Abstract (en)
[origin: WO2016034823A1] This vehicle pressure accumulator comprises a vessel (22) made of thermoplastic, a filament winding (24) around the vessel, a bladder and an insert (20, 30). The insert is made predominantly of a first material and at least partially of a second material which is a thermoplastic that can be welded to the material of which the vessel is made. In addition, the insert is of one piece and shaped in such a way that after the vessel has been welded it can be separated only by destroying the vessel or the insert, and it further comprises means to ensure sealing between the first material and the second material.
