<p>A valve for enabling independent control of total flow and water temperature of water passed to a shower head comprises a body (110) having square inlet ports (112 and 114) for hot and cold water, respectively. Control of total flow is effected by means of a manual control knob (162) acting via a screw threaded shaft (154) on a first moveable plate (118) having flow control ports (120 and 122) therein which respectively cooperate with the inlet ports (112 and 114). Control of temperature is effected by means of a second plate (126) having flow control ports (130 and 132) therein which respectively cooperate with the ports (120 and 122) in the first plate (118). The first and second plates (118 and 126) are coplanar and are respectively moveable in mutually perpendicular directions. The second plate (126) is moveable by means of a manual lever (178) acting on a shaft (174) carrying a pinion (172) engageable with a rack (170) on the second plate (126).</p> |
