FIELD: machine building.
SUBSTANCE: invention relates to machine building and can be used in pneumatic-hydraulic systems of other industries. In bellows, comprising corrugated pipe, end fittings and cylindrical springs, with located in them composite rods of round section, wherein the latter are rectilinear. Composite rectilinear rods of round section forming polygon inside said spring counteract forces tending to fold corrugations in direction of X-X axis, protecting against spring coil rupture both at radius of recess and above center of radius of recess.
EFFECT: maintaining bellows stability at higher pressures, reducing labor intensity of rods manufacturing and simplifying their installation into a spring.
