  • Control assembly for thermostatic mixing
    Patent number: 7597270
    Abstract: A mixing valve has a valve housing, a thermostatic valve in the housing having a collar extending outward along an axis from the housing, and a stem axially shiftable in the collar. A sleeve surrounds the collar. A retaining part and interengaging screwthread formations between the part and the housing press the part against the sleeve and collar and thereby secure the collar and the sleeve on the housing against axial and angular displacement relative thereto. A handle is rotatably supported on the sleeve and threaded on the stem.
