  • Nelson Attorney-Young & Thompson ABSTRACT Improvements in mixing water taps, comprising two similar closure members, one member being keyed in the tap body while the other member is keyed inside a distributor core rotatably mounted in the tap body.
  • the improvements relate especially to the provision of a spigot member permitting total modulation of the mixed water delivered by the tap, and also to the arrangement of nonreturn valves which prevent undesired flow from one of the inlet pipes to the other.
  • SHEET 1 [IF 2 MIXING TAPS Mixing cocks or taps are already known which comprise, between a hot water inlet pipe, a cold water inlet pipe and a common outlet pipe, a mixing chamber controlled by two similar closure members brought together along carefully polished contact faces, the said closure members each comprising on the one hand a central passage, facing each other and coupled to the outlet pipe, and on the other hand, two peripheral passages each for coupling to one of the inlet pipes, one of the closure members being rotatably mounted with respect to the other about the axis of the said central passages, under the control of an operating device employed by the user.
  • the present invention has for its object various improvements in mixing taps or cocks of this type, some of these improvements permitting these taps to be provided with additional equipment without increasing their overall volume and size, while others permit the flow characteristics to be improved for the same overall size.
  • FIG. 1 is a view in exploded perspective, with local cross sections of a mixing tap according to the invention
  • FIG. 2 is a view in exploded perspective of the distributor core of this tap and of the elements with which this distributor core is equipped;
  • FIG. 3 is a perspective view of the cock casing associated with the said distributor core
  • F 16. 4 is a view in vertical cross section of this distributor core alone;
  • FlG. 5 is a partial plan view to a different scale of a closure member
  • FIG. 6 is a partial view in transverse section to a larger scale of this closure member, taken along the line VV of FIG. 4.
  • the mixing tap according to the invention comprises a body 10 in which is formed a cylindrical housing 11.
  • the internal wall of this housing 11 is provided at its free extremity with a threaded portion 12.
  • This housing 11 is extended into the interior of the body 10 by a chamber 13 intended to receive in succession a spacing plate 14 and a closure member 15.
  • the closure member 15 is simply formed by a cylindrical disc pierced with a circular central passage 16 and with two peripheral passages 17 and 18, and is keyed inside the chamber 13 by the set of lateral lugs 19 engaged in the corresponding cutout grooves formed in the peripheral wall of the chamber 13.
  • the spacing plate 14 comprises a central passage (not visible in the drawing) and six peripheral passages 20 each intended to support a toric sealing joint (not shown in the drawing).
  • the body 10 comprises a central passage 21 and six identical peripheral passages 22, 23A, 23B, 24, 25A and 25B respectively, each facing a passage of the spacing plate.
  • the central passage 21 communicates with a common outlet pipe 26, the passages 22, 23A and 23B communicate with a hot water inlet pipe 27 and the passages 24, 25A and 25B communicate with a cold water inlet pipe 28.
  • These communications can be effected either through bores at the internal diameters of the inlet pipes, which is the case for the passages 22 and 24 in correspondence with the passages 17, 18 of the closure member 15, or through bores having smaller diameters, which is the case for the passages 23A, 23B, 25A, 258, which are established in angular sectors for which the closure member 15 is not provided with any passage.
  • closure members 15 and 29 are identically the same, and are associated by turning, along carefully polished faces.
  • FIGS. 5 and 6 One of these members, the closure member 15, is shown in part by way of example in FIGS. 5 and 6.
  • the carefully polished face 33A by which it is joined face to face with the other closure member is the front face of FIG. 5, while the other face 338 is at the rear.
  • the central passage 16 is cylindrical, that is to say its outlets 16A, 168 on the faces 33A, 33B are equal circles
  • the passages 17, 18 are flared outwards from the face 33B to the face 33A.
  • the outlets 17B, ]l8B of these passages are equal circles having a smaller diameter than that of the central passage 16, and their centers form a very open angle A with the center of the central passage.
  • outlets 17A, 18A of the passages 17, 18 are polygons which are entirely circumscribed on the circles 17B, 18B, and their two extreme sides are radial sides, that is to say passing through the center of the central passage 16; furthermore, for each peripheral passage 17, 18, one of these radial sides passes through the center of the other peripheral passage 18, 17.
  • the closure member 29 is angularly fixed by a set of radial lugs 34 engaging in a distributor core 35 which is rotatably mounted in the housing 11 of the body 10.
  • This core 35 comprises an internal annular chamber 36 (see FIGS. 2 and 4) known as the mixing chamber, formed round a smaller axial bore 37 facing the passages 31 and 32 of the closure member 29.
  • This chamber 36 is in turn surrounded by an annular groove 38 intended to receive a ring-type sealing joint (not shown).
  • an elastic blade 40 having a generally semicircular form, a tubular spacer 39 being interposed between the blade and the bottom.
  • This blade 40 fixed at its central portion thus has two deformable branches 41, 42 on each side of this central zone and these elastic branches 41, 42 have enlarged extremities 43, 44 which respectively face the passages 17, 18 of the closure member 29. They are intended to serve as nonreturn valves.
  • the axial bore 37 is extended to make contact with the clo sure member 29 which is shown in broken lines in FIG. 4, and is provided laterally with two diametrically opposite slots 45, 46, through which it communicates with the chamber 36. Its axial channel which is provided with a shoulder 47, serves as a housing for a cock casing 48, shown separately in FIG. 3.
  • the spigot 48 which has the same internal diameter as the bore 37 and which has a diametral slot 49, corresponding to the slots 45, 46 of the said bore, is extended by a square operating shaft 50 intended to project to the exterior of the distributor core 35 (F 1G. 1).
  • this core On its outer face, this core has a shoulder 51 surrounding a section 52 of smaller diameter, around which are successively engaged a friction washer 53, a locking washer 54 and a ring nut 55 intended to cooperate with the internal thread 12 of the body so as to hold the assembly inside the said body.
  • the locking washer 54 is provided with two radial lugs 57 for its angular keying in the body 10, and its internal periphery comprises two oblique diametrically opposite bearing surfaces 58. These surfaces are intended to cooperate in abutment with the bottom of transverse slots 59 which are provided symmetrically on the section 52 of the distributor core 35, on each side of its axis, for the purpose of angular limitation of the rotation of this distributor core inside the body 10.
  • an operating lever 61 is fixed by means of screws 60, the lever having a cutaway portion 62. This portion 62 is engaged on a diametral ridge 63 of the distributor core 35 and allows the square operating shaft 50 of the spigot 48 to project.
  • an operating knob 64 On this square shaft 50 is engaged and fixed an operating knob 64, the internal face of which is provided with an annular groove 65 shut off by a radial partition or bar 66.
  • This partition is intended to cooperate with the heads of the screws 60 for the angular limitation of the rotation of the operating knob 64 with respect to the lever 61, that is to say of the spigot 48 with respect to the distributor core 35.
  • the closure members 15, 29 are associated by turning. This turning is efiected by rotation through 180 of one of these members with respect to a line passing on the one hand through the center of its central passage and on the other hand through the center of one ofits peripheral passages. This is suggested in FIG. 5, in which the passage 32 of the closure member 29 has been shown in broken lines, the passages 30 and 31 of this member being assumed to be respectively superimposed on the passages 16 and 17 of the closure member 15.
  • This position corresponds to the case in which the tap delivers hot water for example and at maximum flow rate if the diametral slot of the spigot 48 is in alignment with the slots 45, 46 of the core 35.
  • the path of this hot water is then as follows: pipe 27, passage 22, peripheral passage 20, passages 17 and 31, mixing chamber 36, slots 45 and 46, slot 49, passages 30 and 16, central passage 20, passage 21 and pipe 26.
  • the passages 18 and 32 are tangential (see FIG. 5). From then, if the rotation of the operating lever 61 is continued, cold water is introduced into the mixing chamber over the following path: pipe 28, passage 24, peripheral passage 20, passages 18 and 32. At the same time, the quantity of hot water introduced is reduced due to the progressive closure of the passage 17 of the closure member by the closure member 29. There is therefore delivered a mixture of hot and cold water.
  • the total flow of water delivered by the tap remains unchanged during a mixture of this water; the flow of cold water introduced exactly compensates for the reduced flow ofhot water;
  • the spigot 48 actuated by the knob 64 enables the flow delivered by the tap to be modulated, especially in the case of mixed water.
  • this spigot makes it possible to reduce and even to cut off, except for leakage, the communication between the mixing chamber 36 and the central passages 30, 16 ofthe closure members.
  • a mixing tap of the type comprising a first inlet pipe for hot water and a second inlet pipe for cold water, and a common outlet pipe, a mixing chamber, and control means including two similar closure members having polished surfaces in engagement with one another, each closure member having a central passage, said passages being in alignment with one another and in communication with the outlet pipe, and each closure member also having two peripheral passages, one of said peripheral passages of each closure member being for communication with the first inlet pipe and the other of said peripheral passages of each closure member for communication with the second inlet pipe, one of said closure members being rotatably mounted about the axis of its said central passage, and first rotatable actuating means for controlling the positioning of the said one of said closure members and thereby the mixture of hot and cold water, the improvement comprising: spigot means for controlling the rate of flow to the outlet pipe and disposed between the mixing chamber and said outlet pipe, and second rotatable actuating means for controlling the position of said spigot means and thereby the rate of flow of mixed water to the
  • a mixing tap as claimed in claim 2, wherein said nonreturn valves are formed by the free end portions of a resiliently deformable blade fixed at its middle portion to said distributor core, the end portions of the blade facing the peripheral passages of said other of the closure members and having surface areas greater than the cross sections of said passages.
  • a mixing tap ofthe type comprising a first inlet pipe for hot water and a second inlet pipe for cold water, and a common outlet pipe, a mixing chamber, and control means including two similar closure members having polished surfaces in engagement with one another, each closure member having a central passage, said passages being in alignment with one another and in communication with the outlet pipe, and each closure member also having two peripheral passages, one of said peripheral passages of each closure member being for communication with the first inlet pipe and the other of said peripheral passages of each closure member for communication with the second inlet pipe, one of said closure members being rotatably mounted about the axis of its said central passage, and first rotatable actuating means for controlling the positioning of the said one of said closure members and thereby the mixture of hot and cold water, the improvement comprising: spigot means for controlling the rate of flow to the outlet pipe and disposed between the mixing chamber and said outlet pipe, and second rotatable actuating means for controlling the position of said spigot means and thereby the rate of flow of mixed water to the
  • each closure member having polygonal outlets on at least one of the faces of said closure member, each of said outlets being delimited by two sides disposed along radial lines extending from the center of the central passage, one of said sides of each outlet passing through the center of the other outlet.
