    摘要: The invention relates to a sealing assembly (1) for sealing a piston rod (2) of a piston compressor, which piston rod extends in an axial direction (A) and can be moved back and forth in the axial direction (A). Said sealing assembly (1) comprises at least one packing chamber (4), wherein the packing chamber (4) is bounded in the axial direction (A) by a first and a second side wall (5, 6), wherein at least one sealing ring (7) or one scraping ring (8) and a spring device (9) are arranged in the packing chamber (4), and wherein a spring device (9) and at least one sealing ring (7) or one scraping ring (8) are arranged one after the other in the axial direction (A) proceeding from the first side wall (5), wherein the sealing ring (7) or the scraping ring (8) lies against the second side wall (6), and wherein the spring device (9) is designed as a magnetic spring and consists of two assemblies (9a, 9b) spaced apart in the axial direction (A), a first assembly (9a) and a second assembly (9b), wherein each assembly (9a, 9b) comprises at least one magnet (10a, 10b), and wherein the magnets (10a, 10b) are arranged in the two assemblies (9a, 9b) in a mutually matched manner in such a way that the two assemblies (9a, 9b) repel each other.
