Abstract
The invention relates to a cartridge (1) for a water fitting having a stationary bearing disk (2) on which a rotatable ceramic control disk (3) is placed and on which control disk (3) a sliding disk (4) made in particular of plastics material is located. In order that no leaking water can escape from the cartridge (1) even at high water pressure, it is proposed that the control disk (3) is pressed against the stationary bearing disk (2) by a pressure element.

Cartridge for a water fitting having a stationary bearing disk on which a rotatable ceramic control disk is placed and on which control disk a sliding disk made in particular of plastics material is located, wherein the control disk is pressed against the stationary bearing disk by a pressure element.
Method for operating a cartridge having a stationary bearing disk on which a rotatable ceramic control disk is placed and on which control disk a sliding disk made of plastics material is located, wherein a pressure chamber is arranged between the control disk and the sliding disk, one side of the pressure chamber directly or indirectly forming the control disk and the control disk comprising a through-hole which guides water located in the cartridge into the pressure chamber between the control disk and the sliding disk, and it being easier to adjust the cartridge at lower water pressures than at high water pressures due to the water pressure applied to the cartridge pressing the control disk against the stationary bearing disk.
