| 摘要 |
<p>The invention concerns a piston ring (10), in particular a piston ring for a reciprocating compressor, consisting of a first and a second annular element (10a, 10b) with a joint (10e, 10f), the rings (10a, 10b) being disposed concentrically about an axis C. The first ring (10a) has an essentially L-shaped cross-section, with a first arm (10h) extending parallel to axis C and a second arm (10g) extending radially outwards from axis C. The first arm (10h) has an inside surface (10n) and the second arm (10g) has an inside surface (10l), the inside surface (10l) of the second arm (10g) being inclined in the radial direction and the faces (10m, 10k) of the second ring (10b) which face towards the first ring (10a) physically locking with the inside surfaces (10m, 10l) of the first ring (10a).</p> |
