Mixer tap for a thermal wave massage device

A mixer tap for a thermal wave massage device, said mixer tap comprising:

• a housing;
• a number of inlet ports for hot and cold water;
• an operating handle;
• at least one contact pair, including:
• a movable part having a first contact surface of a flat, or a cylindrical, or a spherical type, and movable passage means for passing water therethrough made in the movable part, and
• an immovable part having a second contact surface of a flat, or cylindrical, or spherical type corresponding to the first contact surface, and immovable passage means for passing water therethrough made in the immovable part,
• wherein said immovable part is secured substantially to the housing, said at least one contact pair having two degrees of freedom in a possible motion of said movable and immovable parts relative to each other;
• and
• at least one outlet port for warm water and at least one outlet port for tepid water, said outlet ports are associated with said passage means;
• wherein the first and second contact surfaces are placed in contact with each other, and the passage means are so configured,
• that a relative position of the movable and immovable parts against each other regulate a proportion between the hot and cold water flowing into said outlet ports, and a shift of the movable part in the direction of one said degree of freedom determines a temperature difference between the warm and tepid water, and a shift in the direction of the other degree of freedom determines an average temperature of the warm and tepid water.
