| 摘要 |
The invention relates to a device which is used to guide at least two flow media having different pressures with a shaft or similar force-transmitting element (10), and a pressure insulating element such as a housing surrounding the shaft or similar. Areas (90a; 96; 98) arranged next to each other in the direction of the axis are determined between the force-transmitting element (10) and the pressure-insulating element by means of sealing elements (70); at least one of the preferably magnetofluidic sealing elements (70) is leakage-free, and two areas (90a; 98) for fluids (A, B) having different pressures flank an area (96) for an auxiliary liquid (H), whereby said area is subdivided by a device (100) into two partial areas (96a, 96b) for two different pressure areas. A conveying medium is allocated to the area (90a) at high pressure and ambient air is allocated to the area (98) at low pressure. The auxiliary liquid (H) is a carrier oil of the magnetofluid, optionally a silicon oil, allocated to the sealing element (70). |
