Abstract

A valve assembly for switching and/or regulating a medium flow of an aerospace engine includes a drive, a valve and a flexible separator element. The drive includes one or more electrically actuatable actuators, which change their length in the direction of a longitudinal axis of the valve assembly when a control voltage is applied to the actuators. The valve includes a valve piston, which can be moved back and forth along the longitudinal axis by the drive and which has a valve member. The flexible separator element delimits a working space of the valve from the drive, as a result of which the medium, which flows through the valve or is present in the working space, is hermetically separated from the drive.
