Abstract

Elastic hose (1) of finite length which, in at least one segment (9) of its overall length, has a cross-sectional shape (11) which deviates from a circular cross section (10) up to a pressure considerably below the operating pressure. The sum of the partial segments (9) with the cross section (10) which deviates from the circular shape is less than the overall length of the molded hose (1) and the molded hose (1) has an approximately circular cross section (10) in the remaining partial lengths or segments (2, 5). The transitions (6, 7) from the cross section (11) which deviates from the circular shape to the circular cross section (10) run continuously in transition regions (6, 7). The transition regions (6, 7) are spaced apart from the connecting ends (2, 5) of the molded hose (1) in such a way that they lie outside the clamping zone of the connecting ends (2, 5) to connecting fittings (3). This permits a fast volume increase of the medium to be conducted even at low pressures without losses in fatigue strength, since the rigid clamping location (3, 4) has no influence on the cross section transitions (6, 7).
