Abstract

Abstract 3. AN ACTUATING DEVICE FOR PRESSURIZING A WORKING FLUID IN A FLUID OPERATED DEVICE COMPRISING: AN OUTER TUBULAR MEMBER HAVING A CYLINDRICAL TUBE WALL DEFINING A LIMITED INTERIOR VOLUME AND CAPABLE OF WITHSTANDING A HIGH INTERNAL FLUID PRESSURE WITHOUT SUBSTANTIALL PERMANENT DEFORMATION; AN INNER METALLIC, TUBULAR MEMBER EXTENDING AXIALLY WITHIN THE OUTER MEMBER AND HAVING A DIAMETER AT ONE END CORRESPONDING SUBSTANTIALLY TO THE INSIDE DIAMETER OF THE OUTER TUBULAR MEMBER, THE INNER MEMBER ALSO HAVING A DEFORMABLE, COLLAPSED, FLUTED WALL PORTION DEFINED BY AT LEAST ONE LONGITUDINALLY EXTENDING INDENTATION ALONG A SECTION OF THE MEMBER, THE WALL PORTION BEING COLLAPSED UPON ITSELF TO SUBSTANTIALLY REDUCE THE INTERIOR VOLUME IN THE COLLAPSED SECTION AND TO CORRESPONDINGLY FORM A SUBSTANTIAL FLUID RECEIVING STORAGE SPACE IN THE LIMITED INTERIOR VOLUME OF THE OUTER TUBULAR MEMBER BETWEEN THE OUTER TUBULAR MEMBER AND THE COLLAPSED WALL PORTION, THE INNER TUBULAR MEMBER ALSO BEING CLOSED AND SEALED AT ONE LONGITUDINAL END TO PREVENT RUPTURE UNDER HIGH EXPLOSIVE PRESSURIZATION; A NON-RUPTURING, SEALING PLUG MOUNTED IN THE OTHER END OF THE INNER TUBULAR MEMBER OPPOSITE THE CLOSED AND SEALED END TO FORM A CLOSED, NON-RUPTURABLE AND DEFORMABLE FLUID CONFINEMENT VESSEL FROM THE INDENTED, SEALED INNER TUBULAR MEMBER, AND AN EXPLOSIVE SQUIB MOUNTED FROM THE SEALING PLUG IN THE CLOSED, FLUID CONFINEMENT SPACE DEFINED WITHIN THE VESSEL AND HAVING SQUIB ACTUATING MEANS EXPOSED ON THE EXTERIOR OF THE SEALING PLUG, THE SQUIB AND SEALING PLUG ALSO BEING IN SEALING RELATIONSHIP TO RETAIN HIGHLY PRESSURIZED GASES RESULTING FROM THE EXPLOSURE OF THE SQUIB IN THE CLOSED, FLUID CONFINEMENT SPACE WHEREBY THE PRESSURIZED GASES WITHIN THE SPACE MAY EXPAND THE LONGITUDINALLY EXTENDING IDENTATION OF THE INNER TUBULAR MEMBER AND DISPLACE THE DEFORMABLE, COLLAPSED WALL PORTION THROUGH THE SUBSTANTIAL FLUID STORAGE SPACE TO THE OUTER TUBULAR MEMBER TO EFFICIENTLY PRESSURIZE ALL THE WORKING FLUID RECEIVED IN THE STORAGE SPACE BETWEEN THE INNER AND OUTER MEMBERS WITHOUT ALLOWING THE PRESSURIZED GASES TO ESCAPE FROM THE CONFINEMENT SPACE OR MIX WITH THE WORKING FLUID PRESSURIZED.
