Patent ID: 7926676

Claim:
An arrangement for high-pressure pressing, comprising: a high-pressure press including: a circular cylindrical pressure vessel having an internal closure and an inner wall; a cover forming the internal closure, the cover being configured to assume two different positions in an axial direction of the pressure vessel including a first axial position when the pressure vessel is pressurized, and a second axial position when the pressure vessel is substantially unpressurized; an element for transmitting forces generated by pressurization of the pressure vessel, between the cover and the inner wall of the pressure vessel, the element having a first contact surface adapted to fit a third contact surface of the cover and a second contact surface adapted to fit a fourth contact surface of the inner wall of the pressure vessel, the element being configured to assume at least two different positions in the pressure vessel including a lock position in which the element locks the cover in the first axial position during pressurization of the pressure vessel, and a release position in which the element allows removal of the cover from the pressure vessel, wherein a filling element formed as a continuous ring is arranged between a side of the force-transmitting element facing the longitudinal center axis of the pressure vessel and the cover, the filling element being configured to prevent said force-transmitting element from moving inwards toward the longitudinal center axis of the pressure vessel; and an actuator being adapted, in the unpressurized state of the pressure vessel, to move said force-transmitting element toward and away from the longitudinal center axis of the pressure vessel.
