(57) Abstract This invention the housing which is pressurized by use media the spindle which from (2) is guided with portable possible method to axial direction regards the sealing device which is used for (1). As for this device, the annular chamber where the spindle (1) and the housing (2) was formed between (5) opening interval to axial direction among them, the multiple packing boxes which are consecutively laid out, namely, the annular seal element (16 and 18. 21, 23, 25 and 27) it has. The annular seal element (), inside the housing such as 16 (40) from tension is loaded beforehand in axial direction the pressure transmission element use media operation by (6).
