Abstract:
1. A mixing valve having a housing and an exterior cover cooperatively arranged with said housing, said mixing valve comprising: valve means within said housing and constructed and arranged for receiving hot and cold fluid input and being movable to independently control an outlet temperature and flow rate of an outlet fluid mixture from said valve means; a stem interconnected with said valve means and extending therefrom, said stem being movable to direct movement of said valve means to control outlet temperature and flow rate; a first control element adjacent to said stem and having a first predetermined surface setting the limit of movement of said stem in at least one given direction, said first control element being a plate positioned within said cover; a first actuating element connected to said first control element and being constructed and arranged to translate circular movement of said first actuating element into linear movement of said first predetermined surface in a direction to vary the limit of travel of said stem towards a position resulting in a maximum temperature of said outlet fluid mixture; a second control element adjacent to said stem and having a second predetermined surface setting the limit of movement of said stem in at least one given direction, said second control element being a plate positioned within said cover; and a second actuating element connected to said second control element to translate circular movement of said second actuating element into linear movement of said second predetermined surface in a direction to vary the limit of travel of said stem towards a position resulting in a maximum flow rate of said outlet fluid mixture.
