Abstract
A linear actuator (), comprising a threaded spindle () with a longitudinal extension along a longitudinal axis (X), the spindle () having a right hand thread () and a left hand thread (), both threads provided over a common longitudinal length of the spindle, the spindle () being adapted to be rotated by a driving device (). The linear actuator further comprises a first nut member () provided with a right hand thread () and a second nut member () provided with a left hand thread (). The first and the second nut members () are in threaded connection with the spindle () in such a way that rotation of the spindle provides opposite linear movement of the nut members () relative to each other along the longitudinal axis (X). Thereby, a linear actuator is provided with three parts that all move linearly relative to each other during rotation of the spindle.
