Claim Text:
1. A fog-cloud generating nozzle comprising: a nozzle head extending along a longitudinal axis and being generally cylindrical shaped, the nozzle head having a central body portion including a proximal end and a distal end; the nozzle head having a closed top member at the distal end and a threaded coupling member at the proximal end with a fluid passageway therein extending from the threaded coupling member to the closed top member, the fluid passageway having a fluid passageway cross-sectional area perpendicular to the longitudinal axis; the nozzle head having an internal central fluid cavity extending along the longitudinal axis in the central portion thereof; the nozzle head having a plurality of elongated ports distributed axially and circumferentially about the central body portion, the plurality of elongated ports configured to provide fluid communication between the internal central fluid cavity and a surface of the nozzle; the plurality of elongated ports being disposed in rows, each row having an acute pitch angle relative to the longitudinal axis so that during operation fluid exits the plurality of elongated ports toward the distal end; the acute pitch of each row of the plurality of elongated ports being greater than the acute pitch of the previous row; a nozzle base extending along the longitudinal axis, the nozzle base having a body member including a distal end and a proximal end, the fluid passageway extending therethrough; the nozzle base having a flange extending from the distal end, a first threaded coupling member is disposed at the flange and configured to mate with the threaded coupling member of the nozzle base; the nozzle base including a shoulder member at a base of the flange; the nozzle head including a second threaded coupling member disposed at the proximal end, the second threaded coupling configured to mate with a water source; an inner sleeve extending along the longitudinal axis and being generally cylindrical shaped, the inner sleeve having a main body sized for a bearing engagement between the closed top member of the nozzle head and the shoulder of the nozzle base, an annular chamber being formed between the inner sleeve and the nozzle head, the fluid passageway extending therethrough; and the inner sleeve including a plurality of orifices distributed axially and circumferentially about the main body, each of the plurality of orifices extending along a respective orifice axis, each orifice axis being at a positive acute pitch relative to the longitudinal axis so that during operation fluid exits the plurality of orifices from the fluid passageway into the annular chamber toward the distal end of the nozzle head, each orifice axis being at the positive acute radial angle with respect to corresponding radial lines extending in planes perpendicular to the longitudinal axis so that during operation fluid exits the plurality of orifices toward a rotational direction, thereby imparting a rotation to the inner sleeve.
