ABSTRACT:
A mixing valve utilizes a sleeve having hot and cold water inlet ports and outlet ports therein. A valve member is reciprocal and rotatable within the sleeve to control the temperature and volume of water passing through the outlet ports. There are port seals positioned in the sleeve hot and cold water inlet ports, which port seals are in sealing contact with the valve member and have openings therein through which pass the inlet water flow of the valve. The cold water port seal opening has a cross sectional area less than that of the hot water port seal opening and there is a restricted passage in the cold water port seal controlling the access of water to the cold water port seal opening.
