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.
Claims39
A valve for controlling the delivery of one fluid into another, comprising a first fluid chamber;
- first delivery means for delivering one fluid into said first fluid chamber;
- second delivery means for delivering another fluid into said first fluid chamber;
- a further fluid chamber in fluid flow relation with said first fluid chamber and through which fluid from the latter ordinarily must pass to exit the valve;
- and differential pressure responsive control means responsive to the fluid pressures in said first and further fluid chambers for controlling flow of said first fluid into said first fluid chamber.
A fluid mixer, comprising porous means for passing a fluid therethrough while dispersing such flowing fluid;
- inlet means positioned at least proximate one side of porous means for defining a prescribed area of said porous means at which fluid may enter the same;
- outlet means positioned at least proximate said porous means for defining a prescribed area of the latter at which fluid may leave the same;
- each of said inlet means and outlet means comprising a material substantially less pervious to such fluid than said porous means and means of limited area in such material limiting such respective areas for fluid to enter and to leave said porous material;
- and holding means for holding said porous means, inlet means and outlet means in operative flow through relation.
