Abstract

Various embodiments of resettable pyrotechnically actuated poppet valve systems are disclosed herein. A resettable pyrotechnically actuated poppet valve system includes a pin assembly including a pin for engaging a moveable poppet closed against a valve seat and a shoulder for supporting the pin when a pyrotechnic device is disengaged. The system includes a valve body coupled to the pin assembly. The valve body includes an inlet and an outlet. The system includes an internal valve body disposed within the valve body. The moveable poppet is at least partially disposed within the internal valve body for contacting the valve seat. The pin maintains the poppet closed against the valve seat in a first position when the pyrotechnic device is disengaged and the poppet transitions to a second position by movement of the pin when the pyrotechnic device is engaged.
