The present invention relates to a pressure vessel (1) for a high pressure press, wherein the pressure vessel comprising a first subcylinder (4), a second sub-cylinder (6), pre-stressing means (8), and a securing member (16). The first and the second sub-cylinders (4, 6) are axially connected to form a cylinder body (2) for enclosing a high pressure medium. The first sub- cylinder (4) is in an outer wall provided with a first seat (22) for receiving a first part (24) of the securing member (16) and the second sub-cylinder (6) is in an outer wall provided with a second seat (26) for receiving a second part (28) of the securing member (16). The securing member (16) is fitted in the first and second seats (22, 26). The securing member (16), and the first and second seats (22, 26) are arranged such that the securing member (16), and the first and second seats (22, 26) cooperate to prevent separating axial movement between the first and the second sub-cylinders (4, 6). The pre- stressing means (8) is provided around the envelope surface of the cylinder body (2) such that the cylinder body (2) is radially pre-stressed and such that the securing member (16) is locked in the first and second seats (22, 26).

L'invention concerne un récipient sous pression (1) pour presse haute pression. Le récipient sous pression comprend un premier sous-cylindre (4), un second sous-cylindre (6), des moyens de précontrainte (8), et un élément de fixation (16). Le premier et le second sous-cylindres (4, 6) sont reliés axialement afin de former un corps cylindrique (2) destiné à enfermer un milieu haute pression. Le premier sous-cylindre (4) se trouve dans une paroi extérieure pourvue d'un premier siège (22) destiné à recevoir une première partie (24) de l'élément de fixation (16) et le second sous-cylindre (6) se trouve dans une paroi extérieure pourvue d'un second siège (26) destiné à recevoir une seconde partie (28) de l'élément de fixation (16). Ledit élément de fixation (16) est ajusté dans le premier et le second siège (22, 26). L'élément de fixation (16), et le premier et le second siège (22, 26) sont disposés de sorte que l'élément de fixation (16), et le premier et le second siège (22, 26) coopèrent pour empêcher un mouvement de séparation axial entre le premier et le second sous-cylindre (4, 6). Les moyens de précontrainte (8) sont placés autour de la surface d'enveloppe du corps de cylindre (2) de sorte que ce dernier (2) est radialement précontraint et que l'élément de fixation (16) est verrouillé dans la premier et le second siège (22, 26).
