Abstract

A laminated nozzle assembly is provided. The laminated nozzle includes a first end plate having a first fluid inlet and a second fluid inlet, a second end plate, a plurality of nozzle plates positioned and clamped between the first end plate and the second end plate, a first fluid conduit in fluid communication with the first fluid inlet formed in one or more of the nozzle plates, a second fluid conduit in fluid communication with the second fluid inlet formed in one or more of the nozzle plates, a first orifice in fluid communication with the first fluid conduit formed in one of the nozzle plates, and a second orifice in fluid communication with the second fluid conduit formed in the same nozzle plate as the first orifice. The laminated nozzle assembly minimizes the number of nozzle plates and includes no more than eight, and preferably no more than five nozzle plates.

First claim

What is claimed is:

1. A laminated nozzle assembly comprising:
a first end plate having a first fluid inlet and a second fluid inlet;
a second end plate;
a plurality of nozzle plates positioned and clamped between the first end plate and the second end plate;
a first fluid conduit in fluid communication with the first fluid inlet formed in one or more of the nozzle plates;
a second fluid conduit in fluid communication with the second fluid inlet formed in one or more of the nozzle plates;
a first orifice formed in one of the nozzle plates of the plurality of nozzle plates between the first and second end plates and disposed in fluid communication with the first fluid conduit for discharging a first fluid from the nozzle assembly, wherein the first orifice is configured to receive the first fluid from the first fluid conduit at a first side of the one nozzle plate; and
a second orifice formed in the same one nozzle plate of the plurality of nozzle plates between the first and second end plates as the first orifice and disposed in fluid communication with the second fluid conduit for discharging a second fluid from the nozzle assembly, wherein the second orifice is configured to receive the second fluid from the second fluid conduit at a second side opposite the first side, of the one nozzle plate,
wherein the first and second orifices are coplanar.

2. The laminated nozzle assembly of claim 1 , wherein the plurality of nozzle plates includes less than eight nozzle plates.

3. The laminated nozzle assembly of claim 1 , wherein the plurality of nozzle plates includes no more than five nozzle plates.

4. The laminated nozzle assembly of claim 3 , wherein the nozzle assembly includes three nozzle plates.

5. The laminated nozzle assembly of claim 1 , including a plurality of first and second orifices.

6. The laminated nozzle assembly of claim 5 , wherein the plurality of first and second orifices are coplanar.

7. The laminated nozzle assembly of claim 1 , wherein at least some of the plurality of nozzle plates have a thickness of about 0.005 to about 0.500 mm.

8. The laminated nozzle assembly of claim 1 , including one or both of first and second fluid plena and wherein the first and/or second fluid plena are in the first and/or second end plates, respectively.

9. The laminated nozzle assembly of claim 8 , wherein the nozzle assembly includes three nozzle plates.

10. A laminated nozzle assembly comprising:
a first end plate having a first fluid inlet and a second fluid inlet;
a second end plate;
a plurality of nozzle plates positioned and clamped between the first end plate and the second end plate by way of one or more fasteners extending through the first end plate, second end plate and plurality of nozzle plates;
a first fluid conduit in fluid communication with the first fluid inlet formed in one or more of the nozzle plates;
a second fluid conduit in fluid communication with the second fluid inlet formed in one or more of the nozzle plates;
a first orifice formed in one of the nozzle plates of the plurality of nozzle plates in fluid communication with the first fluid conduit; and
a second orifice formed in the same one nozzle plate of the plurality of nozzle plates as the first orifice and disposed in fluid communication with the second fluid conduit,
wherein the first and second orifices are coplanar,
wherein the plurality of nozzle plates includes no more than five nozzle plates, and
wherein the one nozzle plate having the first orifice and second orifice formed therein is a centrally positioned nozzle plate disposed between other nozzle plates of the plurality of nozzle plates.
