Abstract
A press comprises a pressure vessel having an internal closure. The internal closure comprises a cover and a number of elements for transmitting forces in pressurized operation between the cover and the inner wall of the pressure vessel. Each element has a first contact surface adapted to fit a contact surface of the cover and a second contact surface adapted to fit a contact surface of the inner wall of the pressure vessel. The elements are movable away from the contact surface of the cover and the contact surface of the inner wall of the pressure vessel in the direction of the longitudinal center axis of the pressure vessel. A method is provided for opening a pressure vessel.
