ABSTRACT:
A mixing-valve assembly has a hollow housing, a valve plate in the housing formed with hot- and cold-water inlet ports and an outlet port, a control plate slidable on the valve plate and formed with a mixing cavity alignable with the ports, and a lever assembly pivoted on the control plate for sliding the control plate on the valve plate and thereby bringing the cavity into registration with the ports for water flow therebetween. An adapter disk fitted in the housing is formed with a recessed seat in which the valve plate is snugly engaged and with respective passages communicating with the valve-plate ports. The adapter disk is secured in the housing to fix the valve plate therein.
