Apparatus for storing and releasing liquid and / or gaseous media under pressure, fuel energy conversion apparatus, and method of assembling apparatus for storing and releasing liquid and / or gaseous media under pressure

摘要

The invention relates to a device for storing and releasing a liquid and / or gaseous medium under pressure, which is made of a plastic material, preferably a polyamide, containing a medium container (1), said medium container At least one valve connection element (2) coupled to (1) and at least one valve element (3, 3a, 3b) coupleable to the valve connection element (2), (1) has a collar (4) which is integrally formed and protrudes from the medium container (1), and the collar (4) comprises a collar outer wall (5) and a collar inner wall (6). Yes. When the valve element (3, 3a) is installed, the collar (4) and the return element (11, 11a, 11b) are compressed together between the partial area (9a) of the wall (9) and the compression part (10). The return elements (11, 11a, 11b) are arranged in such a way that the return elements (11, 11a, 11b) are made of a crosslinked plastic material, preferably a crosslinked polyethylene, The part (10), the collar (4) and the return element (11, 11a, 11b) are combined with the color (4) over the operating time of the device by the compression of the collar (4) and the return element (11, 11a, 11b). ) So that an elastic deformation (X) of the return elements (11, 11a, 11b) greater than the maximum creep deformation (Y) of Are keyed and formed, thereby the creep deformation of the collar (4) (Y) can be compensated through the return element (11, 11a, 11b). The invention further relates to a method for assembling a fuel energy conversion device, a motor vehicle and a device for storing and releasing liquid and / or gaseous media under pressure.
