Abstract:
1. An apparatus, comprising: a housing including a bore for delivering pressurized fluid; a holder including an internal volume; a mating element that engages the holder and covers the internal volume thereof, the mating element including: (i) a bore in fluid communication with the bore of the housing for delivering the pressurized fluid into the internal volume of the holder, and (ii) an annular projection that extends into the internal volume of the holder; a nozzle including an outer contour and an internal, narrowing nozzle bore extending from a first end to a nozzle aperture at a second end through which an aerosol exits; an annular elastomeric part surrounding the outer contour of the nozzle and being disposed in the internal volume of the holder such that: (i) the first end of the nozzle is in fluid communication with, and receives the pressurized fluid from, the bore of the mating element, and (ii) both the first end of the nozzle and an adjacent end surface of the annular elastomeric part are spaced away from the bore of the mating element, thereby defining an unoccupied volume within the internal volume of the holder, and exposing the end surface of the annular elastomeric part to the pressurized fluid; and a union member bearing against the holder and engaging the housing such that: (i) the mating element is pressed toward the holder, and (ii) the annular projection of the mating element deforms the annular elastomeric part at the first end of the nozzle.
