Thermostatic mixing device with arrangement to increase mixing

A thermostatic mixing valve comprising a housing with an inlet port for intake of hot water, an inlet port for intake of cold water, a mixing chamber located in said housing and defined by a perimeter wall, a discharge outlet for discharging mixed water from said mixing chamber, a passage leading into said mixing chamber operably connected to said inlet port for hot water, a second passage leading into said mixing chamber operably connected to said inlet port for cold water, a slide valve slidably movable in relation to said perimeter wall of the mixing chamber and placed so as to control the opening and closing of at least one of said passages for intake of hot water and cold water, a partition which is affixedly connected to said slide valve, a spring located in the housing and connected to the valve to bias the slide valve in a direction corresponding to an opening of the passage for intake of hot water and to a closing of the passage for intake of cold water, and a thermostatic element operating by thermal expansion operably interposed between said partition and the housing to assist the slide valve to move in a direction corresponding to a closing of the passage for intake of hot water and to an opening of the passage for intake of cold water when said thermostatic element undergoes thermal expansion, the thermostatic mixing valve characterized by:

• said partition having a crossing passage located in proximity to the periphery of the partition:
• the housing contains a surface in proximity to the passage for intake of hot water that is inclined towards the interior of the mixing chamber and towards said partition, and opposing the crossing passage in said partition:
• said housing including a separate body member which houses said inlet ports;
• said mixing chamber defined by said peripheral wall and a first insert member and second insert member;
• said passage for intake of cold water being located between said peripheral wall and said first insert member and said passage for intake of hot water being located between said peripheral wall and said second insert member.

A thermostatic mixing valve including a housing with an inlet for hot water, a inlet for cold water, a mixing chamber in communication with said inlets;

• a thermostatically controlled slide valve slidably mounted in said mixing chamber for controlling the extent of opening and closing of the inlets;
• said thermostatic mixing valve characterized by;
• a partition located in said mixing chamber within said slide valve between said inlets;
• cross passages for allowing water from one inlet to pass said partition in said slide valve;
• the other inlet having a surface inclined to direct water centering therethrough toward said partition an inner periphery of said surface being longitudinally aligned to be directly opposing said cross passages.
