Modular dual vector fluid spray nozzles
View Patent ↗Various embodiments of modular dual vector fluid spray nozzles are disclosed. Embodiments of the nozzles are characterized by specially shaped fluid channels, impingement surfaces and exit orifices used to generate atomized mists of fluid under pressure. Embodiments of the nozzles are generally characterized by composite fluid spray density patterns having horizontal and vertical components, i.e., dual vector in nature. The nozzles disclosed are modular and may be easily installed or removed from a given fluid spray system, nozzle head, or fixture as dictated by any given application.
1. A fluid nozzle, comprising:
an integral cylindrical housing including a fluid channel having a fluid channel axis disposed coaxially through the cylindrical housing from a fluid intake port on a proximate end to a slotted orifice at a distal end, the slotted orifice having parallel opposed edges at the distal end, an exit plane passing between, and parallel to, the parallel opposed edges;
the fluid channel further comprising a plurality of cylindrical sub-channels, each of the plurality of sub-channels having a sub-channel axis parallel to the fluid channel axis, each sub-channel axis beginning from the intake port and passing through the slotted orifice along the exit plane;
each of the cylindrical sub-channels formed by a bore hole beginning from the proximate end of the cylindrical housing and ending in opposed hemispherical impingement surfaces at the slotted orifice; and
wherein a cross-section of the intake port at the proximate end comprises a plurality of circular openings, each of the circular openings intersecting an adjacent circular opening and each of the plurality of circular openings corresponds to one of the plurality of channels.
2. The fluid nozzle according to claim 1 , wherein the integral cylindrical housing further comprises external threading along an outer surface adjacent the proximate end, the threading configured for mounting the fluid nozzle to a fluid spray system head.
3. The fluid nozzle according to claim 2 , wherein the integral cylindrical housing further comprises a circumferential groove formed within the housing at a location between the proximate end and the distal end, the groove adapted to receive an O-ring for sealing the threading.
4. The fluid nozzle according to claim 1 , wherein the plurality of sub-channels comprises two sub-channels.
5. The fluid nozzle according to claim 1 , wherein each of the plurality of circular openings surrounding a portion of a volume formed by sweeping the slotted orifice along the fluid channel axis from the distal end to the proximate end.
6. The fluid nozzle according to claim 5 , wherein a composite spray pattern generated by pressurized fluid entering the intake port and exiting the orifice of the fluid nozzle forms a plume of fluid vapor having a horizontally oriented main plume exiting radially along a plane formed by the slotted orifice and the fluid channel axis, and having a vertically oriented plume exiting the slotted orifice in a plane oriented perpendicularly relative to the main plume.
7. The fluid nozzle according to claim 6 , wherein the vertically oriented plume is formed by the intersection of adjacent sub-channels.
8. The fluid nozzle according to claim 6 , wherein each of the plumes, vertical or horizontal, comprises a peak fluid vapor density along an exit trajectory plane.
