Abstract
A spray nozzle comprising a housing including a primary passage defining a primary axis, a series of secondary passages configured to provide swirl to a fluid passing therethrough circumferentially positioned around the housing, a series of standoffs circumferentially spread around an outer surface of the housing and located downstream along the primary axis of the series of swirling passages, wherein each of the swirling passages corresponds to a respective standoff of the series of standoffs, in order to control the swirl of the fluid.
Claims16
A spray nozzle comprising:
- a housing including a primary passage defining a primary axis;
- a series of secondary passages configured to provide swirl to a fluid passing therethrough, circumferentially positioned around the housing;
- and
- a series of standoffs circumferentially spread around an outer surface of the housing and located downstream along the primary axis of the series of swirling passages, wherein each of the swirling passages corresponds to a respective standoff of the series of standoffs, in order to control the swirl of the fluid.
A nozzle assembly comprising:
- a housing including a primary passage defining a primary axis;
- a series of secondary passages configured to provide swirl to a fluid passing therethrough, circumferentially positioned around the housing;
- a series of standoffs circumferentially spread around an outer surface of the housing and located downstream along the primary axis of the series of swirling passages, wherein each of the swirling passages corresponds to a respective standoff of the series of standoffs, in order to control the swirl of the fluid;
- and
- an outer sleeve covering the nozzle.
The nozzle assembly of claim 12, wherein a top surface of each of the standoff is flush against an inner surface of the outer sleeve.
A method of spraying a fluid comprising the steps of:
- feeding a fluid stream through a primary passage of a nozzle along a primary axis;
- producing a swirling fluid stream through a series of secondary passages along a secondary axis, at a non-parallel angle to the primary axis;
- and
- reducing the swirl of the fluid by impinging the fluid against a series of standoffs downstream of the secondary passages.
The method of claim 15, wherein the spray includes at least an 80 degree angle.
