A single lever operated mixer valve is provided in which a valve member has a section shaped as part of a surface of a solid of revolution. The section allows arcuate movement in two planes of the valve member when it is fitted in a housing. An inner surface of the housing is of a shape complementary to the surface of said section. The movement of the valve member can be in two planes and is under the control of a single lever. The section has inlet port means for two liquids to be mixed. The inlet port means can include passageways extending from the surface of the section to a mixing region of the housing formed either on the opposite side of the valve member to the section or within the valve member. The passageways can be directed to form a substantially undeviated flow of the liquids from the inlet port means to the mixing region and to an outlet of the housing and mixer valve. |
