ABSTRACT:
A linear actuator comprising a hollow first cylindrical shaft with helical threads on its exterior surface and helical threads of opposite pitch on its interior surface and a second cylindrical shaft having an exterior surface with helical threads of the same pitch as on the interior surface of the first shaft and a motor for rotating the first shaft and relative to the second shaft end a base member. The second cylindrical shaft is coaxial with and adjacent the first shaft surface and its threads engage the threads of the first interior surface. Helical threads on the base member of the same pitch as the first shaft exterior surface threads are coaxial with and adjacent the first shaft exterior surface and engage the helical threads of the exterior surface of the first cylindrical shaft.
