Abstract:
1. A mixing valve having an exterior cover, said mixing valve comprising: a valve element within said housing and receiving hot and cold fluid input and being moveable to control at least one of the outlet temperature and flow rate of an outlet fluid mixture from said valve element, a stem interconnected with said valve element and extending therefrom, said stem being moveable to direct movement of said valve element to control at least one of outlet temperature and flow rate, a control element adjacent to said stem and having a predetermined surface setting the limit of movement of said stem in at least one given direction, said control element being a plate positioned within said cover, and an actuating element connected to said control element to translate circular movement of said actuating element into linear movement of said predetermined surface in a direction to vary the limit of travel of said stem towards a position resulting in at least one of a maximum temperature and flow rate of said outlet mixture, said actuating element being positioned in said exterior cover, said actuating element having at least one internally facing cam surface and said control plate interacts with said cam surface to provide translation of said control plate in response to circular movement of said cam surface about a central axis.
