Bellows

摘要

A description is given of a one-piece, single- or multi-walled bellows for gaseous or liquid media with bellow waves arranged concentrically next to one another around the axis of the bellows, in the interior of which, in a regular sequence of bellow waves as seen in longitudinal direction of the bellows, internal protective tubular plates are fixed. Starting from their fixing part, these have a tubular extension essentially parallel to the axis and corresponding to the inside diameter of the bellows, the extension extending at least as far as the beginning of the extension of the internal protective tubular plate next in series in the direction of the said extension.
