Beschreibung
Zusammenfassung:	A cover release mechanism to enable a cover to be released whilst being subjected to a high inwardly acting pressure differential. The mechanism comprises: - a caliper mechanism having two or more caliper members mounted within the cover, at least one of which members has an associated sealing member; and - a high energy release mechanism mounted within the cover so that it acts in association with the caliper mechanism 5. Under normal operating conditions, with the cover member secured into position, the or each of the sealing members engages in a detent, normally a throughbore, in the cover. In order to release the cover, the high energy release mechanism is activated causing at least one of the caliper members to move, and the associated sealing means to disengage from the respective detents.
