Abstract
A fail-safe device for a pressure vessel includes a blocking device for a lid thereof, which blocking device is locked by means of a first locking device sensing the internal pressure in the vessel. This device in its turn is provided with a second locking device which works independently by sensing pressure or temperature inside the vessel and locks the first locking device in its locked position whenever pressure or temperature is dangerously high inside the vessel. The object is to assure a safe closing of the lid which is both foolproof and fail-safe.
