Device for transferring energy output from one pyrotechnic device to another

摘要

An energy transfer device (10) is provided that is capable of transferring the energy output from one pyrotechnic device (52) to another device (78) for initiating firing thereof. Device (10) comprises a device housing (12) in which a deformable device insert (14) is received. Device insert (14) comprises a central passageway (34) for transmitting the output from a pyrotechnic device (52), including energy, gasses, and/or solids, to another pyrotechnic device (78). The passageway (34) conducts the pyrotechnic device output to a precise location on the second pyrotechnic device (78) where firing is most effectively initiated. The energy transfer device (10) may be employed as a part of a tool (44) used in well completion operations.

1. An energy transfer device configured to transfer the energy output from a first pyrotechnic device to a second pyrotechnic device for initiating firing of the second pyrotechnic device, said energy transfer device comprising:
a device housing including a central bore extending therethrough, said housing including a housing forward section and a housing aft section; and a device insert carried by said housing within said bore, said insert comprising an insert forward section and an insert aft section and an axial passageway extending therethrough, said housing forward section and said insert forward section being configured for placement adjacent to and facing the first pyrotechnic device, and said housing aft section and said insert aft section being configured for placement adjacent to and facing the second pyrotechnic device, said insert forward section being deformable by the energy output from the first pyrotechnic device such that a constriction is formed in said passageway.
