An oscillating-nozzle valve with an oscillating nozzle (7) mounted on a diaphragm (12) which is mounted in a fixed position and separates the feed chamber (6c) from the discharge chamber (6), in which the control device (8, 9) determining the oscillation of the oscillating nozzle (7) is provided outside the oscillating-nozzle valve (1). The control transmission elements (18, 19) connected to the oscillating nozzle (7) are each fastened to a diaphragm (20, 21). The diaphragms (20, 21) physically separate the discharge chamber (6) from the environment of the oscillating-nozzle valve or from the control devices (8, 9) of the same (1). Very high degrees of filtering of the delivered liquid up to and over 100 mu m are possible with this type of construction. <IMAGE>
