Abstract
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.

Total Claims: 9
Claim 1
Independent Claim
362 words
In 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 outlet pipe, the axis of rotation of the second actuating means coinciding with the axis of rotation of the first actuating means, the inlet and outlet pipes being connected to a fixed body, one of said closure members being fixed to the fixed body, the other of said closure members being mounted for rotation with a distributor core which is rotatably mounted in said body, the first actuating means being connected to control the rotatable position of the distributor core, the mixing chamber being formed between the distributor core and the said other of said closure members around an axial bore which extends to the said other of said closure members and concentric with the central passage therein, at least one lateral slot connecting the axial bore for communication with said mixing chamber, said spigot means being rotatably mounted in said bore and including a transverse groove for bringing the slot into communication with the last-named central passage.

Claim 3
Dependent Claim
35 words
A mixing tap as claimed in claim 1, wherein two nonreturn valves are disposed in said mixing chamber, each valve being associated with one of the peripheral passages of said other of the closure members.
Claim 4
Dependent Claim
62 words
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.
Claim 5
Dependent Claim
87 words
A mixing tap as claimed in claim 1, wherein said distributor core comprises a transverse annular bearing surface disposed between a part of larger diameter and a part of smaller diameter projecting from the larger part, said distributor core being held axially in said body by a ring nut surrounding said part of smaller diameter and threadedly engaging said body, and wherein a locking ring fixed to the body and a friction washer are disposed between the ring nut and said annular portion of the distributor core.
Claim 6
Dependent Claim
42 words
A mixing tap as claimed in claim 4, wherein the internal contour of said locking ring has oblique bearing surfaces, and wherein the part of smaller diameter of said distributor core has transverse grooves adapted to abut against said oblique bearing surfaces.
Claim 7
Dependent Claim
42 words
A mixing tap as claimed in claim 1, wherein said first rotatable actuating means is a lever, and screws fixing the lever to said distributor core, said second rotatable actuating means comprising a knob having a radial bar abutting against said screws.
Claim 8
Dependent Claim
284 words
In 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 outlet pipe, the axis of rotation of the second actuating means coinciding with the axis of rotation of the first actuating means, the two peripheral passages of 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.
