The cylinder is to serve as a central member. The at least one half-shell is arranged at one axial end of the cylinder, and includes a substantially rotationally symmetrical insert as a boss member and a foot member at the end thereof facing an interior of the high-pressure container and which is embedded in the plastic of the at least one half-shell to substantially form a hollow cone or hollow cylinder. The sleeve is arranged within an inner circumference of the foot member such that the plastic of the half-shell is arranged between the sleeve and the inner circumference of the foot member. The valve is arranged in the boss member, and includes a stem portion arranged in the sleeve. The seal member includes a ring seal forming a seal between the stem portion of the valve and the sleeve.

A high-pressure container includes a cylinder composed of plastic, at least one half-shell composed of plastic, a substantially rotationally symmetrical insert as a boss member, and a sleeve. The cylinder is to serve as a centre member, while the at least one half-shell is at an axial end of the cylinder. The insert as a boss member, the insert having a foot member at an end thereof facing the container interior. The foot member is embedded in the plastic of the half-shell to substantially form a hollow cone or hollow cylinder. The sleeve is pressed into the inner circumference of the foot member at least in a pressing portion of the sleeve. The plastic of the half-shell is arranged between the sleeve and an inner circumference of the foot member so that in a pressing portion, a thin plastic layer of the plastic of the half-shell is pressed between the sleeve and the inner circumference of the foot member.

To provide a filling apparatus capable of suppressing radial movement of a rod-shaped member (connecting pin) of a nozzle, and preventing damages and deformations (recesses and so on) from generating on an outer peripheral surface of the connecting pin. A filling apparatus (100) according to the present invention includes: a storage tank for storing hydrogen fuel; a filling nozzle (10) for filling a hydrogen gas from the storage tank through a fuel filling system to an in-vehicle hydrogen filling tank mounted on a vehicle; a rod-shaped member (2: connecting pin) and a main body portion (1) mounted on the filling nozzle (10); a sealing member (3: laminated sealing member) arranged on (a radially outer peripheral portion of the rod-shaped member of) the main body portion (1); a guide member (4: pressing member), projecting radially inward, mounted on a portion separated from an end side of the rod-shaped member (2) (from a receptacle 20 side in an in-vehicle hydrogen filling tank to the fuel filling system); and means for protecting an outer peripheral surface of the rod-shaped member (2) from slide on the guide member (4).

The invention relates to a tank for storing a cryogenic mixture of liquid and gas, comprising a first casing, a draw-off pipe for drawing off fluid, which has an upstream end connected to said first casing, a filling circuit comprising a first filling pipe with an upstream end to be connected to a fluid source and a downstream end connected to the lower portion of the first casing, said filling circuit comprising a second filling pipe connected to the fluid source and a downstream end connected to the upper portion of the first casing, wherein the upstream ends of said first and second filling pipes are designed to be connected to the same fluid source simultaneously, and a distribution valve assembly which is configured to allow distribution of the fluid in said filling pipes, wherein the tank comprises a sensor assembly which measures the pressure in the first casing, said distribution valve assembly being configured to automatically adjust the pressure in the first casing, during filling, to a predetermined pressure setpoint (Pc) by means of the automatic distribution of the flow rate of fluid from the source in the filling pipes, depending on the pressure setpoint (Pc) and the pressure measured by the sensor assembly.

Disclosed is an apparatus for controlling a pressure vessel including a clamp that surrounds an outer peripheral surface of the pressure vessel fixed to a subject target, a driver that provides a driving force for adjusting a fastening force of the clamp according to an internal pressure of the pressure vessel, and a controller that performs a control such that rotation of the driver is prevented during an abnormal operation of the driver.

Methods, apparatus, and device, for a cryogenic storage system that stores and/or transports a liquid or gas at a temperature below ambient temperature. The cryogenic storage system has an enclosure and a cavity. The cryogenic storage system has a dewar that is positioned within the cavity of the enclosure. The dewar has a payload area that is configured to hold a liquid below ambient temperature. The dewar is configured to hold a liquid below ambient temperature and passively stabilize in an upright position. The dewar is formed with an inner wall and an outer wall and has an opening that allows access to the payload area.

A composite pressure vessel that includes a monolayer liner and a reinforcing structure arranged on top of the liner. The liner is made by injection moulding and includes at least two shells weldable together. Each shell is made of a polymer composition including at least 45% by weight of an aromatic polyamide relative to the total weight of the polymer composition, and at least 10% by weight of an aliphatic polyamide relative to the total weight of the polymer composition.

A cartridge loader includes a lever arm, a hinge axle and a cam centered on the hinge axle, and a housing for receiving a cartridge, the housing having a first end and a second end, the first end adapted to connect to an appliance, and the second end adapted to allow the lever arm to open and close, the housing having an aperture exposing an interior of the housing, the aperture shaped to receive the cartridge and the lever arm, wherein the cam is adapted to assist in seating the cartridge in the housing when the lever arm is closed, and ejecting the cartridge when the lever arm is opened.
