Beschreibung
Zusammenfassung:	The sealing device (4) is for a shaft (1) accommodated inside a bore (2). It incorporates two convoluted elements (10,20) which interpenetrate with one another. The first of the elements is fixed to the outer diameter of the shaft and the second is fixed to the inner diameter of the bore. The first element has a flange (11) which curls (12) inward so that an annular chamber (13) is formed. The second of the two elements also has a flange (21) which curls inwards and extends into the annular chamber. There are several radial through-bores (15) in the inwardly curled flange of the first sealing element.
