ABSTRACT:
The bellows comprise identical waves, having sidewalls in which the elastic deformation of the bellows is located and which have a general curved form in the same axial direction. The bellows can thus be put into a state of elastic axial contraction just sufficient, if the bellows are considered in axial half-section, for each sidewall to be at least approximately contiguous at a single point with the other sidewall of the same wave and at a single point with a sidewall of an adjacent respective wave and for the mean wave peak and wave trough directions respectively to be mutually offset in angle, at least one of them being oblique with respect to the axis of the bellows. The relation between the axis travel of the bellows and its life expectancy is thereby optimized.
