<p>PCT No. PCT/US81/01474 Sec. 371 Date Nov. 2, 1981 Sec. 102(e) Date Nov. 2, 1981 PCT Filed Nov. 2, 1981.This mixing valve for a single spout, single handle faucet provides a stationary valve seat (24) having two fluid apertures, and a valve plate (28), relatively rotatable with respect to the valve seat and pressed against the valve seat surface. The valve plate has a generally central aperture (31) and a peripheral aperture (or bight) (30). The arcuate half-circle shape of the downstream outlets (27 and 27A) of the valve seat hot and cold fluid apertures in combination with the placement and shape of the apertures in the valve plate allows the mixing valve to be adaptable to use with either a knob (53) or lever-type (59) control handle and in back-to-back plumbing installations by simply rotating the valve plate 180 DEG relative to the valve seat upon installation.</p> |
