Document Type and Number:
WIPO Patent Application WO2000073690
Kind Code:
B1
Abstract:
A sealing device for sealing a joint which is constituted by two sealing surfaces (26, 28) facing each other. The sealing surfaces are displaceable in parallel in relation to each other. The sealing device comprises a sealing element (30) consisting of elastomeric materials of at least two different hardnesses. The sealing element (30) is compressed in the joint while contacting the sealing surfaces. The sealing element (30) forms two portions (32) of elastomeric material having low hardness, said portions (32) contacting the sealing surfaces (26, 28). The elastomeric material having high hardness (34) is positioned between the portions having low hardness and contacting the sealing surfaces. The elastomeric material having high hardness (34) is adapted at parallel displacement of the sealing surfaces (26, 28) from the position for forming the joint to increase its size in a direction transversely in relation to the sealing surfaces.
