The present invention relates to metalworking, in particular to producing vessels from non-heat-treatable aluminium alloys used for tanks and pressure vessels. Disclosed is a method of manufacturing a vessel, the method including: forming a tube by rolling at least one flat blank and abutting the edges thereof, friction stir welding the abutted edges and working at least a part of the welded tube into a shape of the vessel, wherein the flat blank is a sheet of a non-heat-treatable aluminium alloy preliminarily subjected to cold working with permanent deformation within the range of 0.5-15%, and said working of at least one part of the welded tube is hot working at a temperature of 230-520° C. The technical effect is a reduction in vessel weight, an increase in vessel strength, a uniform vessel strength and a reduction in the number of hot working cycles during manufacturing of the vessel. Further, the method provides reduced metal and time consumption in manufacturing a vessel from a non-heat-treatable aluminium alloy, low payload ratio, increased reliability and longer service life of the vessel produced using the method.

A fuel cylinder, such as a high-pressure fluid storage tank, is provided with dual-inlet refilling capabilities. The storage tank may include a main body section with a first domed end portion and a second domed end portion disposed at opposite portions of the main body section. A first inlet assembly and a second inlet assembly are provided at the respective first domed end portion and the second domed end portion. Each inlet assembly is configured to provide fluid communication between a supply of a high-pressure fluid and an interior of the storage tank. Each inlet assembly may include a boss and a tank valve, with each tank valve being in fluid communication with the compressed fluid receptacle. During filling of the storage tank, the high-pressure fluid travels through a compressed fluid receptacle and enters the interior of the storage tank simultaneously through each of the first and second inlet assemblies.

A valve for pressurized fluid having a body housing a fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit having a collection of valve shutter(s) having at least one shutoff valve shutter allowing the circuit to be closed or opened, the valve having a member for manually controlling the collection of valve shutter(s), the control member being mounted to allow the body to move between a rest position in which the collection of valve shutter(s) is in a position in which the circuit is closed and an active position in which the control member actuates the collection of valve shutter(s) into a position in which the circuit is open with a first bore section

A method is provided for forming connections from reinforcing fibers between faces of a wall for a pressure container. The reinforcing fibers are gripped by tufting needles and are pushed through the faces, and loops are formed through which support elements are introduced. A corresponding method produces a pressure container.

A fueling station can include an outer housing comprising a housing volume, a first fluid bladder positioned within the housing volume and configured to hold a first fluid, a second fluid bladder positioned within the housing volume and configured to hold a second fluid, a first fluid conduit in fluid communication with the first fluid bladder, a second fluid conduit in fluid communication with the second bladder, a first hose positioned at least partially outside the outer housing and in fluid communication with both the first and second fluid conduits, and a bi-directional first nozzle connected to an end of the first hose opposite the first and second fluid conduits. The bi-directional first nozzle can be configured to simultaneously release fluid from the first hose and to collect fluid into the first hose. The first fluid bladder can be configured to release fluid through the first conduit in response to introduction of fluid into the second fluid bladder via the second conduit. The second fluid bladder can be configured to release fluid through the second conduit in response to introduction of fluid into the first fluid bladder via the first conduit.

The invention relates to a pressure vessel comprising: a vessel body, wherein, at an upper end of the vessel body, an end section is integrally formed with the vessel body, which has an opening, and a valve arranged in the end section.
