Abstract
A feed-through assembly for a bulkhead for moving and static engine components. The feed-through assembly can be configured to include flexible convolutions that allow for movement and sealing of the engine component relative to the bulkhead. In one aspect, a flexible convoluted spherical element can be provided in the feed-through assembly. In another aspect, a flexible convoluted bellow element can be provided in the feed-through assembly. These flexible convoluted elements can have multiple convolution sections including convolution sections with varying stiffness. The convolution sections can be configured to allow movement of the shaft relative to the bulkhead, including, transverse deflection and tilt.
