Abstract
A thermostatically regulated mixing valve having a housing and a stem extending along an axis in the housing and axially displaceable to adjust the thermostatically regulated temperature of the valve has a control knob that has a nut threaded on the housing, axially linked to the valve stem, and rotatable about the axis in one direction to move axially inward and move the stem axially inward and in the opposite direction to move axially outward and move the stem axially outward. An inner knob part formed with an angularly extending and axially throughgoing slot is axially coupled to the housing and rotationally coupled to the nut so that the inner knob part rotates with the nut but does not move axially therewith. A stop fixed relative to the housing offset from the axis is angularly engageable with an abutment carried on an outer knob part, projecting through the slot, and displaceable between a normal position angularly engageable with the stop and a displaced position angularly out of alignment with the stop. Formations releasably secure the outer knob part on the inner knob part in any of a plurality of angularly offset positions relative to each other.
