| 摘要 |
The invention relates to a seal (1), which comprises a first sealing lip (2) having a first sealing surface (3) for contacting a first component (4) and at least one other sealing lip (5) having at least one other sealing surface (6) for contacting at least one other component (7). The sealing lips (2, 5) are connected to one another in a lip base region (8) of the seal (1) and are each freely protruding at the end (9, 10) thereof which is opposite the lip base region (8) and on which the sealing surfaces (3, 6) are arranged. On sides thereof opposite the sealing surface (3, 6), each has a contact surface ( 12, 13). The contact surfaces (12, 13) are spaced apart from one another in the relaxed base position. The seal (1) has a working position provided for sealing the components (4, 7) in which the sealing lips (2, 5) lie supported against one another by means of the contact surfaces (12, 13) thereof. The other sealing lip (5) has a sealing-lip wing (20) which, in a working position of the seal (1), forms a pressure surface (21) to which pressure can be applied radially. |

1: Seal (1), in particular an annular seal (1), which comprises a first sealing lip (2) having a first sealing surface (3) for contacting a first, in particular tubular, component (4) and at least one other sealing lip (5) having at least one other sealing surface (6) for contacting at least one other, in particular tubular, component (7), the sealing lips (2, 5) being connected to one another in a lip base region (8) of the seal (1) and each freely protruding at the end (9, 10) which is opposite the lip base region (8) and on which the sealing surfaces (3, 6) are arranged, and on sides thereof opposite the sealing surface (3, 6) each has a contact surface (12, 13), and when the seal (1) is in a relaxed base position a gap (11) is disposed between the first sealing lip (2) and the other sealing lip (5) outside the lip base region (8) so that the contact surfaces (12, 13) are spaced apart from one another in the relaxed base position, and the seal (1) has a working position provided for sealing the components (4, 7) in which the sealing lips (2, 5) lie supported against one another by means of the contact surfaces (12, 13) thereof, and the first sealing lip (2) and the other sealing lip (5) have a continuously increasing thickness (15, 16) from the lip base region (3) in the direction towards the respective freely protruding end (9, 10), wherein the other sealing lip (5) has a sealing-lip wing (20) which, in a working position of the seal (1), forms a pressure surface (21) to which pressure can be applied radially. |
