Aeration device
View Patent ↗Aeration devices for generating bubbles in a flow of water are disclosed including an aerator body ( 1 ), a diverter ( 3 ) including orifices ( 31 ) for receiving the flow of water, each of the orifices ( 31 ) including a decreasing pore size in the direction from the upper portion of the diverter ( 3 b ) towards the lower portion of the diverter ( 3 a ), and a lower body portion ( 2 ) including a water chamber ( 2 a ) for receiving and aerating the flow of water from the orifices ( 31 ) in the diverter ( 3 ). Aeration devices are also disclosed including a pressure compensator ( 6 ) mounted on the upper portion of the diverter ( 3 b ) for regulation of the maximum flow of water therethrough, the aerator body ( 1 ) including a ball joint opening ( 11 ) and a ball joint ( 12 ) mounted within the ball joint opening ( 11 ), the ball joint ( 12 ) comprising plastic and the upper ball joint ( 13 ) comprising metal.
1. An aerator for generating bubbles in a flow of water comprising an aerator body, a diverter having an upper portion and a lower portion attached to said aerator body, said diverter including a plurality of orifices for receiving said flow of water, each of said plurality of orifices including a decreasing pore size in a direction from said upper portion of said diverter towards said lower portion of said diverter, and a lower body portion including a water chamber having an inner surface and an outer surface for receiving and aerating said flow of water from said plurality of orifices in said diverter, wherein said inner surface of said water chamber includes a plurality of baffles interrupted by a corresponding plurality of trenches therebetween, said plurality of baffles and said plurality of trenches curved inward in the distal direction, and wherein said plurality of baffles are configured to strike said flow of water exiting from said plurality of orifices to increase the aeration of said flow of water.
2. The aerator of claim 1 wherein said diverter includes an upper diverter portion including said plurality of orifices and a lower diverter portion extending into said lower body portion.
3. The aerator of claim 2 wherein said lower body portion is movable between a lower position in which said lower body portion is in sealable contact with said lower portion of said diverter, therefore preventing said flow of water from flowing therebetween, and an upper position in which said lower body portion is separated from said lower portion of said diverter thereby permitting said flow of water therebetween.
4. The aerator of claim 3 wherein said water chamber includes a plurality of water openings on the outer periphery thereof, whereby when said lower body portion is in said lower position, said flow of water flows through said plurality of water openings, and when said lower body portion is in said upper position, said flow of water ceases through said plurality of water openings, thereby causing said flow of water to draw air through said plurality of water openings and further aerate said flow of water thereby.
5. The aerator of claim 1 including an inner frame surrounding said diverter and contained within said lower body portion.
6. The aerator of claim 5 wherein said inner frame includes an upper threaded portion, and including an upper body portion threadably affixed to said inner frame.
7. The aerator of claim 6 wherein said upper body portion includes an upper opening, and including a ball joint rotatably mounted within said upper opening in said upper body portion for rotatable mounting of said aerator.
8. The aerator of claim 7 wherein said ball joint comprises a plastic ball joint.
9. The aerator of claim 1 including a pressure compensator mounted on said upper portion of said diverter for regulation of the maximum flow of said flow of water.
10. The aerator of claim 9 including a screen associated with said pressure compensator for filtering said flow of water through said pressure compensator.
