ABSTRACT:
A gastight seal arrangement for an actuating rod that passes through a wall of a gas-filled enclosure is described. The actuating rod includes a pair of flanges that are spaced longitudinally of the rod and are positioned on opposite sides of the wall of the enclosure. Impact seals on the interior and exterior of the wall surround the actuating rod and are engaged by the respective flanges corresponding to the position of the rod. Additional seal members are provided in the interior of the wall to prevent leakage along the surface of the actuating rod.
