Abstract:
A static sealing arrangement, comprising a seal (20) of elastomeric material pre-installed in a groove (15) formed in a first structural member (14) and having a contact portion (21) which, protruding when free, is held tightly pressed against a planar sealing surface (7) of a second structural member (8), characterized in that the elastomeric material possesses the property of swelling greatly under the influence of the medium (M) to be sealed off and is joined directly to the material of the first structural member (14) by being molded onto the same, and in that the cross sectional profile of the seal (20) is designed to be asymmetrical, having the contact portion (21) offset (c) towards the side facing air (L) of the seal (20), and further characterized in that the amount of offset (c) lies in the range of from 0.15 to 0.30 times the width (d) of the groove (15) formed in the first structural member (14), and in that a first wall (17) of the groove (15) facing the medium projects toward the sealing surface (7) of the second structural member (8) by such a distance (a-b), as compared to a second wall (16) of the groove (15) which faces air, that the first wall (17) facing the medium comes to lie adjacent the sealing surface (7) in the final assembled state of the sealing arrangement.
