Abstract (en)

[origin: DE4313894C1] The invention relates to a duct housing having a sealing-air duct as a stop for a cut-off flap with a double seal around the peripheral edge for blowing in sealing air. The sealing-air duct is divided into sealing-air duct sections. The sealing-air duct sections form expansion joints between them and adjoin the duct housing in the longitudinal direction with a given freedom of movement. The expansion joints are bridged by internal tube sections which are inserted in the sealing-air duct sections with a sealing effect. The longitudinally movable sealing-air duct sections guarantee satisfactory compensation of the thermal expansions occurring as a result of temperature differences. <IMAGE>
