Abstract: 927,003. Valves. A. M. MOEN. June 29, 1959 [June 27, 1958], No. 22321/59. Class 135. The body 10, Fig. 1, of a mixing faucet has hot and cold water inlets 2, 3 that lead via passages 11, 15 and 12, 16, respectively, into a sleeve 14 in which a movable valve closure 17 is slidably and rotatably mounted; the closure 17, which has a port 18 in its wall, is engaged by a pin 19 on the inner end of a valve stem 20 that also carries conical lift closure 21 which co-operates with a sealing ring 32, Fig. 3, in a body extension 25, 26 that embodies apertures 35, 36 outwardly of the closure 21. Packing 41 between the extension 26 and stem 20 is compressed by a nut 42 whilst sealed around extensions 25, 26 is a spout housing 45; outwardly of the extension 26 is a ring 49, Fig. 1, that supports a block 50 pivotally engaged with a handle bracket 51 that is pivoted to the stem 22. An annular chamber 60, Fig. 3, is formed between the housing 45 and the extension 25, 26 into which chamber the apertures 35, 36 open and from which chamber the liquid can pass to the spout through an outlet 56. Within the chamber and overlying the apertures 35, 36 is a rubber sleeve 61 with an annular skirt 64, the sleeve being held in position by members 65, 66. In the chamber 60 is a fluid-actuated closure 80 the lower flange 82 of which is sealed with respect to the housing 45 but which is spaced from the adjacent part 26 of the body; the upper flange is apertured and is located in a groove formed between members 65, 66. The inner part of chamber 60 opens into another chamber in a connector 90, Fig. 1, secured to the body 10 and sealed to the housing 45. After lowering, the stem 20 is rotated to position the port 18 relative to the passages 15 and/or 16 whereby hot, cold or warm water is delivered to a chamber 28 from which it flows past the unseated closure 21 through the apertures 35, 36 unseating the sleeve 61 into the chamber 60, from whence part flows through the aperture in the upper flange of the chamber 80 to the spout via the outlet 56 and part flows between the flange 82 and body extension 25 to the chamber in the connector 90, which chamber leads to a spray connection 6 and a spray hose, not shown, embodying the valve. When the spray valve is opened water passes through the hose instead of filling it and since flange 82 is of greater area that the upper flange of closure 80 the latter is moved inwardly until the aperture through the upper flange is closed by contact with the skirt 64 whereupon further discharge to the spout is prevented. In a modification (Fig. 7, not shown), the rubber sleeve and fluid-actuated closure are dispensed with. In another modification, the valve stem 171, Fig. 8, has a reduced part 150 about which a V-sectioned packing 153 is disposed and a retaining member 154 is located outwardly of the packing. In a further modification, distribution of water from the apertures 192, Fig. 9, to either or both outlets 181, 182 is controlled by a manually-actuated rotary sliding valve 222. In another modification (Fig. 11, not shown), the rotary sliding valve may be dispensed with and replaced by the fluid-actuated valve of Fig. 3. In a further modification, the spout housing 230, Fig. 12, overlies the base 232 whilst lateral inlets 233, 234 are provided within a casing 236.
