Abstract (en)
[origin: EP0759488A1] The upper and lower edges (18,20) are so formed in relation to each other, that in the superimposed state in the peripheral direction location surfaces (28) displaced relatively to one another are formed. One of the edges (18) has several stages equally spaced, in a peripheral direction, between which raised location surfaces are formed. Whilst the other edge (20), at all points of the periphery, has identical radial cross-sections. The lower edge has an inner throat (22), and the upper edge has a complementary radial cross-section, whereby in the superimposed state a hollow space is formed between both edges to accommodate a seal (26).
