Abstract

In a method for operating a fluid valve for controlling or regulating a fluid, having at least one movable valve component is displaceable with the aid of at least one electrical actuating signal which contains at least one first actuating signal portion which causes an oscillating valve motion of the valve component. Pressure oscillations generated in the fluid due to the oscillating valve motion are detected, and are used for regulation of the oscillating valve motion caused by the first actuating signal portion.
