ABSTRACT:
A mixer valve with a ball-type valving member provided with a control member for being displaced in rotation around two different axes, and provided with openings cooperating with inlet openings for hot and cold water, having tubular gaskets of elastomeric material, and with outlet openings for mixed water, provided in a partially spherical seat of a fixed member, in order to regulate the mixing ratio between hot and cold water and the flow of delivered mixed water, wherein there are provided two inlet openings with tubular gaskets for an incoming flow (of cold or hot water), and one inlet opening with tubular gasket for the other incoming flow. These three inlet openings provided with tubular gaskets are at least approximately aligned along a circle within the partially spherical seat of the fixed member of the valve. For inlet of water, in the ball valving member there is provided an opening, elongated on the whole, whose extension at least approximately corresponds to the total extension of two subsequent inlet openings, including the distance which separates the same.
