Abstract
A linear actuator includes an oscillating component that includes a threaded element, a traveler located inside the oscillating component that includes a mating threaded element, and a directional clutch located between the oscillating component and the traveler. The oscillating component is configured to be coupled to a source of oscillating motion and to be driven by the source of oscillating motion to cause oscillatory movements of the oscillating component. The directional clutch is configured to cause the oscillating component to drive the traveler in the first rotational direction when the oscillating component is rotated in the first rotational direction and to allow the oscillating component to slip by the traveler when the oscillating component is rotated in the second rotational direction. The threaded element and the mating threaded element are engaged such that rotational movement of the traveler in the first rotational direction causes linear movement of the traveler.
