Abstract:
1. A differential pressure-controlled locking mechanism, having: a housing; a first pressure chamber which is arranged in the housing and which is connectable to a first ambient zone; a second pressure chamber which is arranged in the housing, which is connectable to a second ambient zone and which is separated from the first pressure chamber by a mobile separating device, the separating device being in an inactive position when the pressure in the first pressure chamber is equal to the pressure in the second pressure chamber, and the separating device being movable from its inactive position into a differential pressure position when a predetermined differential pressure acts on the separating device; an actuation element which is held in a first position by the separating device when the separating device is in its inactive position, and which is movable into a second position when the separating device is in a differential pressure position; and a latch which is held in a locking position when the actuation element is in its first position, and which is movable into an unlocking position when the actuation element is in its second position, wherein the actuation element is designed in the form of a retaining pawl which is rotatable about an axis, wherein the separating device is designed in the form of a pressure plate, which is biased by the force of a first spring into its inactive position.
