Abstract
Apparatus for improving the life of metallic bellows used in a hermetically sealed device having a movable element therein such as, vacuum relays and circuit breakers. The convolutions of the metal bellows are filled by a silicone dielectric gel for an axial length including several such convolutions adjacent to the movable end of the bellows, thereby to damp axial mechanical vibrations and prevent excessive stress build-up in the bellows portions adjacent to the moveable end.
