An energy transfer device () is provided that is capable of transferring the energy output from one pyrotechnic device () to another device () for initiating firing thereof. Device () comprises a device housing () in which a deformable device insert () is received. Device insert () comprises a central passageway () for transmitting the output from a pyrotechnic device (), including energy, gasses, and/or solids, to another pyrotechnic device (). The passageway () conducts the pyrotechnic device output to a precise location on the second pyrotechnic device () where firing is most effectively initiated. The energy transfer device () may be employed as a part of a tool () used in well completion operations.

Energy transfer device

A vented pyrotechnic device is provided that hermetically seals the pyrotechnic material contained therein under ambient storage conditions, but vents upon exposure to elevated-temperature conditions at or below the outgassing temperature for the pyrotechnic material. The vent passage communicating the chamber containing the pyrotechnic material with the exterior of the device is initially sealed at ambient storage conditions by a temperature-sensitive material. When exposed to a predetermined temperature condition, the temperature-sensitive material undergoes a physical change unblocking the passage and permitting venting of off gases produced by the pyrotechnic material.
