Abstract
Abstract A device for the fine, homogeneous pulverization of one fluid by another. The device comprises an intake pipe carrying the driving fluid, a tube carrying the fluid to be driven which is introduced into the driving fluid, and an olive-shaped mass arranged at the outlet of the intake pipe and coaxial therewith. The forward end of the olive-shaped mass extends beyond the plane of the outlet orifice of the intake pipe. The plane including the largest cross-section of the mass substantially coincides with the plane of the outlet orifice of the intake pipe. An annular passage is formed between the olive-shaped mass and the interior wall of the intake pipe. The pressure of the fluid is relatively low so that at least the portion in the vicinity of the olive-shaped mass flows parallel to the axis of the pipe. The tube is connected by a slit or radial channels to discharge the fluid to be driven at one or more points on the outer surface of the olive-shaped mass. A ring of blades inclined at 15* to the common axis and parallel to one another may be provided in the intake pipe. A further conduit may be provided about the intake pipe which defines the annular passage.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
171 words
A device for fine, homogeneous spraying of a driven fluid by a driving fluid, comprising an intake pipe for the driving fluid and a second pipe for introducing second fluid to be driven into the driving fluid, a generally olive-shaped mass arranged at the outlet orifice of said intake pipe and coaxial therewith, the tip of the olive-shaped mass being disposed beyond the outlet orifice of the intake pipe, the plane of the largest cross-section of the olive-shaped mass substantially coinciding with the plane of the outlet orifice of said intake pipe, an annular passage being formed between the olive-shaped mass and the interior wall of said intake pipe, said second pipe carrying the driven fluid to the interior of said mass at a relatively low pressure so that at least the portion of fluid in the vicinity of the olive-shaped mass flows parallel to the axis of the first pipe, and means for discharging the second fluid at at least one point on the outer surface of the olive-shaped mass.
Claim 2
Independent Claim
171 words
A device for fine, homogeneous spraying of a driven fluid by a driving fluid, comprising an intake pipe for the driving fluid and a second pipe for introducing second fluid to be driven into the driving fluid, a generally olive-shaped mass arranged at the outlet orifice of said intake pipe and coaxial therewith, the tip of the olive-shaped mass being disposed beyond the outlet orifice of the intake pipe, the plane of the largest cross-section of the olive-shaped mass substantially coinciding with the plane of the outlet orifice of said intake pipe, an annular passage being formed between the olive-shaped mass and the interior wall of said intake pipe, said second pipe carrying the driven fluid to the interior of said mass at a relatively low pressure so that at least the portion of fluid in the vicinity of the olive-shaped mass flows parallel to the axis of the first pipe, and means for discharging the second fluid at at least one point on the outer surface of the olive-shaped mass.
Claim 3
Dependent Claim
81 words
A device according to claim 1, wherein the intake pipe is provided along its interior wall with at least one ring of blades parallel to one another and inclined at approximately 15* relative to the axis common to the olive-shaped mass and the intake pipe, the radial dimension of said passage being such that the driving fluid portion also flows parallel in the vicinity of the olive-shaped mass, the rest of this fluid undergoing a helical rotary movement about said axis.
Claim 4
Dependent Claim
37 words
A device according to claim 2, wherein the inclined blades are formed as guide elements with wing-shaped profiles fed from the exterior with fluid to be sprayed and discharging this fluid into the annular passage through openings.
Claim 5
Dependent Claim
21 words
A device according to claim 2, wherein said ring is mounted in the vicinity of the outlet of said intake pipe.
Claim 6
Dependent Claim
17 words
A device according to claim 4, wherein a portion of said blades are outside the intake pipe.
Claim 7
Dependent Claim
49 words
A device according to claim 1, further comprising a conduit coaxial with the intake pipe and the olive-shaped mass and disposed about the intake pipe and defining said annular passage fed by the driving fluid, said conduit being provided with blades inclined at about 15* to the common axis.
Claim 8
Dependent Claim
36 words
A device according to claim 1, wherein the olive-shaped mass is solid and has a longitudinal axial channel opening to the surrounding environment at said tip and connected at its other end to said second pipe.
Claim 9
Dependent Claim
26 words
A device according to claim 1, wherein the tip of the olive-shaped mass is truncated to form a cup-shaped flat-bottomed portion with outwardly flaring side walls.
Claim 10
Dependent Claim
95 words
A device according to claim 1, wherein the olive-shaped mass is formed in two parts, a first part forming a base having a threaded axial bore screwed onto said second pipe, said second pipe having a plurality of radial orifices, and a second part formed as an olive-tip-shaped body with a threaded bore screwed onto said pipe, the adjacent portions of said parts having peripheral areas substantially parallel to each other forming a slit opening therebetween at the plane of the largest cross-section of the olive-shaped mass effectively formed by said first and second parts.
Claim 11
Dependent Claim
13 words
A device according to claim 1, wherein the relatively low pressure is negative.
Claim 12
Dependent Claim
13 words
A device according to claim 1, wherein the relatively low pressure is positive.
Claim 13
Dependent Claim
14 words
A device according to claim 1, wherein the relatively low pressure is substantially nil.
