In a spray nozzle (), a carrier () defines a spray aperture (), a groove () surrounding the spray aperture for receiving an o-ring (), a first locating bore () for slidably receiving an orifice plate () seated against the o-ring () and for aligning the orifice plate with the spray aperture, and a second locating bore () for slidably receiving a swirl unit and aligning the swirl unit () with the orifice plate and spray aperture. The swirl unit () defines on its peripheral surface a recessed flat () forming a fluid passageway between the swirl unit and carrier. The swirl unit () includes a swirl chamber () defined by a curvilinear surface () formed within the swirl unit, and an inlet port () formed in fluid communication between the swirl chamber and fluid passageway. The nozzle body () is threadedly received within the carrier () behind the swirl unit () to axially press the swirl unit, and in turn press the orifice plate () against the adjacent surface of the carrier.

In a spray nozzle (,), a carrier (,) defines a spray aperture (,), a groove (,) surrounding the spray aperture for receiving an o-ring (,), a first locating bore (,) for slidably receiving an orifice plate (,) seated against the o-ring (,) and for aligning the orifice plate with the spray aperture, and a second locating bore (,) for slidably receiving a swirl unit and aligning the swirl unit (,) with the orifice plate and spray aperture. The swirl unit (,) defines on its peripheral surface a recessed flat (,) forming a fluid passageway between the swirl unit and carrier. The swirl unit (,) includes a swirl chamber (,) defined by a curvilinear surface (,) formed within the swirl unit, and an inlet port (,) formed in fluid communication between the swirl chamber and fluid passageway.

In a spray nozzle, a carrier defines a spray aperture, a groove surrounding the spray aperture for receiving an o-ring, a first locating bore for slidably receiving an orifice plate seated against the o-ring and for aligning the orifice plate with the spray aperture, and a second locating bore for slidably receiving a swirl unit and aligning the swirl unit with the orifice plate and spray aperture. A pair of retaining lugs project inwardly from the carrier a predetermined distance for engaging the upstream end of the swirl unit to thereby retain the swirl unit and orifice plate within the carrier. The swirl unit defines on its peripheral surface a recessed flat which is aligned with the retaining lugs to thereby clear the lugs upon inserting the swirl unit into the carrier. An elongated slot is formed on the upstream end of the swirl unit for receiving a screw driver.
