Patent attributes
A mixing valve cartridge for mixing cold and hot water includes two, superimposed discs disposed in a cartridge housing and forming together a plane seal. One of the superimposed discs constitutes a fixed inlet disc and the other constitutes a control disc arranged on one side of the inlet disc in a movable and rotatable way. A lever is supported by a bearing sitting in a lever holder and is in a driving connection with the control disc via the ceramic moving element that includes a groove for a gasket. A bottom plate having inlet holes is arranged at the other side of the inlet disc and forms a bottom part of the housing. One side of the bottom plate is connected to the inlet disc. The other side of the bottom plate is connectable with connecting ducts. The ceramic moving element has a side facing the control disc that includes an annular stepped part parallel to the axis of the cartridge housing that is connected to the groove. The control disc has an annular stepped part fitting the stepped part of the ceramic moving element. Between the annular stepped parts a radial slot is situated which remains unchanged during operation of the mixing valve.
