Abstract
A method and an arrangement in an energy-accumulating piston-cylinder arrangement (A) has a piston/piston rod part (2), guide/end (3) and tubular casing (1). The casing (1) is provided with a fracture or sprain mark (7) in order to initiate a controlled deformation of the casing in the event of a load that produces a stress in excess of a sprain or fracture limit, or of repeated cyclical stressing that gives rise to material fatigue, so that an excess pressure in the arrangement (A) is discharged past the deformed casing.
