    摘要： An improved closure assembly for a pressure vessel or pipeline is described, where the closure assembly includes a davit assembly pivotally connecting a closure door to a closure hub where the closure door threadably attaches to the closure hub. The closure door is also threadably attached to the davit assembly where the threaded attachment between with the davit assembly is synchronized or timed with the threaded attachment between the closure door and the closure hub.

    摘要： The invention relates to an apparatus for compressing cryogenic fluid, comprising a sealed enclosure intended to contain a bath of cryogenic fluid, a compression chamber communicating with the bath, an intake system communicating with the compression chamber and configured to allow the inlet of fluid to be compressed into the compression chamber, and a mobile piston for compressing the fluid in the compression chamber, the apparatus also comprising an evacuation system communicating with the compression chamber and configured to allow the outlet of compressed fluid, the piston being mounted at a first end of a rod, the apparatus comprising a mechanism for driving the rod in a back and forth movement along a longitudinal direction, the drive mechanism comprising a motor provided with a rotating shaft and a mechanical system converting the rotary movement of the rotating shaft into a movement in translation of a head sliding along the longitudinal direction and to which a second end of the rod is connected, characterized in that the head is mounted so as to slide and to be guided by two fixed guide rails situated on either side of the head, and in that the head and/or one rail comprises a resilient portion, the resilient portion being configured to generate, on the rail or rails, a force transverse to the longitudinal direction.

    摘要： A valve for closing a gas container includes a valve body with a continuous longitudinal bore along a longitudinal axis and a displaceably-guided valve tappet mounted therein. The valve body extends longitudinally parallel to the axis from a connection region with a connection-side end face to a fastening region with a gas-container-side end face having a smaller diameter than the connection region. The connection region has a stop face that stops a gas container base-body head when the fastening region has been inserted into an opening in the head. The valve body laterally has a double groove in the fastening region that includes two grooves that follow one another longitudinally and that a sealing lug facing away from the longitudinal axis separates to allow the head to be pressed gas-tightly with the fastening region in the double groove region when the fastening region is introduced into the head.

    摘要： A subsurface storage container for a volume of a small molecular gas. An outer casing is axially aligned with an inner liner to define an annulus filled with a non-hardening, incompressible liquid. Sealing assemblies respectively seal upper and lower ends of the annulus and an interior storage space within the inner liner. In some embodiments, the interior storage space stores hydrogen gas at a pressure of about 10,000 psi or higher, and the liquid in the annulus comprises propylene glycol at a selected concentration which is pre-charged at a pressure such as around 3,000 psi. The liquid transfers compressive force from the inner liner to the outer casing to facilitate motor vehicle refueling operations without the need for a compressor to provide the gas at required delivery pressures. The storage container may be arranged into a group or pod that is supported by a support member over a well bore.
