Abstract (en)
[origin: EP0818578A1] The cover (2) is supported in a frame (1). A support surface (22) on the outer circumference of the cover and a contact face (11) on the frame are mainly formed by jacket sections of a straight cylinder, which are defined by two imaginary non-parallel cutting planes (31,32). The upper imaginary cutting plane extends parallel to the top face of the cover, or contains it. The lower plane is at right angles to the cylinder jacket lines. The two planes cut across each other at an angle of between 1 and 15 degrees .
