ABSTRACT:
A mixing valve has a cylindrical body member with inlet and outlet passages in spaced relation to one another. A control stem is movably positioned within the body member which defines a mixing chamber. A split expandable sleeve in the chamber is movable by the control stem to provide for regulation of outlet fluid temperature through mixing. Overall volume control is achieved by longitudinal movement of the control stem and dual valving action.
