Abstract
The sealing device comprises two interengaged members forming a clearance space in which is imprisoned a deformable seal for ensuring pressure-tightness between the members and the internal surface of the press chamber. The member which is in contact with the liquid medium under hydrostatic pressure comprises means for establishing pressure equilibrium within the press chamber and within the clearance space immediately after deformation of the seal.
