The invention relates to a tank device (1) for storing a gaseous medium, in particular hydrogen, comprising at least one tank reservoir (3), wherein said at least one tank reservoir (3) comprises a tank housing (30) having a tank neck (2). Furthermore, a tank pressure bottom (8) is arranged in the tank neck (2), which tank pressure bottom (8) separates a tank neck space (7) and a tank interior (6) from one another, and wherein said tank neck (2) has an outer thread (10) as an abutment on an outer side (20).

Cladding of the interior of a component part of a pressure vessel is shown. A lining which conforms to at least a portion of the interior geometry of the component is positioned in the interior of the component. The lining is then pressed into the component past its yield strength. The lining is then fused to the component.

The present invention describes a method for producing a leak-tight vessel for holding a gas and/or liquid, comprising the steps of winding a heat-sealable thermoplastic barrier strip around a removable mandrel in such a way that each strip fragment overlaps with a substantially parallel strip fragment over at least a lateral overlapping distance, consolidating the overlapping strip fragments so as to form a gas and/or liquid tight layer, winding a fibrous material around the gas and/or liquid tight layer, thereby leaving an opening large enough for removing the mandrel. The invention also describes a leak-tight vessel produced in this way.

Disclosed herein is an invention related to a gas cylinder safety valve. The disclosed gas cylinder safety valve includes a valve part configured to discharge gas with which a main body is filled and a gas blocking part disposed in the valve part and configured to block a gas flow path in accordance with a pressure inside the main body, wherein the gas blocking part includes a blocking operation part disposed in the valve part, a blocking pin member disposed to be slidable in the blocking operation part and configured to selectively block the gas flow path, and a separation preventing cap coupled to the blocking operation part and configured to prevent separation of the blocking pin member.

A high-pressure tank includes an assembly of a pipe split body having a pipe liner and a pipe reinforcement layer covering an outer circumferential surface of the pipe liner, first dome split body having a first dome liner and a first dome reinforcement layer covering an outer circumferential surface of the first dome liner, and second dome split body having a second dome liner and a second dome reinforcement layer covering an outer circumferential surface of the second dome liner. The pipe split body and the first dome split body are assembled such that the first dome liner is located in the outer portion of the high-pressure tank relative to the pipe liner. The pipe split body and the second dome split body are assembled such that the second dome liner is located in the outer portion of the high-pressure tank relative to the pipe liner.

High-pressure cylinder having an inner core in plastic material and a surface covering of one or more layers of composite material, partially incorporating a nozzle in metal material attached to the upper terminal portion of the neck of the core shaped to receive at least one accessory, such as a tap or a valve. The nozzle is composed of an inner element and an external element screwed one to the other to tighten on the neck of the core. The neck of the core has a slight narrowing of diameter starting from its mouth, such as to determine an internal conical surface suitable for coupling with a corresponding external conical surface of the internal element of the nozzle, and an external conical surface suitable for coupling with a corresponding internal conical surface of the external element of the nozzle.

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.

This invention relates a gas steel container structure for cars, comprising two lateral components, plural intermediate components, plural bonding components, an upper lid and a lower lid. The lateral components are disposed at two sides of the present invention, and each of the lateral components has connectors at two sides. The intermediate components are disposed between the lateral components and each intermediate component has two engaging portions disposed at two sides thereof. The two engaging portions are corresponding to the two connectors or to the two engaging portions of another intermediate component. The plural bonding components are provided to connect the lateral components and the intermediate components, each bonding component has plural locking portions at two sides thereof to interlock with the upper lid and the lower lid correspondingly to form a gas steel container structure for cars.

A pressure vessel configured to store a pressurized fluid is provided including a plurality of lobes. Each lobe includes at least one vertically arranged interior wall. The plurality of lobes are positioned in a side by side configuration such that a first interior wall of a first lobe is positioned adjacent a second interior wall of a second adjacent lobe. The first interior wall and the second interior wall are configured to contact one another at a first point of tangency. A first tangent intersects the first lobe at the first point of tangency and a second tangent intersects the second lobe at the first point of tangency. The first tangent and the second tangent are separated by about 120 degrees.

A pressure vessel comprising a pipe closed at each end with a novel plug/compression cap, the plug at one end of the pipe having a port for connection to a pressure regulating device.
