Abstract: 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.

Abstract: The invention relates to a arrangement for single-grip mixing faucets operated by turning only, comprising a fixed inlet disc (11) and a rotating regulation disc (16) arranged above each other forming thereby a plane seal, for regulating the amount and ratio of the cold and hot water flowing through the system. The cold water inlet channel (12) connected to the cold water network and the hot water inlet channel (13) are developed in the fixed inlet disc (11) whereas the cold water flow-through channels (17) and the hot water flow-through channels (18) are developed in the rotating regulation disc (16). The cold water flow-through channel (17) and the hot water flow-through channel (18) are connected to the mixing space (19), which is developed either in the regulation disc (16), or in a turning element (20) being in an operation connection with the regulation disc (16), at the side of the regulation disc (16) opposite to the inlet disc (11).
