  • Electric actuators having internal load apparatus
    Patent number: 8408518
    Abstract: Electric actuators having internal load apparatus are described herein. An example electric actuator having an internal load apparatus described herein includes a housing defining a cavity to receive a drive system and a drive shaft operatively coupled to the drive system. Rotation of the drive system in a first rotational direction causes the drive shaft to move in a first rectilinear direction and rotation of the drive system in a second rotational direction causes the drive shaft to move in a second rectilinear direction opposite the first rectilinear direction. A biasing element is operatively coupled to the drive system such that least a portion of the drive system moves axially toward the biasing element to deflect the biasing element when the drive shaft reaches an end of stroke position to provide a load to the drive shaft when electric power to the electric actuator is removed.
