1. An actuator assembly, comprising:
- an actuation element adapted to receive an actuation drive force;
an electromechanical actuator adapted to be controllably energized and configured, upon being controllably energized, to supply a first drive force;
a hydraulic actuator connected to the electromechanical actuator and adapted to receive pressurized hydraulic fluid, the hydraulic actuator configured, upon receipt of pressurized hydraulic fluid, to supply a second drive force;
a link having a first end and a second end, the link rotationally connected to the electromechanical actuator at a position between the link first and second ends to receive the first drive force therefrom, the link first end rotationally connected to the hydraulic actuator to receive the second drive force therefrom, the link second end rotationally connected to the actuation element to supply the actuation drive force to the actuation element upon receipt, by the link, of the first drive force or the second drive force.

Abstract
A hybrid actuator assembly includes an actuator housing, an electromechanical actuator, and a hydraulic actuator. The electromechanical actuator is disposed at least partially within the actuator housing and is adapted to be controllably energized. The electromechanical actuator is configured, upon being controllably energized, to supply a first drive force. The hydraulic actuator is disposed at least partially within the actuator housing and is adapted to receive pressurized hydraulic fluid. The hydraulic actuator is configured, upon receipt of pressurized hydraulic fluid, to supply a second drive force.
