FIELD: mechanics.
SUBSTANCE: water-mixing cock cartridge includes two ceramic plates adjusting temperature and flow of mixture of two liquids (F, C) entering the cartridge with various temperatures. In addition, it includes thermostatic devices made with possibility at least of automatic shutting off, at least partially, cartridge circulation (Ec) of the hottest entering liquid (C) at the inlet of plates, when mixture temperature (M) exceeds the specified threshold value (Td). At that, the above thermostatic devices include the following: hottest liquid (C) flow shutting off device restricted with cartridge at inlet of plates, and thermostatic element including temperature sensitive part located at least partially on the way of cartridge mixture (M) flow and at outlet of both plates, and movable part made with possibility of being offset relative to temperature sensitive part and moving together with shutting off device. At that, the latter is installed so that it can slide along offset direction (Z-Z) of movable part to cartridge zone restricting the flow of the hottest liquid (C) by means of sealing. Water-mixing cock is equipped with the above cartridge.
EFFECT: increasing operating safety of cock.
