Abstract
A valve includes a device for shutting off a valve interior. The shutoff device is positioned by a piston which is guided in a cylinder and forms a first chamber and a second chamber in the cylinder. The second chamber communicates with the valve interior through a throttle path, so that the shutoff device is movable in a damped manner in both closing and opening directions.
