Abstract
A cylindrical actuator sub-assembly (100, 200, 300) comprising: an element (14, 24, 34) movable along a longitudinal axis (A), at least one actuating member and a guidance mechanism suitable for guiding the element, wherein aid guidance mechanism includes a first ring-shaped lever (11, 21, 31) and a second ring-shaped lever (11′, 21′, 31′) that are parallel to each other, at least two straight axial flexures (12, 12′; 22, 22′; 32, 32′), at least two flexures (16, 16′; 27, 27′; 36, 36′) and at least two bases (13, 13′; 23, 23′; 33, 33′), a first base carrying the movable element.
