Abstract
A variable cam comprises a cylindrical skirt with a track followed by a roller movable along a guide comprised within a rotating structure, which is coaxial to the skirt. The track is interrupted at a portion in the region of maximum elevation of the roller. The cam comprises two arc-like elements proximate to the track portions proximate, on opposite sides, to the interruption. Each arc-like element is guided along a path in which, in each position a portion of a first portion of a side of the element is adjacent to the corresponding portion proximate lo the interruption. A second portion of the side, joined with the first portion, is contained within a plane perpendicular to the skin axis. The presence is determined of a track portion within a plane perpendicular to the skirt axis between the ends of the arc-like elements and is adjacent, in every position occupied by the arc-like elements, to a portion of the second portion.
