Abstract

A liquid mixing valve having a single handle for mixing hot and cold water which incorporates a pair of resilient, tube-like squeeze elements for water passage. A pair of cams, controlled by the handle through a linkage arrangement, restrict the cross-sectional area of the squeeze elements thereby regulating the hot and cold water flow rates.
