Abstract

Abstract A solid-cone jet nozzle for spraying liquids has a cylindrical turbulence chamber, a liquid feed bore that tangentially enters the chamber, a flaring discharge opening that forms an axial extension of the chamber, and recesses and elevations made in the bottom of the chamber. The liquid exits the discharge opening in a direction which is perpendicular to the liquid feed bore. The recesses and elevations control the liquid flow.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 128 words
A solid-cone jet nozzle, comprising: a. an open ended cylindrical housing having a central longitudinal axis and including a turbulence chamber therein; b. said chamber having an inner annular wall; c. inlet means for said chamber, said inlet means substantially tangential to said chamber; d. a turbulence chamber bottom spaced from said inlet means and closing one end of said housing and having a number of sized shaped spaced elevations axially extending therefrom into said chamber, at least a portion of said number spaced from said inner annular wall; and, e. flaring nozzle means co-axially positioned on said housing opposite said bottom whereby fluid entering said chamber is rotationally oriented and interacts with said elevations to exit said nozzle with a solid-cone pattern having a substantially axial orientation.
Claim 2
Dependent Claim 128 words
A solid-cone jet nozzle, comprising: a. an open ended cylindrical housing having a central longitudinal axis and including a turbulence chamber therein; b. said chamber having an inner annular wall; c. inlet means for said chamber, said inlet means substantially tangential to said chamber; d. a turbulence chamber bottom spaced from said inlet means and closing one end of said housing and having a number of sized shaped spaced elevations axially extending therefrom into said chamber, at least a portion of said number spaced from said inner annular wall; and, e. flaring nozzle means co-axially positioned on said housing opposite said bottom whereby fluid entering said chamber is rotationally oriented and interacts with said elevations to exit said nozzle with a solid-cone pattern having a substantially axial orientation.
Claim 3
Dependent Claim 140 words
A solid-cone jet nozzle, comprising: a. an open ended cylindrical housing having a central longitudinal axis and including a turbulence chamber therein; b. said chamber having an inner annular wall; c. inlet means for said chamber, said inlet means substantially tangential to said chamber; d. a turbulence chamber bottom spaced from said inlet means and closing one end of said housing; e. a number of elevations associated with said bottom and axially extending therefrom into said chamber, said elevations having substantially arcuate axially extending external side surfaces only and said elevations tapering from said inner annular wall toward said central axis; and, f. flaring nozzle means co-axially positioned on said housing opposite said bottom whereby fluid entering said chamber is rotationally oriented and interacts with said elevations to exit said nozzle with a solid-cone pattern having a substantially axial orientation.
Claim 4
Dependent Claim 140 words
A solid-cone jet nozzle, comprising: a. an open ended cylindrical housing having a central longitudinal axis and including a turbulence chamber therein; b. said chamber having an inner annular wall; c. inlet means for said chamber, said inlet means substantially tangential to said chamber; d. a turbulence chamber bottom spaced from said inlet means and closing one end of said housing; e. a number of elevations associated with said bottom and axially extending therefrom into said chamber, said elevations having substantially arcuate axially extending external side surfaces only and said elevations tapering from said inner annular wall toward said central axis; and, f. flaring nozzle means co-axially positioned on said housing opposite said bottom whereby fluid entering said chamber is rotationally oriented and interacts with said elevations to exit said nozzle with a solid-cone pattern having a substantially axial orientation.
Claim 5
Dependent Claim 21 words
A solid-cone jet nozzle as described in claim 1, wherein: a. said elevations are arranged in a number of spaced rows.
Claim 6
Dependent Claim 20 words
A solid-cone jet nozzle as described in claim 1, wherein: a. said elevations are arranged in a regular geometric array.
Claim 7
Dependent Claim 17 words
A solid-cone jet nozzle as described in claim 1, wherein: a. said elevations include substantially rectangular polyhedrons.
Claim 8
Dependent Claim 18 words
A solid-cone jet nozzle as described in claim 1, wherein: a. said elevations include substantially pyramidal shaped structures.
Claim 9
Dependent Claim 18 words
A solid-cone jet nozzle as described in claim 1, wherein: a. said elevations include substantially conically shaped structures.
Claim 10
Dependent Claim 61 words
A solid-cone jet nozzle as described in claim 2, wherein: a. said elevations define a number of partially circular chambers located between adjacent elevations; b. said circular chambers are positioned equi-angularly around said bottom; and, c. each of said substantially circular chambers has a central axis and each of said central axes is positioned an equal distance from said chamber axis.
Claim 11
Dependent Claim 31 words
A solid-cone jet nozzle as described in claim 8, wherein: a. each of said central axes is positioned a distance from said chamber axis which does not exceed said bottom radius.
Claim 12
Dependent Claim 24 words
A solid-cone jet nozzles described in claim 8, wherein: a. a substantially circular chamber co-axial with said bottom is centrally positioned between said elevations.
Claim 13
Dependent Claim 21 words
A solid-cone jet nozzle as described in claim 1 or 2, wherein: a. said bottom is detachably mounted to said housing.
Claim 14
Dependent Claim 26 words
A solid-cone jet nozzle as described in claim 11, wherein: a. said bottom includes a radially extending flange for detachably fastening said bottom to said housing.
Claim 15
Dependent Claim 57 words
A solid-cone jet nozzle as described in claim 11, wherein: a. said bottom includes an upper surface and a lower surface; b. said elevations are associated with said lower surface; and, c. either of said surfaces may be positioned so as to be adjacent said housing whereby one of said surfaces is therefore not adjacent said housing.
Claim 16
Dependent Claim 76 words
A solid-cone jet nozzle as described in claim 12, wherein: a. said flange is positioned between an upper surface and a lower surface of said bottom; b. said flange diameter at least equals said housing diameter; and, c. said upper surface and said lower surface have equal diameters and said diameters are less than said turbulence chamber diameter whereby one of said surfaces may be positioned in said chamber for centering said flange on said housing.
Claim 17
Dependent Claim 32 words
A solid-cone jet nozzle as described in claim 13, wherein: a. said upper surface is substantially flat; and, b. positioning of said upper surface adjacent said housing produces a hollow cone pattern.
Claim 18
Dependent Claim 36 words
A solid-cone jet nozzle as described in claim 1 or 2, wherein: a. said bottom is spaced a distance from said inlet means; and, b. said distance is substantially equal to one-tenth said inlet means diameter.
