Abstract
An atomizing nozzle usable on a vaporizer or atomizer is provided, having a unified core and valve member and a diaphragm perforated by a narrow orifice. The unitary member is axially mobile and laterally guided in a chamber within the nozzle. Additionally, the unified member has, on its end remote from the orifice, a concave circular cup in which the edges of the cup are turned toward the orifice, and, on its end nearest to the orifice, a core portion which cooperates with the diaphragm to form a system of turbulent channels which supply the orifice.
Claims9
An atomizing nozzle comprising:
- a diaphragm member mounted on a housing so as to enclose a chamber therewith, said member being perforated by an axial orifice wherein said orifice is located at the distal end of said nozzle;
- and
- a unitary core and valve member comprising a valve portion and a core portion axially mobile and laterally guided within said chamber, said valve portion comprising a concave circular cup on an edge of said member remote from said orifice in which the edges of said cup engage an interior periphery of said chamber and are turned toward said orifice, and said core portion on an end of said member nearer to said orifice cooperating with said diaphragm to form a system of turbulent channels which supply said orifice.
