Title: (EN) Improvements relating to devices for releasing fluid pressure
Abstract:
(EN) 878,092. Pressure-relieving devices. C.D. PATENTS Ltd. June 11, 1958 [July 1, 1957], No. 20742/57. Class 135. A fluid-pressure relieving device comprises a holder which has two mating parts 1 and 2 co-operating to provide a passage through which fluid can pass a bursting disc 6 of carbon or graphite which normally closes the passage, a support member 15 located in a recess in one of the mating parts so as to be fixed against movement away from the disc but free to move towards it and, when in its furthermost position from the disc, to be spaced therefrom a distance which permits the disc to flex towards this support by an amount which is insufficient to cause rupture of the disc under reversed pressure conditions, the disc having secured to marginal portions of each of the two faces, sealing gaskets 7, 8. The support 15 may also be of carbon. An identification tap 11 or angularly-spaced tabs formed on one of the gaskets may adapt the disc for assembly only in a particular holder (Fig. 1, not shown).
