A pyrotechnic actuator comprising a cylindrical housing, both ends of which are open, an electric ignition device disposed to block an opening portion at one end of the cylindrical housing, and a piston and a piston rod, inserted into the cylindrical housing to be capable of an axial motion, the cylindrical housing having in a peripheral surface thereof a gas discharge port, the gas discharge port being blocked by the piston prior to activation and opened by the motion of the piston after activation.
A pyrotechnic actuator, comprising:
- a cylindrical housing including a first end and a second end opposite to the first end;
- an electric ignition device provided in the first end;
- an opening provided in the second end;
- a piston and a piston rod provided within the cylindrical housing to be capable of sliding movement in an axial direction of the cylindrical housing such that the piston rod is engagement with the opening;
- and
- a gas discharge port formed in a peripheral portion of the cylindrical housing, the gas discharge port being closed by the piston prior to activation and open after activation.
