  • Patent number: 10392785
    Abstract: The invention relates to a control cartridge for single-lever mixer taps, comprising a housing in which a ceramic base disk and a rotatable and displaceable ceramic control disk resting on the base disk are situated. An inlet for the cold water and hot water, respectively, and an outlet for the mixed water are situated in the base disk, and the mixed water is diverted in the control disk and leaves the control cartridge via the outlet in the base disk. In order for automatic scalding protection to be integrated into the control cartridge, i.e.

  • Patent number: 10247316
    Abstract: The invention relates to a control cartridge for single-lever mixing taps, comprising a housing having a cylindrical housing wall and a base having a borehole for an inlet for cold water and a borehole for an inlet for hot water. Three ceramic disks are situated one above the other on the base, namely, a lower base disk having a borehole for the inlet for hot water and a borehole for the inlet for cold water, a rotatable and displaceable ceramic control disk which rests on the base disk and has a control edge on the circumferential surface, and an upper bearing disk which is sealed off from the housing or the housing wall. In order for mixed water to be dischargeable either laterally or vertically with the same installation space or the same installation height and installation diameter, it is proposed that the base and the base disk each have a mixed water outlet in addition to the two inlets for cold water and hot water.

  • Patent number: 8844560
    Abstract: The most strained component of a cartridge is the bush, in which the control lever is mounted, using which the control can is moved. Upon actuation of the control lever to open and close the intakes and drains, the bush and thus also the extension of the housing and the front wall thereof are strained by bending. Upon mixing of the cold and hot water streams, friction forces arise in directions, which are perpendicular to one another, between the bush and the front wall of the housing and in the extension of the housing by rotation of the bush. All of these strains can result in hysteresis in the mixing position and in the position of the control cam during the opening and closing movements because of tolerances and play the opening and closing movements because of tolerances and play between the individual components. To overcome the strain issues, the bush bus has the control lever mounted therein is mounted using a conical face and also conical part of the front wall of the cylindrical housing.
