzle assembly as in claim 5 wherein said spaced ports are formed by a pair of intersecting arcuate sides, one side of which conforms to the curvature of the inner diameter of said sleeve.
Claim 10
Dependent Claim
15 words
A flat spray nozzle assembly as in claim 6 wherein said outlet plate is yieldable.
