Zusammenfassung:The device has a shaft (1), and a control element (2) with rear and front ends (201), which is fixed relative to the shaft and turned around it by a drive unit. A lifting element (4) with rear and front ends is turnable relative to the control element but fixed relative to the shaft. A cage (11) with helical blades (111) is located between control and lifting elements. The front end of the control element and the rear end of the lifting element have rising helical ramps (403). The helical forms of blades and ramps coincide. A pressure surface to transmit axial forces is located on the front end of the lifting element.
