<p>1402763 Mixing valves A M MOEN 28 July 1972 [18 Aug 1971] 35325/72 Heading F2V A mixing valve, particularly for mixing hot and cold water, comprises a body member 14 with hot and cold water inlets 22, 24 and an outlet 20, and a handle 26, 28 incorporating a mixing chamber 34 and movable on the body member, the sleeve 28 of the handle having openings, e.g. 36, through which passages, e.g. 40, connected to the inlets 22, 24 and the outlet 20 can be variably connected to the mixing chamber 34. The mix is varied by rotation of the handle, and the volume of flow by axial movement of the handle. Around the exit, e.g. 50, of each of the inlet passages, e.g. 40, is a sealing member 70 extending almost half way round the body member and having an enlarged port portion 62 which fits into a recess 68 around the exit 50 and forms a wall in contact with the sleeve 28. Fitted over this wall and around the sealing member 70 is a co-extensive support member 78 which may be of plastics. The sealing members and support members are apertured to permit flow to the outlet passage, and have interlocking projections and recesses, inward projection of the sealing members engaging in recesses 75 in the body member.</p> |
