Abstract
An electronically controlled actuator which compresses a fluid thereby storing potential energy as it transitions from a first to a second position is disclosed. The compressed fluid exerts a high force on the actuator and the potential energy is recovered in returning the actuator to the first position. A latching arrangement automatically locks the actuator shaft as it reaches the second position. The latching arrangement is selectively unlocked at the prescribed time to allow the stored potential energy to return the actuator to the first position.
