Abstract: A hot and cold water sanitary mixing set, comprises a housing having a flow control chamber with a central outlet passage connected from the control chamber to the outside of the housing and with separate hot and cold water supply passages connected into the bottom of the control chamber. A control valve assembly is mounted in the chamber and it comprises an assembly of discs which are arranged in superposed relationship so that one or more of them is movable relative to the others under the control of a single lever which is pivotally mounted in the housing and engages the control disc assembly to move them for control of the flow. The control valve assembly comprises at least three separate superposed discs including a bottom disc having a central discharge passage which overlies the central outlet and provides a flow passage for the discharge of a mixed quantity of water therethrough.

Abstract: A mixing valve mechanism which is operable by a clockwork mechanism has a valve member which is movable in a valve chamber of the housing for opening and closing an outlet passage. The valve member has an upwardly extending follower portion which engages against a cam plate which is rotatably mounted in the housing above the follower. Spring means are provided for urging the follower of the valve member into engagement with the cam, and the cam has a control surface which during a portion of rotation of the cam moves the valve member downwardly into a closed position and which during another portion permits it to move upwardly under the action of the return spring. A handle member is mounted on the housing, and it is coupled by coupling means to the cam to rotate the cam to drive the clockwork during a portion of the rotational movement of the handle member and to lower valve member to close the passage during another portion of the movement.
