ABSTRACT:
The invention relates to a pivotal shut-off and control flap of which the central section (1) comprises an elongate shell (3) which at its two ends is fixedly connected to shaft elements (4) through hub members (6), provision being made for a limited relative movement between the shell and the vane section (2). In an arrangement such as this, the vane section does not undergo excessive deformation, even in the event of severe temperature stressing on one side. The torque required for operating the flap is uniformly transmitted to the vane section.
