Beschreibung
Zusammenfassung:	The invention concerns a motor-driven control valve for a water fitting in which the control device 4 executes a linear movement. To produce improved properties, especially simpler design and controllability, the movement of the control device is created by means of an ultrasonic motor 23 so that the shaft 24 of the ultrasonic motor is connected directly to control device 4.
