Abstract: Disclosed herein is a three-stage hydraulic actuator. The three-stage hydraulic actuator includes a pressurizing chamber, a distribution chamber and an acceleration chamber. The pressurizing chamber has therein separated spaces respectively charged with compressed gas and compressed oil. The distribution chamber is provided to communicate with the pressurizing chamber and is charged with oil pressurized by the compressed oil charged into the pressurizing chamber. The acceleration chamber communicates with the distribution chamber through a distributing orifice. An acceleration piston is installed in the acceleration chamber and is moved forward when the pressurized oil is supplied from the distribution chamber to the acceleration chamber.
