Ignition device for igniting a foil cartridge in an explosion-operated power tool

摘要

An ignition device for igniting a foil cartridge (10) in an explosion-operated power tool includes an electrical insulator (24) arranged in the support (8), a pin-shaped electrode (25) located in the electrical insulator and having a tip (30) that communicates with surrounding environment via a channel (32) formed in the electrical insulator (24) and extending in a longitudinal direction of the pin-shaped electrode (25) and an electrically conducting annular electrode (27) supported on the support (8) in a region of the channel (32) and tightly surrounding the insulator (24), leaving the channel (32) free.
