Abstract
An actuator including a motor, clutch, gear train, solenoid, clock spring, and air brake is provided. The motor is configured to drive a control valve. The clutch is operably coupled to the motor and configured to prevent the motor from transferring more than a predetermined amount of torque. The gear train is operably coupled to the clutch and configured to receive the predetermined amount of torque from the motor. The solenoid is operably coupled to the gear train and configured to disengage one of the gears in the gear train from adjacent gears. The clock spring is operably coupled to another of the gears in the gear train, configured to store mechanical energy supplied by the motor, and configured to drive the control valve. The air brake is operably coupled to the gear train and configured to dissipate a portion of the mechanical energy released by the clock spring.
