Abstract:
A method of manufacturing a high-pressure fluid vessel includes forming (200) a first portion of a high-pressure fluid vessel with a molding process. The high-pressure fluid vessel includes a stack of capsules. Each capsule includes a first domed end, a second domed end, and a semicylindrical portion extending between and connecting the first domed end to the second domed end. The method further includes forming (202) a second portion of a high-pressure fluid vessel with the molding process. The second portion of the high-pressure fluid vessel is positioned adjacent to the first portion of the high-pressure fluid vessel. The second portion of the high-pressure fluid vessel is welded (208) to the first portion of the high-pressure fluid vessel.
Abstract:
Disclosed is a flat inner container (3), especially an internal tank for a road vehicle, which is surrounded by an outer container (1) and is used for receiving a cryogenic liquid, particularly a fuel. Said inner container (3) is characterized by a combination of the following features: a longitudinally extending monolithic base (4) with a top wall (5) and a bottom wall (6) which are connected to also longitudinally extending sidewalls (7), and with at least two longitudinally extending, substantially straight webs (9) that connect the bottom wall (6) to the top wall (5) so as to form at least one longitudinally extending chamber (10) which is arranged between the webs, extends along the entire length of the base (4) as well as from the bottom wall (6) to the top wall (5), and has a predetermined width between the webs; and at least two caps (11) which tightly seal the two open ends of the base (4) at the periphery; the top wall and/or the bottom wall is/are provided with an arch relative to a planar reference top wall and/or reference bottom wall, the distance of said arch between the inner contour of the top wall and/or the bottom wall and the planar reference top wall and/or reference bottom wall amounting to less than 30 percent of the width of the chamber in the center between the webs.
Abstract:
The present invention comprises a tank for liquefied gases or a so-called cryogenic tank (1) with a tank bottom structure (10) and a tank wall structure (11) arranged around a circumference of said tank bottom structure (10), said tank bottom structure (10) provided with a tank bottom hub (2) adapted for being held by a bottom hub retainer (20) on a tank support structural floor (23). The tank is simple to install, cheap in production and handles in an improved manner forces acting on it.
Abstract:
The invention relates to a hydraulic accumulator, in particular a bladder accumulator, comprising two at least partially adjacent plastic casings (12, 14). The first plastic casing (12) comprises a collar part (16) at least at one end thereof. The aim of the invention is to produce a leakproof accumulator arrangement which is economical to produce. To achieve this, a gap opening (24) between the casings (12, 14) extends up to a point, at which the casings (12, 14) are positioned together in a coaxial manner, and a disk valve (50) is provided as a valve for controlling the supply and discharge of the medium in the opening (10).
