摘要

The device (1) has a housing (3) provided for accommodating a pressure source that produces negative or positive pressure. A compressible tube (7) is led into the housing and flow-connected with the pressure source, where the tube is wound on a rotatable winder (15) and stored in the housing. The tube is designed as a tension spring tube. The winder is arranged in the housing and rotatable around a horizontal rotation axis (14). The winder accommodates multiple winding layers that are arranged adjacent to each other in an axial direction.
