ABSTRACT:
The improvement of a mixing valve for plumbing in which three ceramic valve discs with appropriate control ducts are positioned parallel to one another in reciprocally watertight manner, in a housing with one hot water and one cold water inlet and one outlet, the disc on the inlet side being a stationary bearing disc, while the second disc rests against this first disc and can be turned from outside in order to control the quantity of flow, and the third disc can be slid linearly against the second disc for temperature adjustment by means of a manually adjustable thermostat that operates laterally to the disc axis, said improvement to be achieved in such manner that flow regulation can be simplified, a motor regulator capable of rotating engages with the second disc, the shaft of which said regulator fits into the stationary disc in a rotating manner and is immovably connected with the second disc, and the regulator can be adjusted by means of an electronic and individually adjustable flow regulator.
