ABSTRACT:
The actuator system comprises an actuator which includes a cylinder having a first end adapted to receive one or more gas generators and a second end having an opening therethrough. A piston having first and second ends defining the length thereof is movably mounted in the cylinder, dividing the cylinder into first and second variable volume chambers. The piston includes a piston rod attached thereto which extends out through the opening of the second end of the cylinder. An accumulator is coupled by a first passage system to the second variable volume chamber at substantially the second end of the cylinder. A first sequencing system provides for the charging of the accumulator and second chamber after a portion of the stroke. As the piston continues, the gas in the second chamber compresses, building up pressure and slowing the piston down. Near the end of the stroke, a second sequencing system vents the first chamber overboard and when the piston reaches the second end of the cylinder the gas in the accumlator is used to drive the piston back to the retracted position.
