Abstract
A self-contained thermal mixing valve includes a cap defining a bore, a relief spring and abutment plate within the bore, and a temperature responsive actuator arranged to generate an actuation force against said abutment plate when exposed to a predetermined increase in temperature. A slide is secured to the actuator and moves with the actuator in response to temperature changes. The slide defines a mixing chamber surrounding the temperature sensitive part of the actuator and includes a fluid flow slot axially aligned with the temperature sensitive part of the actuator. The slide is configured to move along a bore which includes axially offset fluid flow inlets, causing the fluid flow slot to vary fluid flow from the fluid flow inlets into the mixing chamber to produce a mixed outflow within a predetermined temperature range. The relief spring provides mechanical relief to the actuator in over-temperature situations.
