| 摘要 |
This invention relates to an actuator (2) comprising material adapted to contract when activated (4) within an inner sleeve assembly (24) contained by an outer sleeve assembly (22) that is cylindrical in shape. The inner sleeve (24) assembly further comprises a slide (16), an overstress spring (14), a sleeve (8), and a rebias spring (12). When the material adapted to contract (4) is activated, the contraction causes a rebias spring (12) to compress and a working end piece (18) moves causing desired movement. When the rebias (spring 12) expands, the actuator (2) returns to its normal resting position. In some embodiments a magnetic latch (44) can be paired with and activated by the actuator (2). |
