<p>Described is a cylinder (1) for a lock having a longitudinal axis (2) of main development, a first (4) and a second (5) longitudinal end and a continuum of sections orthogonal to the longitudinal axis, and comprising a main body (3) provided with a hollow (6), and a rotating body (7) turnably housed in the hollow and provided with a groove (8) for the introduction of a coded key, the cylinder comprising a coating body (10) distinct from the main body and having a bottom wall (11) and a side wall (12) defining a respective longitudinal hollow (13), wherein the main body comprises a first portion (15), arranged on the side of the first end and having a tapering (16) on at least one portion of the peripheral development of its outer side surface considered on the orthogonal section, inserted longitudinally into the hollow of the coating body, wherein the shape of the coating body and of the main body are such that the contour of the outer surface of the cylinder on all the orthogonal sections considered on the longitudinal development of the coating body is the same as, or inscribed in, the contour (18) of the outer surface of the cylinder having its maximum size among all the orthogonal sections considered on the remaining part of the cylinder.</p> |
