Abstract:
A medium-carrying hose, a wall of the hose comprising at least one wall portion which is connected with at least one expansion portion to form a continuous hose casing, so that the circumference of the hose is variable between a minimum value, when the expansion portion is unexpanded, and a maximum value, when the expansion portion is maximally expanded and said expanded portion extends in the transverse and the longitudinal direction of the hose, the wall portions being displaced relative to each other in transverse as well as the longitudinal direction of the hose as the circumference increases and the expansion portion expands, the wall portion has a substantially constant diameter and the expansion portions have a substantially smaller diameter than the wall and the wall and expansion portions are differently formed in different parts along the hose in order to control, during expansion or vibration of the hose, the direction of motion of different parts.
