  • Patent number: 8439064
    Abstract: A safety valve for a compressed gas reservoir has an exhaust duct that is connected to the compressed gas reservoir, and a sealing element, which is arranged to move within the exhaust duct, and selectively opens the exhaust duct to the outside depending on an operating phase. The exhaust duct has a greater cross-sectional area on the side facing away from the compressed gas reservoir than on the side facing the compressed reservoir, and a constriction on the side of the sealing element facing away from the compressed reservoir.

  • Patent number: 7677262
    Abstract: A safety valve for a compressed gas storage tank (12) includes a relief conduit (16, 18) provided for fluid connection to an interior chamber (14) of the compressed gas storage tank (12), and a closing member (22) sealing the relief conduit (16, 18); a retaining device (24) being provided which, in a normal condition, locks the closing member (22) in place and which, in safety-critical conditions, opens a cross-sectional flow area (30) in such a manner that the relief conduit (16, 18) is open to the atmosphere. In accordance with the present invention, the closing member (22) is connected to an adjustor (26) which adjusts the cross-sectional flow area (30) of the relief conduit (16, 18) as a function of an upstream interior pressure.
