摘要

The covering has peripheral devices. A surface (86) of the peripheral device is provided for gasket sealing on a side of the covering. A latter surface is provided on a latter side of the covering (54), which face the former side. A third surface (70) is provided on the former side of the covering, which lies inward in the peripheral device from viewing radially. A fourth surface (62) is provided on the second side of the covering, which is positioned inward in the peripheral device from viewing radially. The covering also has a through hole (50). An independent claim is also included for a method for the distribution of stress in a pressure chamber covering.
