Abstract
The invention is a sanitary mixer tap with a thermostatic device (1), especially for wall installation, with a thermostat cartridge (3) containing an overtravel unit (9). This unit (9) contains a sleeve (14), at least one pressure spring (15) and at least one pressure component (16) against which the pressure spring (15) acts. At each of its ends the sleeve (14) has a stop (19, 20). One stop (19) at least indirectly takes the thrust of the pressure component (16), the other stop (20) at least indirectly takes the thrust of the pressure spring (15). In order to achieve a simpler and cheaper construction design for the overtravel unit (9) without operational drawbacks, the sleeve (14) can be folded back on the overtravel unit (9) when it is not mounted and both stops (19, 20) will be presented before the pressure spring (15) and the pressure component (16) are inserted.
