ABSTRACT:
A Sealing Ring Structure useful for pistons and piston rods has a sealing section and a stressing section for pressing a contact surface of the sealing section into engagement with a moving surface to be sealed. The sealing and stressing sections may be separate rings or may be layers of different material in an integral multilayer laminate. The contact surface of the sealing section is of small axial length compared with the overall length of the structure and is located between a recess in the sealing section on the high pressure side of the structure and an inclined surface of the sealing section which defines a wedge-like gap between the structure and the moving surface to be sealed which gap diverges towards the low pressure end of the structure.
