ABSTRACT:
The present invention relates to a press which comprises a pressure vessel having an internal closure. The internal closure comprises a cover, 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. Said elements are movable away from said contact surface of the cover and said contact surface of the inner wall of the pressure vessel in the direction of the longitudinal centre axis of the pressure vessel. The invention also relates to a method for opening a pressure vessel.
