The system has a hose (21) rolled on axles (10) and equipped with a hose drum around a rotatable hub (20). A fluid guiding portion is interrupted by fluid conduits (11, 12), where the fluid conduits are attached into the hose. A link (16) and a guide element (26) convert rotation of the hub around the axles with respect to displacement of the hub in an axial direction. The fluid guiding portion is interrupted or not interrupted from the fluid conduits in the axles to a radial bore (22) and a fluid connection device (23) in the hub based on an axial position of the hub. |
