Abstract
Abstract A valve with an annular outer body that slides up and down a central tubular column. The movement of the annular outer body relative to the central tubular column is achieved by the movement about a fulcrum of a lever positioned between the annular outer body and a flange on the central tubular column. This lever is free to rotate laterally about the axis of the annular outer body. The central tubular column has orifices around its periphery that allows liquids to pass through and on into one or more exits depending upon the relative position of the annular outer body to this central column. When the lever is actuated, the flow of liquid is diverted through an exit interconnecting with a mixing chamber. The pressure of the liquid entering the valve forces the liquid through the mixing chamber and on through a flexible hose connecting the mixing chamber with a dental appliance for manually directing the jet of liquid.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
232 words
A water aerator valve comprising in combination a center core with a conventional mounting means at one end, a sliding sleeve surrounding said center core, an operating lever provided for moving said sliding sleeve in relation to said center core, said movement providing means of opening and closing an outlet port and likewise alternately opening and closing water entry into an aeration chamber, said outlet port extending through the wall of said sliding sleeve and connecting with an adaptor orifice, an inlet port for the reception of water under preSsure, a spring pressure plate which retains a compression spring, said spring pressure plate being attached by conventional means to the end of said center core, said compression spring applying pressure against an anular flange within said sliding sleeve, thus, said sliding sleeve maintaining pressure against said operating lever, said operating lever likewise being held by the said spring pressure against a flange extending from said center core, a splash wall for directing the flow of water into an aeration chamber, said splash wall being attached to the inside perimeter of said aeration chamber and surrounding a flow smoother which is positioned in the center of said aeration chamber, said flow smoother being attached by conventional means to said spring pressure plate, a plurality of air entry apertures in the outer wall of said aeration chamber, a mesh protector across an exit orifice.
Claim 2
Dependent Claim

A water aerator valve comprising in combination a center core with a conventional mounting means at one end, a sliding sleeve surrounding said center core, an operating lever provided for moving said sliding sleeve in relation to said center core, said movement providing means of opening and closing an outlet port and likewise alternately opening and closing water entry into an aeration chamber, said outlet port extending through the wall of said sliding sleeve and connecting with an adaptor orifice, an inlet port for the reception of water under preSsure, a spring pressure plate which retains a compression spring, said spring pressure plate being attached by conventional means to the end of said center core, said compression spring applying pressure against an anular flange within said sliding sleeve, thus, said sliding sleeve maintaining pressure against said operating lever, said operating lever likewise being held by the said spring pressure against a flange extending from said center core, a splash wall for directing the flow of water into an aeration chamber, said splash wall being attached to the inside perimeter of said aeration chamber and surrounding a flow smoother which is positioned in the center of said aeration chamber, said flow smoother being attached by conventional means to said spring pressure plate, a plurality of air entry apertures in the outer wall of said aeration chamber, a mesh protector across an exit orifice.
Claim 3
Dependent Claim
39 words
The water aerator valve as defined in claim 1 characterized in that said operating lever can be rotationally displaced about the axis of said sliding sleeve throat while also moveable in an inclined position relative to said sliding sleeve.
Claim 4
Dependent Claim
33 words
The water aerator valve as defined in claim 2 characterized in that provision of said gaskets of a suitable material provides a water-tight seal between said center core and said sliding sleeve shaft.
Claim 5
Dependent Claim
48 words
The water aerator valve as defined in claim 3 characterized in that provision of a plurality of channels around the periphery of said spring pressure plate causes turbulence in the flow of water passing between the periphery of said spring pressure plate and wall of said sliding sleeve.
Claim 6
Dependent Claim
45 words
The water aerator valve as defined in claim 4 characterized in that provision of said splash wall extending around the interior of said aeration chamber directs the flow of turbulent water away from the air entry apertures and towards the center of the aeration chamber.
Claim 7
Dependent Claim
42 words
The water aeration valve as defined in claim 5 characterized in that provision of said flow smoother in the center of the aeration chamber provides a means of reducing the turbulence of the aerated water prior to exiting from the aerator valve.
