Abstract
In a sanitary fitting which is controlled without physcial contact at least one sensor is provided through which the water flow can be continuously adjusted. A pilot controlled valve is used for this which is operated by an electric motor. The rotation of the electric motor output shaft is converted into the linear movement of a plunger. This plunger in turn operates a closing device which opens or closes the pilot opening of a membrane. The membrane acts together with a valve seat to regulate the actual water flow. The design of the valve is such that in all positions between the fully open and fully closed position the membrane reliably follows the position of the closing device. Thus a continuous adjustment of the water flow is possible by using minimum power.
