Abstract
Abstract An aeration device for introducing air into a pool of water. The device basically comprises a cylindrically shaped main body portion and a retaining ring for pivotally securing a generally spherically shaped water direction spout within a portion of the main body. The main body has a hollow interior. One end of the main body terminates in a threaded portion adapted to be received in a conventional water supply port found in the wall of the pool. A tube has one end in fluid communication with the spout and the other end exposed to ambient air. As water passes from the water supply port through the water direction spout, a suction is created, drawing air through the tube and into the flow stream of the water for introduction into the pool.

Claim 1
Independent Claim
216 words
An aeration device for use in introducing air into a pool of water, said device comprising: means for securing said device to a conventional water introduction threaded spout, protruding through a wall of an enclosure containing said pool of water; said means for securing said device including a threaded retaining ring; said threaded retaining ring secures a spherical portion of said aeration device and said threaded spout; water-directing means including a conduit for directing water from said spout through said spherical portion into said pool; means within said conduit for creating a suction within said conduit as water passes as a flow stream into the pool; means for responding to said suction by permitting the introduction of ambient air into said flow stream, thus, aerating the water entering the pool; said means for responding comprises a channel creating fluid communication between said flow stream and the exterior of the device, and air means for connecting said channel to a source of ambient air; and said air means is a tube having one end connected to said channel and the other end positioned above the water level of said pool, said tube secured to said wall of said enclosure on the same side of said wall through which said spout protrudes and connects with said aeration device.
