Abstract

A fluid proportioning diverter valve capable or selective flow control between 3 fluid ports incorporated inside an elongated valve housing is provided with a central differential diameter bore passing therethrough between the housing ends and adaptable of receiving slidably an elongated valving stem of which a first end serves as a diverter operating means substantially atop thereof while internally separated by a seal from a second stem end provided with an end seal to divert fluid valved between said ports in any flow ratio desired when the stem becomes shifted axially inside the bore to assume various positions permitting fluid flow between either a first fluid supply port means and a first fluid discharge port means entering the bore via a wall or the first fluid supply port means and a third bottom discharge port means inside a bottom closure means and defined by two extreme stem locations inside thereof while also permitting numerous other stem positions therein to feed both the first side wall and the bottom discharge port means from the fluid supply port means, and vice-versa, stem position change means including either manual or pilot controls, including novel mean for stem assembly physically inside the housing bore by a section of an elastomer tubing inserted into the second stem end in final stages of initial valve assembly.
