Abstract

A delivery nozzle for aerosol and solvent includes a nozzle body defining an aerosol passage and a solvent passage therethrough. The aerosol and solvent passages each extend from an inlet end of the nozzle body to an outlet end thereof. The nozzle body can include a solid, unitary structure with the aerosol and solvent passages both defined through the solid, unitary structure. The inlet end of the nozzle body can include a mounting flange configured to mount the nozzle body in a device for delivering aerosol through the aerosol passage and for delivering solvent through the solvent passage. The solvent passage can define a smaller cross-sectional flow area than that of the aerosol passage.

First claim

What is claimed is:

1. A delivery nozzle for aerosol and solvent comprising:
a nozzle body defining an aerosol passage and a solvent passage therethrough, wherein the aerosol and solvent passages each extend from an inlet end of the nozzle body to an outlet end thereof, wherein the inlet end of the nozzle body includes a mounting flange configured to mount the nozzle body in a device for delivering aerosol through the aerosol passage and for delivering solvent through the solvent passage, wherein inlets of the aerosol passage and solvent passage are both defined in the mounting flange and face away from the outlet end, and wherein the aerosol and solvent passages each include an outlet in the outlet end of the nozzle body, wherein the outlets face away from the inlet end and in an opposite direction from that of the inlets.

2. The delivery nozzle as recited in claim 1 , wherein the nozzle body includes a solid, unitary structure with the aerosol and solvent passages both defined through the solid, unitary structure.

3. The delivery nozzle as recited in claim 1 , the solvent passage defines a smaller cross-sectional flow area than that of the aerosol passage.

4. The delivery nozzle as recited in claim 1 , wherein the nozzle body includes a chemically inert material.

5. The delivery nozzle as recited in claim 1 , wherein the nozzle body includes a material resistant to low PH solvent passing therethrough.

6. The delivery nozzle as recited in claim 1 , wherein the nozzle body includes at least one of quartz, steel, plastic, polytetrafluoroethylene, ceramic, or silicon.

7. The delivery nozzle as recited in claim 1 , wherein the solvent passage is a first solvent passage, wherein the nozzle body defines at least one additional solvent passage extending from the inlet end of the nozzle body to an outlet end thereof.

8. The delivery nozzle as recited in claim 1 , wherein the aerosol passage is a first aerosol passage, wherein the nozzle body defines at least one additional aerosol passage extending from the inlet end of the nozzle body to an outlet end thereof.

9. The delivery nozzle as recited in claim 1 , wherein at least one of the aerosol passage and the solvent passage defines a tortuous path.

10. A delivery nozzle for aerosol and solvent comprising:
a nozzle body defining an aerosol passage and a solvent passage therethrough, wherein the aerosol and solvent passages each extend from an inlet end of the nozzle body to an outlet end thereof, wherein the inlet end of the nozzle body includes a mounting flange configured to mount the nozzle body in a device for delivering aerosol through the aerosol passage and for delivering solvent through the solvent passage, wherein inlets of the aerosol passage and solvent passage are both defined in the mounting flange, wherein each of the aerosol and solvent passages includes a respective inlet defined in the inlet end of the nozzle body, wherein each of the aerosol and solvent passages includes a respective outlet defined in the outlet end of the nozzle body, and wherein the outlets of the aerosol and solvent passages are closer together than are the inlets thereof to direct solvent and aerosol issued from the nozzle body to meet outside the nozzle body.

11. A delivery nozzle for aerosol and solvent comprising:
a nozzle body defining an aerosol passage and a solvent passage therethrough, wherein the aerosol and solvent passages each extend from an inlet end of the nozzle body to an outlet end thereof, wherein the inlet end of the nozzle body includes a mounting flange configured to mount the nozzle body in a device for delivering aerosol through the aerosol passage and for delivering solvent through the solvent passage, wherein inlets of the aerosol passage and solvent passage are both defined in the mounting flange, wherein each of the aerosol and solvent passages includes a respective inlet defined in the inlet end of the nozzle body, wherein the inlet of the solvent passage includes a seal for sealing pressurized passage of solvent into the solvent passage.

12. A delivery nozzle for aerosol and solvent comprising:
a nozzle body defining an aerosol passage and a solvent passage therethrough, wherein the aerosol and solvent passages each extend from an inlet end of the nozzle body to an outlet end thereof, wherein the inlet end of the nozzle body includes a mounting flange configured to mount the nozzle body in a device for delivering aerosol through the aerosol passage and for delivering solvent through the solvent passage, wherein inlets of the aerosol passage and solvent passage are both defined in the mounting flange, wherein at least one of:
the aerosol passage is lined with an electrically conductive layer,
the aerosol passage is lined with a gold coating layer, and/or
a capillary is disposed within the solvent passage.
