Apparatus for sconfinement of the short-lived hydroxyradical OH associated with ozone reaction processes
First Claim
1. Apparatus for promoting the production of hydroxyradical OH in the course of a reaction of ozone with water, and to confine said hydroxyradical OH reaction products for mixing with the water circulating stream of a pool, comprising:
- a venturi nozzle connected to convey said circulating stream and including a low pressure port;
a confining cavity defined by an upstream and a downstream end having said downstream end connected to said low pressure port;
an air flow restricting ozone generating assembly including an inlet end and an outlet end at the edges of spaced electrodes therebetween connected at said outlet end to said upstream end of said confining cavity; and
a pressure actuated valve assembly communicating between said outlet end and said low pressure port of said venturi nozzle; and
a feedback compensating electrical excitation circuit connected across said spaced electrodes.

Abstract
The output of a flow restricting ozone generator assembly is connected across a check valve to a low pressure port of a venturi nozzle which is connected in series in the water circulating plumbing of a pool or spa. The conveying chamber then stores the water vapors from the water flow through the nozzle which are communicated to the ozone generator to promote the reaction products hydroxyradical OH that is then drawn through the port to mix with the circulating water flow. The check valve at the outlet of the ozone generator is urged to close upon the instance when the flow through the nozzle ceases, terminating the low pressure at its throat and thereby fully confining the reaction products from inadvertent escape.

7. A method for promoting and thereafter confining the reaction products hydroxyradical OH produced in the course of a reaction of ozone with water within the circulating water stream of a pool, comprising the steps of:
-
generating a low pressure by accelerating said circulating water stream through a reduced section of a venturi nozzle; connecting the outlet of said generator cell to said low pressure across a pressure actuated valve assembly; and communicating said low pressure across a valve assembly to the outlet of an ozone generator cell dimensioned to form a flow restriction between the electrodes thereof. - View Dependent Claims (8, 9)
