Control insert for sanitary mixer valves
First Claim
1. A control insert for a sanitary mixer valve having means for connection to hot water and cold water supplies and having at least one outlet, the control insert comprising:
- a fixed control surface which can be connected to water inlet ports of the valve, the fixed control surface having openings defining at least one opening zone for cold water and at least one opening zone for hot water from the supplies;
a movable control surface cooperating with the fixed control surface with two degrees of freedom, and a mixer lever connected to the movable control surface for controlling quantity and mixing ratio as a function of relative position of the fixed and movable control surfaces, movement of the control surfaces controlling alignment of openings in the movable control surface with at least one of the opening zones and the at least one water outlet, wherein at least two separable mechanically coupled mixing flow paths are defined, the flow paths each having controllable connection to the hot water and cold water supplies.

Abstract
A control disk insert for a one-lever mixer valve contains two preferably, planar disks, whereof one fixed disk has at least one opening zone for hot water and at least one opening zone for cold water. The control disk facing the fixed control disk and movable with two degrees of freedom can both completely close and continously completely open the opening zones in the fixed control disk. The opening zones of the fixed control disk and the control edges of the movable control disks are constructed in such a way that the control disk insert has two completely separated, independently operating, but mechanically coupled controlsystems. Both control systems can be used for a common water outlet, or for two separate water outlets.

19. A sanitary mixer valve with a fixed control surface connectable to water inlet ports of the valve, the fixed control surface having at least one opening zone for cold water and at least one opening zone for hot water, a control surface movable with respect to said fixed control surface with two degrees of freedom, a mixer lever attached to the movable control surface for controlling quantity and mixing ratio between the opening zones and at least one out port as a function of position, and wherein:
the fixed and movable control surfaces define at least two separable mechanically coupled controlled mixing flow paths.
