Said mixer valves can be with or without a thermostatic regulator.
When they are without a thermostatic regulator, opening and closing, delivery adjustment, including the variation in the mixer ratio of the water is carried out manually using the control lever. On the other hand, in valves equipped with thermostatic regulators, the variation in the mixer ratio of hot and cold water is autonomous due to the automatic control of the temperature of the mixed water delivered.
Furthermore, also known is the application of a hydraulic pressure balancer on said valves with hot and cold water inputs and suitable to compensate the pressure variations of the water coming from the water mains and in this way to prevent fluctuations in flow so as to maintain the ratio of the delivery of hot and cold water feeding the mixer valve, constant.
Moreover, according to the sate of the technique, the pressure balancer is a separate unit that connects up to the mixer valve directly or
2 by the interposition of hydraulic connections, increasing however the overall size and complexity of the group.
Only in the case where mixer valves without a thermostatic regulator has a solution been proposed and achieved, where the balancer is positioned and housed in a part of the body of the valve itself, even though in a position transversal to the axis of said body. As far as is known, the hot and cold water thermostatic mixer valves have never been provided with an incorporated balancer.
Aims and Summary of the Invention One of the objectives of this invention is therefore to propose and achieve a hot and cold water mixer valve with a pressure balancer positioned advantageously in the valve body, between the latter and the mixing device, associated with the thermostatic unit, so as not to have complementary devices either external to the valve itself or added to it.
Another objective of the invention is to propose and realise a thermostatic hot and cold water mixer valve, which incorporates a pressure balancer without altering its functionality and without increasing the dimensions and consequently the usual overal dimensions.
Still another objective of the invention is to supply a hot and cold water valve mixer, with or without a thermostatic unit, complete with a coaxial pressure balancer, all in the form of a cartridge having overall sizes that allow universal use and insertion, without the need for modifications, in the bodies of taps for bathtubs, showers and the like, instead of and/or in substitution of the traditional thermostatic mixer valves without pressure balancers.
A further objective of the invention is supply a hot and cold mixer valve complete with coaxial balancer and which can be equipped with or without its own water flow opening and closing devices in output and possibly associated also with a two-way distributor.

Detailed Description of the Invention . .
4 As shown, the mixer valve in question is configured and equipped as a cartridge to be inserted as a whole in the body of a tap 10. It comprises a body valve 11 made up of a bottom element 12 and a second top element 13, seal fitted and housing the operating components of the mixer valve.
The body 11 delimits internally a mixing chamber 14 housing a mixer device 15 and temperature control of the mixed water delivered. The bottom device 12, delimits a balancing chamber 16 open towards the mixer chamber and consequently towards the mixer device 15.
The mixer device 15 is associated, in the known way, with a thermostatic bulb 17 and is subject to axial movements in answer to the variations in temperature the thermostatic bulb is subjected to in order to differently open and close the two water input openings 18, 19 to the mixing chamber.
The movements of the mixer device 15 are opposed by two different contrasting springs 20, 21 respectively associated with the device itself and a hood 21 which rests on the summit of the thermostatic bulb 17.
The temperature of the mixed water can be set as required by turning a second knob 23, fixed to a turning shaft 24 associated with the thermostatic bulb 17 by means of a slider 25 which engages with the top spring 21 and, by means of this, with the hood 22 over the bulb.
The bottom element 12 of the body of the valve 11 has laterally, at different levels, some separate input passages 26, 27 for the hot and cold water respectively, and a bottom with an outlet passage of the water towards the delivery point. The hot and cold water reach the feed openings 26, 27 receiving the water to be delivered according to arrows C and F
respectively, through passages connected to the body of tap 10.
The balancing chamber 16 houses a pressure balancer 29 in the form of a piston free to float axially. It has an intermediate portion 30 connected by opposite parts to two annular portions, one lower 31 and one higher 32, with a smaller internal diameter and each crossed by holes or . .
radial slots 31', 32', respectively, on a level with the inlet passages 26, 27.
The external surface of the balancer is guided on the internal surface of the bottom element 12 with the interposition of at least one gasket, whereas the internal surface of the intermediate portion 30 is guided on
The body 11 delimits internally a mixing chamber 14 housing a mixer device 15 and temperature control of the mixed water delivered. The bottom device 12, delimits a balancing chamber 16 open towards the mixer chamber and consequently towards the mixer device 15.
The mixer device 15 is associated, in the known way, with a thermostatic bulb 17 and is subject to axial movements in answer to the variations in temperature the thermostatic bulb is subjected to in order to differently open and close the two water input openings 18, 19 to the mixing chamber.
The movements of the mixer device 15 are opposed by two different contrasting springs 20, 21 respectively associated with the device itself and a hood 21 which rests on the summit of the thermostatic bulb 17.
The temperature of the mixed water can be set as required by turning a second knob 23, fixed to a turning shaft 24 associated with the thermostatic bulb 17 by means of a slider 25 which engages with the top spring 21 and, by means of this, with the hood 22 over the bulb.
The bottom element 12 of the body of the valve 11 has laterally, at different levels, some separate input passages 26, 27 for the hot and cold water respectively, and a bottom with an outlet passage of the water towards the delivery point. The hot and cold water reach the feed openings 26, 27 receiving the water to be delivered according to arrows C and F
respectively, through passages connected to the body of tap 10.
The balancing chamber 16 houses a pressure balancer 29 in the form of a piston free to float axially. It has an intermediate portion 30 connected by opposite parts to two annular portions, one lower 31 and one higher 32, with a smaller internal diameter and each crossed by holes or . .
radial slots 31', 32', respectively, on a level with the inlet passages 26, 27.
The external surface of the balancer is guided on the internal surface of the bottom element 12 with the interposition of at least one gasket, whereas the internal surface of the intermediate portion 30 is guided on
5 the external surface of the mixer device, with the interposition of another gasket. The holes or input slots 31', 32' are on the opposite sides of said intermediate portion 30, above and below the fitted gaskets.
The intermediate portion 30 of the pressure balancer 29 subdivides the balancing chamber 16 into two so-called small chambers with variable volumes: a first lower small chamber 33 for balancing the hot water; a second top small chamber 34 for balancing the cold water. The first small chamber 33 receives from one side, through the radial holes or slots 31', the hot water from the inlet passage 26 and on the other side it is in communication with the radial openings 18 feeding hot water into the mixer valve 14. In the same way, the second small chamber 34 receives from one side, through the radial holes or slots 32', the cold water from the inlet passage 28 and on the other side it communicates with the radial openings 19 feeding cold water into said mixer valve.
As said above, the mixer device 15 sets the feed water inputs 18, 19 to the mixing chamber and is movable axially by the thermostatic bulb 17.
This thermostatic bulb 17 is in contact and is influenced by the temperature of the water passing through the mixing chamber and, by dilating differently depending on the temperature of the water, causes the movements of the mixer device which in this way opens/closes said openings 18, 19 corresponding to the different quantities of the two types of mixed water to maintain the temperature of the water delivered when mixed, constant.
When the pressure of the hot and cold water on entering the passages 26, 27 are the same, the floating piston of the balancer 16 remains in a balanced position and the deliveries of the hot and cold inlet
The intermediate portion 30 of the pressure balancer 29 subdivides the balancing chamber 16 into two so-called small chambers with variable volumes: a first lower small chamber 33 for balancing the hot water; a second top small chamber 34 for balancing the cold water. The first small chamber 33 receives from one side, through the radial holes or slots 31', the hot water from the inlet passage 26 and on the other side it is in communication with the radial openings 18 feeding hot water into the mixer valve 14. In the same way, the second small chamber 34 receives from one side, through the radial holes or slots 32', the cold water from the inlet passage 28 and on the other side it communicates with the radial openings 19 feeding cold water into said mixer valve.
As said above, the mixer device 15 sets the feed water inputs 18, 19 to the mixing chamber and is movable axially by the thermostatic bulb 17.
This thermostatic bulb 17 is in contact and is influenced by the temperature of the water passing through the mixing chamber and, by dilating differently depending on the temperature of the water, causes the movements of the mixer device which in this way opens/closes said openings 18, 19 corresponding to the different quantities of the two types of mixed water to maintain the temperature of the water delivered when mixed, constant.
When the pressure of the hot and cold water on entering the passages 26, 27 are the same, the floating piston of the balancer 16 remains in a balanced position and the deliveries of the hot and cold inlet
6 water are even. Consequently, the ratio of hot and cold water to be mixed does not change and there are no variations in the temperature of the mixed water delivered.
The position of the floating piston changes only when the pressure of the hot and/or cold input water changes. In fact, if the pressure of the hot water that enters the balancing chamber 33 increases, the floating piston of the balancer moves in the direction to close, more or less pronouncedly with its first annular portion 31, the respective inlet passage of the hot water 26, whereas, from the opposite side, the second annular portion 32 of the piston opens more or less pronouncedly the cold water input passage 28. With an increase in the pressure of the cold water we have the opposite; the ratios of the quantities of the cold water are changed to maintain the temperature of the mixed water delivered, constant.
Worthy of note is the fact that the thermostatic mixer valve housing a coaxial pressure balancer such as the one described beforehand may also be the type provided with a closing system, and regulation and/or distribution of the water to be delivered in its base as shown in Fig. 2. Such a system can be made up of a fixed plate 37 and a mobile plate 38 resting and turning above the fixed one. Said plates 37, 38 are associated with the bottom passage 28 of the bottom element 12 and can be held by a covering 39 enclosing the valve body 11.
On one side, the fixed plate can have, for example, two 40, three 41, or even four 42 output passages, as shown respectively in Figs. 3, 4 and 5 for the delivery of water to an equal number of different user outlets, using a distributor 43 with the same number of branches.
On the other side the movable plate 38 is attached to the bottom element 12 of the valve body and has a split or slot 44 which can be selected and positioned in correspondence with each of the exit passages 40, 41, 42 following rotation of the movable plate 38 moved by said bottom =

Furthermore, the movable plate 38 can be turned and stopped on the fixed one in a position at a distance from each output passage so as to close the valve and stop delivery of water. Each position of the mobile plate can be established by a spring loaded stop 46 which engages with a stop notch 47.
