Tätningsanordning

A sealing arrangement (404) for sealing between surfaces (408, 408, 410, 412, 414} of which at least two surfaces (408, 408) form an outer corner (416). The sealing arrangement (404) comprises a first and a second member (502, 504} and a junction region (508) where said members (502, 504) join. Each member (502, 504) has elongated elastic walls comprising a bottom wail (508, 510) and a top wall (512, 514), the walls defining an inflatable space (520-a, 520-b, 520-c; 820). Each member (502, 504) defines a longitudinal central axis (x-x, y-y}, where the axes (x-x, y-y) form an angle (a) between them. When the space (520-a, 520- b, 520-c; 820) is inflated, the top wall (512) of each member (502, 504) is adapted to move outwardly, from a resting position to a sealing position, in a respective expansion direction (a, b) transverse to the axis (x-x, y-y) of the respective member (502, 504). The top walls (512, 514) form an angle (ß) between them in the junction region (508). The junction region (508) is designed such that when the space (520-a, 520-b, 520-c; 820} is inflated, the top wall (512, 514) of the member (502, 504) is adapted to move substantially the same distance (d1 d2) from the resting position to the sealing position along the entire longitudinal extension of the member (502, 504), An apparatus member (115) and an apparatus for washing and/or dewatering pulp each provided with said sealing arrangement (404).
