ABSTRACT:
The invention concerns decompression locks releasing a flap or plate from their closed position in the event of overpressure. A decompression lock, employing the known principle of overcoming the retaining force of a spring (14) to achieve opening, employs a bolt (11) rotatably supported in a longitudinally displaceable support carriage (8). A detent spring (14) keeps the bolt (11) in the closed position and will release it at a predetermined overpressure. During assembly or in the event of forced opening, the decompression lock is moved into the closed position solely by closing the flap or plate.
