Abstract:
A valve for controlling fluids, comprising a valve member (22) that has an actuating piston (25), which is acted on by a spring (24) in a closing direction of the valve member (22) to contact a valve seat (20) and defines a pressure chamber (29), said pressure chamber (29) is additionally defined by a piezoelectric actuator (30), a movement of said piezoelectric actuator (30) generates a pressure increase in the pressure chamber (29), by means of which the actuating piston (25) is adjusted in an opening direction counter to a force of the spring (24), the actuator (30) is disposed parallel to the actuating piston (25) and radially next to it, and the pressure chamber (29) is divided into a first partial chamber and a second partial chamber, and these partial chambers communicate with each other by way of a conduit (34) that extends crosswise to the axis of the actuating piston, and a throttle location is disposed in said conduit (34).
