The present invention relates to a high-pressure vessel with inner closure suitable for frequent load changes due to charging and discharging, comprising a forged cylindrical shell with bulbed ends and at least one cover with a frustum-shaped top surface, the cover being centered by supporting elements of the same shape and inclination and being tightened by the prevailing inner pressure. Further features of this high-pressure vessel are the cover bottom sealing which is locally separated from the supporting segments and is radially movable by means of a retaining ring as well as a thin-walled liner with welded-on wearing ring. In view of the frequent opening and closing actions, it is advisable to provide the vessel cover with a small feed-hold cover which is tightened by the prevailing inner pressure and which may be used whenever permitted by the process material characteristics.
