EXTRACT OF THE INVENTION The object of the present invention is to prevent the flow of water by coming into contact with the connection parts that are made of leaded brass alloys in a sanitary water valve in the form of a single deactivation valve, or a mixing valve with one or more control levers, with particular emphasis on single lever mixing valves, with waterways that facilitate the inflow of water, and at least one outlet or discharge of water, and with a body of connection to contain the control elements, which remarkably, are assembled together with a construction unit in a cartridge, whereby, the supply tubes that allow the water to flow inward, are connected to the cartridge by means of an insert piece adjacent to the cartridge. In order to prevent contact with the passing water, the interior of the waterways (52) is provided with a protective cover (53, 10, 6) made of a material free of lead, which presents no risk to health.

* * * * * Specification The present invention relates to a sanitary water valve in the form of a single deactivation valve, or of a mixing valve with one or more control levers, giving particular emphasis to single lever mixing valves, with pressure relief valves. water to facilitate the inflow of water, and at least one outlet or discharge of water, and with a connecting body to contain the control elements, which remarkably, are assembled together as a building unit in a cartridge, whereby , the supply tubes that facilitate the entry of water are attached to the cartridge by means of an insert adjacent to the cartridge. The sanitary connections to feed cold, hot, and mixed water, are usually manufactured in copper-zinc alloys, also known under the term brass, since these are easy to work and machine, they have a relatively high degree of stability, and an excellent resistance to corrosion. Lead, whose chipping-breaking properties improve machining, is added as an additional alloy constituent. It is known and proven by scientific research, that heavy metals, which can enter the human body in different ways, can lead to serious diseases and permanent discomforts. In addition, tests have shown that heavy metal components, especially lead, can be absorbed by the fresh water flowing through the tubes carrying water, and the connections made of alloys containing lead, and can be introduced into the human organism when you drink the water. Due to the dangers involved, efforts are being made in some countries to prohibit the use of sanitary connections made of lead-zinc copper alloys, as has been used up to now. This means that sanitary connections made of brass and other lead alloys are considered undesirable in some countries, there is a danger that heavy metals such as lead can be absorbed by the water that flows through and in contact with them. sections that carry water from the valves and connections. In addition to the usual brass connections, it has already been proposed that fittings of sanitary mixer taps be used whose water-carrying sections and functional components are constructed in a large part of materials generally recognized as having no adverse effects on health. These accessories of advanced mixer taps, for example, single-hole combination faucet assemblies, have a brass alloy insert into which the copper supply pipes for hot and cold water are inserted, and if required, an outlet pipe of copper, with compression. The cartridge made of plastic and ceramic, and responsible for controlling the temperature and the flow rate, is kept in a sealed position under pressure with this insert, by means of anchor screws, possibly with interposition of other functional components. In these advanced sanitary connections, the points at which water can come into contact with the structural components composed of a brass alloy are already considerably reduced. This means that the absorption by water of the constituents of the alloy that are detrimental to health is definitely limited. Although high water quality is assured to a great degree, there are still contact points in the tightly inserted supply tube connection areas for cold, hot, and mixed water, and outlet tubes (where they are present ), where water could absorb harmful alloying constituents. Although these amounts of components are extremely low in comparison, they can still be detected with modern sophisticated analyzers, and this can have inconvenient consequences for the manufacturer. The object of the present invention is to eliminate the contact between the water and the components made of brass alloys, and to create a completely "lead-free" sanitary combination tap assembly. The solution to this problem, which includes a favorable development and development of the present invention, is shown in the content of the patent claims that follow this specification. The fundamental idea underlying the present invention is that, in order to avoid contact with the flowing water, the interior of the waterways must have a waterproof protection made of a lead-free material that is not harmful to the water. health. The advantage here is that the contact between the water and the lead alloy sections in the connections is precluded. In accordance with the first convenient version of the present invention, the protective cover consists of a coating of innocuous lead-free material applied to the interior of the waterways, whereby, in addition, the insert for connecting the tubes of supply is made of plastic; in this case, so-called open cartridges could also be used, by which water would enter a waterway with an appropriate inner lining from the cartridge itself; Since all the parts that come in contact with water consist of a lead-free material, the water never touches the lead sections of the tap assembly. In an alternative version of the present invention, the protector is designed as a separate tube or tubular water channel made of a lead-free material not harmful to health, which is then inserted into the waterways, whereby, This water channel is completely sealed from the structural and functional components that consist of leaded brass alloys. One embodiment of the present invention connects the separate water channel and the supply tubes to the cartridge by means of an additional hole in the insert, in such a way that the mixed water from the cartridge enters the separated water channel directly, and it is carried from there to the discharge head without touching parts of the connection containing lead. As already mentioned, the inserts for connecting the supply tubes are usually made of brass containing lead. In order to prevent water from contacting the leaded brass in this area, one embodiment of the present invention uses a disk, made of material that is not harmful to health, to connect the supply pipes and the separate water channel . The disc is located between the cartridge and the insert of brass with lead, it is cushioned with coordinated sealing elements, it is positioned safely, and it is sealed under pressure; this ensures that both the supply tubes and the separate water channel are routed through the brass insert with lead, and only enter the cartridge through the interposed disc, whereby the sealing elements are formed between the disc and the insert, which prevent water from flowing back from the cartridge through the disc to the insert. According to one embodiment of the present invention, the interposed disc is made of a corrosion-proof steel, so that it is capable of absorbing the forces that arise when the functional assembly is held in its position together. According to one embodiment of the present invention, the sealing elements positioned in the area of the connections of the insert, where the supply pipes for hot and cold water, and the separate water channel are put in by brass , for example, they should preferably be inserted into the recesses of the insert, and once the cartridge has been pressed into position with the insert, they fit snugly with the walls of the recesses, and surround the recesses. tubes inserted in a way that does not allow the liquid to penetrate. A discharge head is located at the outlet side end of the separate water channel, and when a sealing component is inserted, it is attached in a connection with the connector body. The discharge head is connected to the water channel separated by means of a cylindrical sealing component, and then it is conducted through a hole in the connection body. The sealing component has two outer ring collars, and the attachment section of its discharge head section, fits securely into place in place between them. In a modified version of this connection, the inlet side of the discharge head has a cylindrical extension of its clamping fixture section, with an inwardly facing drop bolt, which is secured in a corresponding hole in the body of the fixture. Connection. The pressure sealed connection between the discharge head and the outlet side end of the separate water channel is secured by a cylindrical sealing component, which has an outer ring collar that fits radially in a head locating hole. download, and an inner ring collar whose inner section rests on the front area of the separate water channel, or on an inserted adapter, and whose outer front surface rests against a projection in the locating hole in the discharge head. In the single-hole combination faucet assemblies having a liquid distributor between the cartridge and the insert, the liquid distributor is enclosed in a plastic housing, and is set together with the insert in a receptacle of base in the connection body, the end of the inlet side of the separated water channel is fixed, it is sealed under pressure, in an outlet orifice, of the plastic housing, with the help of a cylindrical sealing component. The additional sealing components are placed in the corresponding recesses of the insert, and these hold the cartridge, the liquid distributor, and the insert in a pressure-proof position, and enclose the supply tubes, providing in this way a liquid-tight insulation between the insert made of brass alloy and the functional components that carry water. The cylindrical sealing component established in the outlet hole in the plastic housing of the liquid distributor also has an outer ring collar that remains against the front area and / or in a recess of the outlet orifice, and an inner ring collar which limits the depth to which the outlet tube is inserted in the plastic housing. The proposed design for water valves in accordance with the present invention, and with emphasis on the different types of single-hole combination faucet assemblies, utilizes the favorable properties of brass alloys, as for example, their stability comparatively high, its good machinability, and its ability to work, for particular functional components, but also uses a relatively simple element to ensure that it is not possible for water to come into contact with these functional components. As all structural and functional components that carry water or come in contact with water, are made of materials that are not harmful to health, or are provided with an appropriate coating, the result is a sanitary water tap system where there is no possibility of water absorbing the heavy metal alloy constituents. The present invention will be explained in more detail in the following modalities; the accompanying illustrations show: Figure 1 is a single-hole combination faucet assembly with a closed connection body made of leaded brass alloy. Figure 2 is a single-hole combination faucet assembly, the waterways of which are penetrated by a separate water channel, with a discharge head positioned over the outlet of the separate water channel. Figure 3 is an enlarged illustration between the connection between the discharge head and the separate water channel. Figure 4 is a single-hole combination faucet assembly, with a liquid distributor positioned between the mixing cartridge and the insert, and a separate water channel connected to the plastic housing of the liquid distributor. Figure 5 is an amplified illustration of the deployment of the discharge head on the separate water channel in the mixer tap, established as in Figure 4.

Figure 6 is an amplified illustration of the deployment of the liquid distributor in the mixer tap as set forth in Figure 4, and the connection of the separated water channel to the plastic housing of the liquid distributor. Figure 7 is a single-hole combination faucet assembly with a separable manual spray, whereby the manual spray is connected to the combination faucet assembly by means of a flexible outlet tube. A single-hole combination faucet assembly 1, designed in accordance with the present invention, as illustrated in Figures 1 and 2, with an operating rod 46 for an outlet valve, is established with its supply tubes 11 for the cold and hot water, towards a location hole 4 in a basin or tarja 3, and is constructed as a fixed integral part with the basin / tarja 3 in the usual manner - not illustrated - (Figure 2). The single-hole combination faucet assembly 1 as in Figure 1 has an integrated connecting body 2 made of a lead-brass alloy where an insert 8 is attached which is pressure-bonded to the cartridge 5, and is screwed onto the body 2 by means of the screw 55. A discharge head 51 made of a material that is not harmful to health, is connected to the • outlet in the connecting body 2, and the way of Water 52 between the discharge head 51 and the insert 8 is coated with a waterproof coating 53 made of a lead-free material that is not harmful to health. The coating 53 can be applied in an immersion process, for example. The supply pipes 11 for hot and cold water are established, under pressure, in the plastic insert 8, whereby the additional sealing components 7 are provided at the connection points for these tubes. When the cartridge 5 is securely connected to the insert 8, and is cushioned with the sealing elements, a liquid-proof connection is obtained. In this embodiment, water is conducted through the plastic insert 8 to the cartridge 5, and from there through the insert 8 to the water path 52, where it flows to the discharge head 51.; since the interior of the outlet belonging to the connecting body 2 has a coating 53 of a suitable material, the water never comes into contact with the constituents of lead alloy. Figure 2 shows an embodiment of the present invention, where a separate water channel 10 made of a non-harmful material for health is arranged between the cartridge 5 and the discharge head 9, in order to prevent water touch the brass alloy constituents with lead. Supply pipes 11 for cold water and • hot, and the separated water channel 10, which, for example, are made of copper, are first established under pressure, and by means of brass in the insert 8, which in this case, is made from a brass alloy. An additional disk 6 made of a material not harmful to health, preferably a non-corrosive steel alloy, is placed between the insert 8 and the cartridge 5, in order to connect the tubes 10 and 11 with the cartridge 5 , whereby the tubes 10 and 11 are guided through the insert 8 to the disk 6, and are clamped there; additional sealing elements 7 are provided between the disk 6 and the insert 8, and are put into the recesses 16 of the insert 8; once the insert 8 is pressed into position with the ceramic or plastic cartridge 5, and the disc 6 is placed between the insert 8 the cartridge 5 with the help of the tension rod 48, the elements Sealers 7 enclose the tubes 10 and 11 with a liquid-proof effect, and fit against the sides of the recesses 16 in a liquid-proof manner. This ensures that there is no possibility of the water flowing through coming into contact with the insert 8, which is made of a brass alloy, thus preventing alloy constituents with adverse effects on health from being absorbed by water, and entering the human body in drinking water. As can be seen more clearly, in Figure 3, a discharge head 9 is connected to the outlet side end of the separated water channel 10 by means of a cylindrical sealing component 14. The discharge head is led through a hole 47 to the connection body. In the present version, this part of the connection body 2 can be formed as a cover 49, which, for example, can be plated with chrome as the connection body 2, and is connected to the connection body by means of a screw 50. The sealing component 14 has two outer ring collars 12 and 13, and the holding fitting 45 on the inlet side of the discharge head 9, is positioned securely and pressure-tight between them. The sealing component 14 also has an inlet tilt 15, which makes it easier to connect both this and the discharge head 9 on the separate water channel 10. In compliance with the subject matter of the present invention, the discharge head 9 is also made of a material that is not harmful to health, preferably plastic. Figure 4 shows a single-hole combination faucet assembly 1, with a liquid distributor 20 that transfers the flow out of the water from the discharge head, which belongs to the established mixer tap, and is marked 18 here, to a separate outlet installation, for example, a hand-held sprayer connected over the established mixer tap 1, as an additional feature, and it is attached to the cartridge 5 through another pipe 19. The liquid distributor 20 is set, sealed under pressure , in a plastic housing 17 which is equipped with an outlet orifice 23. In this case, two discs 6 made of a non-corrosive steel, are interposed, and the liquid distributor is then located between the insert 8, which in this case it is also made of a brass alloy, and the cartridge 5. Together with these structural components, it is held tightly in place by means of a tension rod 48 of in a usual way. The supply tubes 11 and the other tube 19 for the mixed water, which lead to the separate outlet installation, are also established in the insert 8, whereby, in accordance with the present invention, the sealing components 7 are They insert into the connection points with the disc 6. These sealing components are held tightly together with the structural components referred to above, and a liquid-proof connection between the water-carrying sections and the insert is ensured. The end of the inlet side of the separate water channel 10 is established, sealed under pressure, in the outlet orifice 23, in the plastic housing 17, by means of a cylindrical sealing component 22, while a discharge head is connected. 18, pressed under pressure, with the outlet side end of the water channel 10 separated, by means of a cylindrical sealing component 27, and joined in a connection with the connecting body 2. For this purpose, the inlet side of the discharge head 18 - as can be seen in detail in Figure 5 - has an extension 24 with a drop bolt 25. The drop bolt 25 slides in the hole 26 of the connecting body 2, thereby ensuring that the discharge head 18 remains in place. The cylindrical sealing component 27, whose function is the pressure sealed connection of the discharge head 18 with the separate water channel 10, has an outer ring collar 28 that fits radially in the locating hole 35 in the discharge head 18, and also an inner ring collar 29 whose inner section 21 rests on the front surface of the separate water channel 10., or on an inserted adapter 30, and whose outer front surface 34 rests against a projection 33 of the fastening fitting 35 on the discharge head 18. The inclination 32 on the inlet side of the sealing component 27, makes it easier to connect the head discharge on the separate water channel 10. The sealing component 22, with which the end of the inlet side of the separate water channel 10 is established in the outlet orifice 23 of the plastic housing 17, has a configuration similar to that of the of the sealant component 27 on the outlet end. The outer ring collar 28 of the sealing component 22 is adjusted, sealed under pressure, against the front area 37, or in a recess 38 of the exit hole 23, while the inner ring collar 29 limits the depth to which it is inserted. the outlet tube 10 in the plastic housing 17. The insert 8 is established together with the liquid distributor 20, which is located in the plastic housing 17, and the cartridge 5, which is tightly held with the piece of insert 8, in a base receptacle 44 in the connecting body 2; This is illustrated in Figure 6..
