<p>The seals have the sliding ring (1, 2, 3, 4, 5) with grooves (r) which at the outer end have a hollow (Zk) according to the lateral plane of sliding rings (1, 2, 3, 4, 5) of 7 νm, and the surface of the groove bottoms (r) in longitudinal section runs alongside the curve (k) of growth (h) up to approximately 4 νm. In the transverse section of grooves (r) the surface of bottom runs alongside the curve (k1) of the growth (h1) up to approximately 4 νm, while in this transverse section both lateral edges are distant to the lateral plane of the sliding rings (1, 2, 3, 4, 5) of the depth (Hp) and (Hk), on of which (Hk) is more distant to the lateral plane of the sliding rings (1, 2, 3, 4, 5) than the other (Hp). And the bigger depth (Hk) is up to 7 νm.</p> |
