Mischventil

摘要

The invention relates to a mixing valve cartridge used mainly for mixing cold and hot water, having in the housing (3) of the cartridge two, superimposed discs forming together a plane seal, a fixed inlet disc (6) and a control disc (5) arranged on one side of the inlet disc (6) in a movable and rotable way, said control disc (5) is in a driving connection with a lever (1) supported by a bearing sitting in a lever holder (2) through a ceramic moving element (4), said lever holder is arranged in the housing (3) of the cartridge in a rotable position, at the other side of the inlet disc (6) a bottom plate (9) provided with inlet holes is situated forming the bottom part of the housing (3), one side of said bottom plate (9) is connected to the inlet disc (6), whereas its other side is developed in a manner connectable to the valve provided with connecting ducts , in the ceramic moving element (4) a groove (10) with a gasket (8) in it is developed. The essence of the invention lies in that in the ceramic moving element (4) at its side looking to the control disc (5) a stepped part (11) parallel to the axis of the cartridge of the valve is connected to the groove (10) , whereas in the said control disc (5) a stepped part (12) fitting to the said stepped part (11) is developed, and between the said stepped parts (11,12) a radial slot (x) is situated which remains unchanged also during operation.
