Zusammenfassung:	내용 없음 A dry seal for a rotatable shaft (36) is disclosed. The seal includes an axially monolithic elastomeric sealing element (11) having a shaft side (12) and a casing side(14). The shaft side is provided with a plurality of radially inwardly extending circumferential fins (20), each fin tapering toward an apex (22). The cross-section of each fin in a plane passing through the axis of the shaft (36) is asymmetric. Two spaced fins with apices pointing away from one another define therebetween a circumferential purge chamber (32). Optionally, adjacent fins having apices pointing in the same axial direction away from the purge chamber define therebetween a circumferential sealing chamber.
