Abstract
A rupture disk assembly is provided which after rupture and pressurized fluid relief, recloses itself to prevent backflow therethrough. The assembly is comprised of a hollow rupture disk support member having a pressurized fluid inlet opening at one end and at least one pressurized fluid discharge port at the other end. A rupture disk is sealingly attached to the support member whereby until the rupture thereof, pressurized fluid is prevented from flowing through the support member to the discharge port therein. A closure member is sealingly positioned over the outlet of the discharge port and is biased towards the outlet of the discharge port so that upon rupture of the rupture disk and the release of pressurized fluid through the support member to the discharge port, the force of the pressurized fluid exerted on the closure member overcomes the bias of and moves the closure member away from the discharge port whereby the pressurized fluid flows therethrough, but upon termination of the flow of pressurized fluid through the discharge port the closure member moves back into a sealing position over the discharge port.
