Abstract
A seal between two static turbine parts is provided with a carrier piece comprising a flat metal piece with a middle piece and end pieces each of which is arranged in a groove in the static turbine parts. A second part comprising a flat metal piece and having a middle piece and end pieces which are also arranged in grooves is attached to the middle piece of the carrier. The end pieces are constructed resiliently, ensuring a sealing contact between the end pieces and the inside surfaces of the grooves even in the case of a relative shift of the grooves. The seal does not depend on the level of a pressure differential.
