Abstract: 1469779 Valves MASCO CORP 13 June 1974 [13 Aug 1973] 26366/74 Heading F2V In a hot and cold water mixing valve the disc 84 of the closure member 30 has a circular pattern of ports 86, 88, 90, 92, 94, 96 which are moved relative to inlet ports 32, 34 to regulate the volume and temperature of the water flowing out of the outlet 18. The closure member is moved along a line joining the centres of the inlet ports to vary the volume of flow by pivoting the handle 62 in the slot 78 about the centre of the spherical portion 56. The temperature of the water is varied by rotating the handle 62 about its own axis which rotation is limited to 180 degrees by stops 100. The handle is joined to the closure member by a lower spherical portion 50 and a pin 81 projecting therefrom into a slot 82 in the closure member. In a modification the closure member is formed with a lower part spherical portion in which the pattern of ports is arranged. The pattern of ports may be replaced by a single arcuate port.
