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.

Abstract: A locking poppet valve that is reusable and can be pyrotechnically actuated includes an actuating mechanism and a valve assembly that are in fluid communication. A fluid channel traverses through a valve body and fluidly connects the actuating mechanism to a poppet valve positioned within the valve body. When the actuating mechanism is fired, a piston is displaced within an actuator housing, which in turn displaces hydraulic fluid within the actuator housing and the fluid channel. The displaced hydraulic fluid acts to push a valve spool along a valve stem, opening the poppet valve and allowing fluid to flow through the valve body. Additionally, the piston is held in a fired position by a locking mechanism, such that the poppet valve remains open. The poppet valve can be reset by disengaging the locking mechanism and allowing the hydraulic fluid to re-displace within the fluid channel and the actuator housing.
