Abstract
A chlorine injector for a swimming pool including a cylinder of chlorine, a disperser tube near the bottom of the pool, and a transfer tube therebetween. The disperser tube is formed of a fluorinated elastomer and has a multiplicity of discharge orifices formed by needle punctures normally closed but opening up responsive to pressure. A pressure regulator between the cylinder and the transfer tube having ports in contact with chlorine gas made of fluorinated material. Addition of chlorine to the pool being controlled by time of injection with constant pressure set by the pressure regulator and by fixed sizes of discharge orifices formed by the punctures under that constant pressure. Disk spacers supporting the disperser tube above the pool bottom.
