Patent ID: 7389941

Claim:
A nozzle device for mixing and directing a composite fluid comprising: a cylinder having a proximal end and a distal end, the cylinder containing an axial bore extending from the proximal end to the distal end; an annular wall extending radially from the cylinder; an annulus extending from the annular wall; an annular chamber at least partially open to the atmosphere, the annular chamber defined by the cylinder, the annular wall and the annulus; a portal positioned within the cylinder fluidly communicating the bore with the annular chamber; an annular collar connected to the cylinder and at least partially positionable within the annular chamber; a frusto-conical nose section extending from the annular collar toward the distal end of the bore; a first tube disposable within the bore for transporting a primary fluid, the first tube terminating proximate the distal end of the bore; and a second tube positionable within the bore for transporting a secondary fluid, the second tube having an open end terminating proximate the portal, wherein a propellant fluid flowing within the bore about the first and second tubes directs the secondary fluid exiting the second tube into the annular chamber through the portal, wherein the propellant fluid and the secondary fluid pass about the annular collar being directed by the annular chamber along the frusto-conical nose section toward the distal end of the bore, wherein the primary fluid exiting the distal end of the bore admixes with the propellant fluid and the secondary fluid to form the composite fluid outside the nozzle device.
