摘要： A radial shaft sealing ring, especially for use together with a CO2 containing pressure medium, comprises a membrane body (1) and a supporting body (2). A centering element (5) having a radially outer edge (6) is disposed on the supporting body (2) and is not covered by the membrane body (1). The membrane body (1), on its radially inner end, comprises a tilted sealing lip (11) which faces away from the supporting body (2). The supporting body (2) has an axial bore for the shaft (8) and, opposite the sealing lip (11), a supporting face (13) which slopes towards the wall (12) of the bore. The invention is characterized in that the centering element (5), when the radial shaft sealing ring is fitted in a bearing house (4), can be contacted with the interior of the bearing housing (4) in a press fit and that the angle (α) between the supporting face (13) and the wall (12) of the bore of the supporting body (2) ranges between 45° and 55° in a central plane which includes the axis of the radial shaft sealing ring.

摘要： A radial shaft seal for sealing a closed inner chamber (K), filled with a fluid medium (M), on a rotating shaft (W) that is guided out of the inner chamber (K) through a receiving opening (2), relative to an external atmosphere (A), has two membrane bodies (3, 4), each having a sealing membrane (5) having a sealing lip (6) positioned obliquely to the inner chamber (K), where the two sealing lips (6) can be positioned on the shaft (W) in sealing fashion at an axial distance from each other, and a supporting device (7) for supporting the membrane bodies (3, 4) resting thereon. To improve the service life and reduce the internal pressures, it is proposed that the two membrane bodies (3, 4) be positioned at a distance from each other over their entire course, and that the supporting device (7) includes a supporting body (8) located between the membrane bodies (3, 4).

摘要： In a known rotary shaft seal with two sealing lips, a first diaphragm body (20) with a first sealing lip (21) is mounted on a support element (22) and inserted in a second diaphragm body (23) with a second sealing lip (27) that rests against a pressure mount (24) and is mounted in the bearing mount (1). The object of the invention is to prevent the pressure medium from passing through the gap (26) between the two diaphragm bodies, which is open towards the pressure side, and ensure that the first diaphragm body can be displaced in the second along this gap. According to the invention, the first diaphragm body (2) is mounted on a support element (3) and inserted from the unpressurized side into the second diaphragm body (4), which serves to mount the seal in the bearing mount (1), reaches around a pressure mount (5) on the unpressurized side and secures it against axial movement. The rotary shaft seal according to the invention can be used to seal shaft openings leading into vessels containing a pressurized fluid medium, particularly water pumps for internal combustion engines in motor vehicles.
