Abstract
A sprinkler nozzle having a nozzle housing with an inlet for liquid and having a longitudinally extending axis. The nozzle housing, opposite the inlet, is delimited by a surface of revolution with nozzle outlet openings arranged around the axis. In the flow direction opposite the nozzle outlet openings, respective impact faces are arranged for reflecting the liquid that flows out through the nozzle outlet openings. The impact faces are constituted by the ends of respective threads that are secured to the nozzle housing, whereby the impact faces are able to reflect water that flows out of the respective nozzle outlet openings.
Claims20
A sprinkler nozzle comprising a nozzle housing with an inlet for liquid and with a longitudinally extending axis, said nozzle housing, opposite the inlet, being delimited by a surface of revolution with nozzle outlet openings arranged around the axis, a plurality of impact faces respectively arranged opposite and proximate to mouths of the nozzle outlet openings so as to reflect the liquid that flows out through the nozzle outlet openings back toward said nozzle outlet openings to create small droplets of liquid said impact faces being constituted by the ends of respective threads that are secured to the nozzle housing.
A sprinkler nozzle comprising a nozzle housing with an inlet for liquid and a longitudinally extending axis, said nozzle housing, opposite the inlet, having a plurality of nozzle outlet openings arranged around the axis, a plurality of impact faces respectively located centrally in front of said nozzle outlet openings to reflect at least a portion of the liquid that flows out through the nozzle outlet openings back toward said nozzle outlet openings to create small droplets of liquid, each of said impact faces being constituted by the end of a respective thread that is secured to the nozzle housing.
A sprinkler nozzle comprising a nozzle housing with an inlet for liquid and a longitudinally extending axis, said nozzle housing, opposite the inlet, being delimited by a surface of revolution with a plurality of nozzle outlet openings arranged around the axis and configured in said surface of revolution such that the outflow of liquid extends in a direction relative to the longitudinal axis of the nozzle housing of 45°, +/−10°, a plurality of impact faces respectively positioned opposite the mouths of the nozzle outlet openings so as to reflect at least a portion of the liquid that flows out through the nozzle outlet openings back toward said nozzle outlet openings to create small droplets of liquid through said reflection and resulting collision of liquid particles.
