Abstract
Two axially abutting individual rings ( ) arranged in a shared casing recess ( ) at the passage ( ) of a component ( ) to be sealed, which each is formed of several ring segments ( ) pressed against the component ( ) to be sealed by a common peripheral spring ( ). The cover ring ( ) facing the side ( ) to be sealed is radially divided and relieved from pressure by inlet-side radial grooves ( ). The actual sealing ring ( ) is divided by essentially tangential sections. To reduce wear and heat transfer, the cover ring ( ) exhibits a circumferential carrying shoulder ( ) on the side facing the sealing ring ( ), on which sits the sealing ring ( ) with the circumferential peripheral surface ( ) of a twist-out section ( ). In addition, the pressure on the cover ring ( ) is largely relieved by an inner peripheral groove ( ) that is provided on the side of the carrying shoulder ( ) and in contact with the delivery side ( ).
