<p>The decompression closure which opens when a predetermined pressure is exceeded comprises a longitudinally displaceable slide (3) bearing a swivel closing bolt(2) which is held in the closed position by the outer end of a leaf spring (1) which resiliently biases the bolt and detachably engages in a detent notch of same. The leaf spring can be single-arm or double-arm. Where the spring has two angled arms one resiliently biases the bolt and detachably engages in the detent notch whilst the other serves solely to fix the spring in the bearing slide and is mounted in same secure against lifting and displacement. The slide can be formed in two parts.</p> |
