Abstract

A mixer cartridge contains a plate-type control system, the control plate of which is displaceable and twistable by an actuating element configured as a double-armed lever. The displacement leads to an opening and closing of the valve, while the twisting serves to alter the temperature. According to the invention, it is envisioned that the maximum opening and closing position of a holding plate controlling the movable control plate is limited by stops. For the actuating element, a stop is also provided, which acts in the same way, yet is arranged such that it still has a minimum distance from the actuating element when the holding plate is already bearing against the stop.
