Abstract
Abstract A fluid mixer includes a porous foam disc for dispersing fluid flowing therethrough, an inlet disc adjacent one surface of the porous disc for limiting the area of the latter through which fluid may enter the same, an outlet disc proximate an opposite side of the porous disc for limiting the area of the latter at which fluid may leave the same, with the radial location of the inlet area being different from that of the outlet area to obtain dispersed fluid flow through the foam disc. Other features include a fluid orifice assembly using an orifice housing held in fluid-tight relation to a fluid fitting by a radially applied force; and a differential pressure responsive mixing control valve for controlling flow of one fluid into a mixing chamber to which another fluid also is delivered.
