  • Faucets are known from everyday life, with a faucet mostly being part of a connection system which, for example, can also include hoses and other components.
  • Conventional faucets have a so-called mixer tap, which is also known as a mixer tap, for metering the water flow and setting the water temperature. The temperature required by the user is set in the appropriate taps by means of the mixer tap by metering and mixing cold and warm water.
  • High-pressure fittings are usually used with direct connection of the fitting to hot water networks, instantaneous water heaters or pressure boilers, where the hot water is below full water line pressure. These fittings are characterized by the fact that they only have two connections, a cold water connection and a hot water connection. The cold and hot water flows are mixed inside the mixer tap by a so-called mixer cartridge and discharged via a common outlet.
  • low-pressure fittings which are suitable for use with a pressureless boiler, have three connection lines.
  • the faucet has a cold water outlet, through which the cold water is fed from the faucet to the boiler, as well as a hot water inlet, through which the water heated by the boiler is fed through the faucet to the outlet.
  • mixing cartridges which actually mix the water flows inside the mixer tap, are established components that were developed as early as the 1940s.
  • mixing cartridges there are two flat-ground ceramic discs that can be moved and rotated against each other.
  • the fixed, underlying ceramic plate in the mixer cartridge has three openings.
  • the adjusting lever of the mixing cartridge By actuating the adjusting lever of the mixing cartridge, the position of the hole in the movable ceramic plate is changed relative to the stationary ceramic plate, and a connection is thereby created between the underlying openings through which the water flows can flow.
  • Corresponding mixing cartridges which are also referred to as mixing units or control cylinders, are for example in the DE 102004035644 B4 and the DE 112017000317 T5 as well as the US 5853023 and the US 5375624 disclosed.
  • the fitting previously used in the kitchen may no longer be compatible with the connection in the new property.
  • the resale value of used faucets the appearance of which is usually tailored to a specific kitchen or bathroom facility, is regularly low, whereas the acquisition costs of a new faucet, which in turn fits the desired design, can be considerable.
  • the problems described above result not only in high costs, but also in considerable effort. It is also not due to the the more faucets needed generates waste that the specialist would like to avoid, especially in times of dwindling resources and greater environmental awareness among consumers.
  • the present invention is therefore based on the primary object of eliminating or at least reducing the disadvantages of the prior art described above. Accordingly, the present invention is based, in particular, on the object of specifying a water tap which can be used in a connection system as a high-pressure and low-pressure fitting, and thereby solves the problems described above.
  • the task was to specify a water tap and an associated connection system, the structure of which is so simple that even a layperson can switch from low-pressure operation to high-pressure operation by making small structural changes.
  • the tap to be specified should not be Form closed reservoirs in which stale water can collect.
  • one of the tasks was to specify a corresponding tap that would allow the conversion between the different variants to be carried out particularly quickly and efficiently.
  • the objective was that the specified water tap is easy and cost-effective to manufacture, namely using only such equipment and process steps that are already used in the manufacture of conventional water taps.
  • the main body of a faucet is regularly referred to as the battery body.
  • This battery body and its configurations are basically familiar to the person skilled in the art.
  • the battery body includes, for example, elements to mount the faucet on a sink, for example with a thread.
  • the water outlet of the tap which can extend from the battery body, for example as a straight or curved tap, is arranged on the battery body.
  • the battery body and the outlet can in principle be produced using conventional methods known to those skilled in the art from any material that is suitable in principle for the production of water taps, metals and metal alloys, in particular iron, steel and aluminum, being particularly suitable.
  • the battery body has a receiving space, the walls and bottom of which are formed by the battery body, and which is provided for receiving a mixing cartridge.
  • Mixing cartridges with an adjusting lever are described in the prior art and conventional mixing cartridges are used in the context of the present invention.
  • Conventional mixing cartridges have a first, a second and a third opening on the end face facing away from the setting lever, with a connection between the different openings can be made.
  • the adjusting lever of corresponding mixing cartridges is intended to be connected, for example, with a one-hand grip and thus enable the consumer to set the water temperature and the volume flow by moving the two ceramic disks arranged in the mixing cartridge against each other.
