Beschreibung
Zusammenfassung:	The device (1) has an emergency operation valve (67) designed such that a pressure level is indirectly adjustable in a control space of the device for an emergency operation. The operation valve is operative only along inflow direction of damping medium. A supplementary surface of valve bodies (35, 45) is pressurized by the damping medium along closing direction of the valve bodies when the valve bodies are impinged by flow of the damping medium through a through-hole (83). A pressure-loaded surface is formed at one pf the valve bodies.
