CYLINDRICAL ACTUATOR SUBASSEMBLY WITH FLEXURE-BASED LINEAR GUIDANCE MECHANISM

摘要

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.
