| 摘要 |
The present invention relates to an arrangement in an energy-accumulating piston-cylinder device ( 1, 2 ) having a piston ( 2 ) and a cylindrical casing ( 1 ). The invention is characterized by an openable safety valve ( 1 ) arranged in the piston ( 2 ) and/or a discharge duct ( 11 ) together with an element ( 8; 17 ) arranged on the cylindrical casing ( 1 ) or the safety valve ( 10 ) and in the cylinder chamber, which element is designed, in the event of the piston ( 2 ) being inserted into the cylinder chamber by more than a predetermined distance, to act upon the safety valve/the discharge duct ( 10, 11 ) in order to expose the said duct ( 11 ), permitting a discharge of the pressure in the cylinder chamber.
