Abstract: The diaphragm bellows includes a plurality of diaphragms (1) with outer edges (3) and inner edges (2), wherein diaphragms (1) that follow one another in the direction of the central longitudinal axis (5) of the diaphragm bellows are welded together alternately in the region of their inner edges (2) and in the region of their outer edges (3). A sliding-guidance device of the diaphragm bellows has at least two ring parts (10, 11). The at least two ring parts (10, 11) each extend through at most 180° in the circumferential direction about the longitudinal axis (5) of the diaphragm bellows and each have a guide portion (12) and a holding portion (13) protruding from the guide portion (12) in the direction of the longitudinal axis (5), the holding portion (13) projecting into an intermediate space (6) located between two adjacent diaphragms (1).

Abstract: A guiding device for a metal bellows (3), on at least one bellows end (37) movable along the wall of a housing (10) during the expansion and contraction of the bellows (3). A guiding element is provided between the end body and the housing (10). The guiding element is formed by a plurality of separate guiding bodies (49) disposed in intervals from each other on the circumference of the end body (39).
