Abstract

A sanitary fitting with a fitting body with a hollow cylindrical mixing shaft chamber in which a mixing shaft is rotatably supported about an axis of rotation. A hot and cold water inlet and a mixed water outlet open into the hollow cylindrical mixing shaft chamber, and wherein the mixing shaft has a control contour on the outer circumference which delimits a mixing chamber, which as a function of the rotational position of the mixing shaft fluidically connects the hot water inlet and/or the cold water inlet to the mixed water outlet in order to adjust a mixed water temperature. The mixing chamber of the mixing shaft is fluidically decoupled from the hot water or cold water inlet port while forming a fluid-tight valve gap between a sealing surface of the control contour of the mixing shaft and the inner peripheral wall of the hollow cylindrical mixing shaft chamber.
