摘要

The piston has a carrier body (1) fitted with a C-shaped sealing ring (2) having at least one sealing lip (3) and an axial groove (5) open in the direction of the compression space (4). The carrier body has a radial support projection (6) for the sealing ring with an outer edge (7) at a distance (8) from the piston axis (9) equal to the distance of the radial centre plane (12) of the axial groove from the piston axis.
