Abstract
Nozzle apparatus and methods for treating workpieces are disclosed. An example apparatus includes a nozzle module and a first nozzle chamber disposed within the nozzle module. The first nozzle chamber has a first nozzle opening and is to deliver a relatively high pressure fluid to the first nozzle opening. The example apparatus also includes a second nozzle chamber disposed within the nozzle module and having a second nozzle opening, the second nozzle chamber to deliver a relatively low pressure fluid to a second nozzle opening. A first flow of the low pressure fluid at least partially contacts a second flow of the high pressure fluid. The second flow is directed onto a workpiece.
Claims29
An apparatus for treating workpieces comprising:
- a nozzle module comprising a module body having a first nozzle chamber, the first nozzle chamber comprising a first nozzle mouth through which an axis extends, the first nozzle mouth having a first nozzle opening, the first nozzle chamber extending in a longitudinal direction along the axis, the first nozzle opening to generate a high-pressure liquid jet in the direction of the axis onto a workpiece, wherein the module body comprises a second nozzle chamber extending in the longitudinal direction;
- a first device to deliver liquid under relatively high pressure into the first nozzle chamber to generate a high-pressure liquid jet;
- and
- a second device to deliver liquid or gaseous fluid under relatively low pressure into a second nozzle chamber to generate a low-pressure fluid jet, wherein the second nozzle chamber comprises a second nozzle mouth to face the workpiece, the second nozzle mouth having a second nozzle opening to generate the low-pressure fluid jet flowing at least partially along and contacting the high-pressure liquid jet.
A method for treating a workpiece comprising:
- generating at least a first liquid jet at a relatively high pressure emerging from a first nozzle opening of a first nozzle chamber and directed onto the workpiece;
- and
- generating at least a first fluid jet at a relatively low pressure emerging from a second nozzle opening of a second nozzle chamber and directed onto the workpiece, wherein the first fluid jet flows along and at least partially contacts the first liquid jet.
An apparatus comprising:
- a nozzle module;
- a first nozzle chamber disposed within the nozzle module and having a first nozzle opening, the first nozzle chamber to deliver a relatively high pressure fluid to the first nozzle opening;
- and
- a second nozzle chamber disposed within the nozzle module and having a second nozzle opening, the second nozzle chamber to deliver a relatively low pressure fluid to a second nozzle opening,
- wherein a first flow of the low pressure fluid at least partially contacts a second flow of the high pressure fluid, the second flow directed onto a workpiece.
