ABSTRACT:
It is known to construct the actual control elements for a sanitary valve in the form of a cartridge, which can then be inserted in the fitting body.
The problem of the invention is to provide a cartridge which, in the case of compact construction, offers the possibility of implementing different types of sanitary fittings with limited effort and expenditure.
To adapt the cartridge to different functions, it is only necessary to replace one or optionally also several parts of the control device.
The base terminating the cartridge casing serves to form the connection between the water passages of the control device and the channels in the fitting body. The universality of the cartridge proposed by the invention is further improved if it is also possible to replace the base. By replacing the base it is possible to modify a cartridge and place it in the same fitting body and also use the unmodified cartridge for another fitting.
According to a further development of the invention, the rotary movement of the distributor casing is limited by a stop. It is particularly appropriate to allow e.g. the stop fitted to the distributor casing to cooperate with part of the control device and which is replaced for bringing about a different valve characteristic.
According to the invention a thermostat can be placed in the cartridge.
According to a further development, in the distributor casing is placed a distributor having water ducts or passages, through which the water introduced into the valve e.g. flows to the thermostat and from there back to the control device and the cartridge base.
The invention proposes that the water axially enters and leaves the cartridge. This makes it possible to achieve a space-saving, compact construction of the cartridge, which can be inserted in a compact fitting casing. Generally there is plenty of space in the axial direction.
According to the invention the control device can have a disk system. Such disk systems are known in the case of single lever mixing valves and other valves. They normally contain a fixed control disk, also called a distributor disk, as well as a movable control disk in contact therewith. The invention more particularly proposes that the movable control disk can be constructed so as to rotate about a fixed axis. Rotation can take place directly through the distributor casing. To the distributor casing can be connected an actuator, e.g. in the form of a control grip.
According to the invention the control device can have a quantity control, in which the actuation leads to a change in the flow cross-section and therefore a change in the quantity of water passing out of the sanitary fitting per unit of time.
It is also possible for the control device to contain a changeover device for changing between different outlets from the fitting. According to a further development, the changeover device can be actuated with the same actuator as that with which the quantity control is actuated. It can in particular be provided that for actuating the changeover device the actuator is actuated in the same way as for modifying the quantity setting. For example, a rotation beyond a specific position can lead to a changing of the outlets, said position preferably being such that several outlets are closed.
