A nozzle assembly for use in abrasive cutting, comprising: an upper body which has an abrasive inlet and abrasive outlet formed in said upper body, and an abrasive conduit joining said abrasive inlet to said abrasive outlet within said upper body; a fluid inlet formed in said upper body; a plurality of fluid outlets formed in said upper body surrounding said abrasive outlet; a manifold formed in said upper body in fluid communication with said fluid inlet and all of said fluid outlets; a lower body having a mixing chamber formed therein; a plurality of jewel-mount orifices formed in said lower body in fluid communication with said mixing chamber, each of said jewel-mount orifices being associated with and in fluid communication with one of said fluid outlets, and an abrasive orifice formed in said lower body in fluid communication with said abrasive outlet and said mixing chamber; a plurality of jewels, each jewel associated with and mounted in one of said jewel-mount orifices, each of said jewels having a stream-forming aperture formed therethrough in fluid communication with its associated jewel-mount orifice; and nozzle exit means mounted in said lower body, said exit means including an exit passageway in fluid communication with said mixing chamber; wherein said upper and lower bodies are separate structures, said nozzle assembly further including locking means associated with said upper and lower bodies to hold said upper and lower bodies in close contact; and said upper body is substantially cylindrically shaped and has a lower mating surface and said lower body is substantially cylindrically shaped and has an upper mating surface congruent to said lower mating surface of said upper body, said abrasive outlet and said fluid outlets being formed in said lower mating surface and said abrasive orifice and said jewel-mount orifices being formed in said upper mating surface.
Claim 2
Dependent Claim

A nozzle assembly for use in abrasive cutting, comprising: an upper body which has an abrasive inlet and abrasive outlet formed in said upper body, and an abrasive conduit joining said abrasive inlet to said abrasive outlet within said upper body; a fluid inlet formed in said upper body; a plurality of fluid outlets formed in said upper body surrounding said abrasive outlet; a manifold formed in said upper body in fluid communication with said fluid inlet and all of said fluid outlets; a lower body having a mixing chamber formed therein; a plurality of jewel-mount orifices formed in said lower body in fluid communication with said mixing chamber, each of said jewel-mount orifices being associated with and in fluid communication with one of said fluid outlets, and an abrasive orifice formed in said lower body in fluid communication with said abrasive outlet and said mixing chamber; a plurality of jewels, each jewel associated with and mounted in one of said jewel-mount orifices, each of said jewels having a stream-forming aperture formed therethrough in fluid communication with its associated jewel-mount orifice; and nozzle exit means mounted in said lower body, said exit means including an exit passageway in fluid communication with said mixing chamber; wherein said upper and lower bodies are separate structures, said nozzle assembly further including locking means associated with said upper and lower bodies to hold said upper and lower bodies in close contact; and said upper body is substantially cylindrically shaped and has a lower mating surface and said lower body is substantially cylindrically shaped and has an upper mating surface congruent to said lower mating surface of said upper body, said abrasive outlet and said fluid outlets being formed in said lower mating surface and said abrasive orifice and said jewel-mount orifices being formed in said upper mating surface.
Claim 3
Dependent Claim
52 words
The abrasive nozzle of claim 1 wherein said locking means includes a locking ring threadably engaging said upper body, said locking ring having a shoulder formed thereon that engages a cooperative shoulder formed on said lower body to exert a compressive force in the axial direction on said upper and lower bodies.
Claim 4
Dependent Claim
72 words
The abrasive nozzle of claim 2, further including: a first locking pin inserted into said upper mating surface and engaging a hole in said upper mating surface and a second locking pin radially spaced from said first locking pin mounted in said upper mating surface and engaging a hole formed in said lower mating surface, said locking pin reacting any torque exerted on said upper and lower bodies by said locking ring.
