Abstract
The water-saving nozzle has an outer housing that includes an outer vortex screw in operative engagement with an inner housing that is disposed inside the outer housing. The vortex screw has helical threads. The inner housing has an inner vortex screw with outside helical threads. When water passes through the outer and inner vortex screws the water is rotated before the water passes into the vortex chambers of the inner and outer housings. The water discharged from the outer housing forms an outer dome shape and the water discharged from the inner housing forms an inner dome shape inside the outer dome shape.
Claims9
A water-saving nozzle, comprising:
- an outer housing having an inlet opening and chamber and a first discharge opening defined therein;
- an outer vortex screw in operative engagement with an inner wall of the outer housing, the outer vortex screw having a central chamber defined therein,
- an inner housing in operative engagement with the outer vortex screw inside the central chamber, the outer vortex screw having outside helical threads facing the inner wall;
- the outer housing having an outer vortex chamber defined therein below the vortex screw;
- the outer housing having the first discharge opening defined at a bottom portion thereof, the inlet opening being in fluid communication with the chamber of the outer housing, the helical threads, the vortex chamber and the first discharge opening so that water is flowable through the nozzle and dischargeable through the first discharge opening in an outer dome shape;
- the inner housing having an inlet opening defined therein;
- the inner housing having an inner vortex screw in operative engagement with an inside wall, the inner vortex screw having outside helical threads facing the inside wall;
- and
- the inner housing having an inner vortex chamber defined therein below the vortex screw;
- the inner housing having a second discharge opening defined therein, the inlet opening being in fluid communication with the central chamber, the helical threads, the inner vortex chamber and the second discharge opening so that water is flowable through the nozzle and dischargeable through the second discharge opening in an inner dome shape inside the outer dome shape.
