BLADE SEAL WITH IMPROVED BLADE SEAL PROFILE

摘要

The present invention provides a blade seal for use with a blade that compresses the blade seal to form a seal across a sealing junction. The blade seal includes a recessed ridge for receiving the blade and having a plurality of ridge contact points. When the blade compresses the blade seal to form the seal, the plurality of ridge contact points contacts the blade. The blade seal also may include side lobes extending from the recessed ridge and having respective lobe contact points. When the blade compresses the blade seal, the lobe contact points also contact the blade. The blade seal also includes a secondary sealing portion. When the blade compresses the blade seal to form the seal, the recessed ridge presses against the secondary sealing portion. The multiple contact points between the blade seal and blade, and the presence of a secondary sealing portion, enhance the efficacy of the seal.
