Abstract
An ozone injector device comprising a housing having a water passageway through the housing, a corona tube disposed within the housing, an ozone inlet fitting coupled to the water passageway, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube, and a clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet. The clearing piston is biased upwards, towards to the ozone inlet, and configured to prevent flow of ozone into the water passageway.
Claims16
An ozone injector device comprising:
- a) a housing having a water passageway;
- b) a corona tube disposed within the housing and configured to generate ozone;
- c) an ozone inlet fitting coupled to the water passageway, the ozone inlet fitting defining an ozone inlet that is in fluid communication with the corona tube;
- and
- d) a clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet, the clearing piston configured to prevent flow of ozone into the water passageway, wherein the clearing piston comprises a lower housing coupled to an exterior surface of the water passageway and forming a lower cavity having an opening that permits atmospheric air to flow into and out of the lower cavity, such that pressure changes in the water passageway induce the piston to move between a flow position and a no-flow position.

An ozone injector device comprising:
- a) a housing having a water passageway through the housing;
- b) a corona tube disposed within the housing and configured to generate ozone;
- c) an ozone inlet fitting removably coupled to the water passageway, the ozone inlet fitting defining an ozone inlet that is in fluid communication with the corona tube;
- and
- d) a clearing piston positioned to move into and out of the water passageway to prevent flow of ozone into the water passageway, wherein the clearing piston comprises a lower housing coupled to an exterior surface of the water passageway and forming a lower cavity that is in fluid communication with the water passageway by a pressure inlet and a pressure outlet, such that pressure changes in the water passageway induce the clearing piston to move between a flow position and a no-flow position, wherein the clearing piston comprises a spring positioned within the lower cavity, below the clearing piston, to spring-bias the clearing piston upwards, thereby preventing ozone from entering the water passageway.
