Combustion-driven fastening tool

摘要

The tool has a combustion chamber (13) combusting an oxidant-fuel mixture, and a ventilator (41) generating a gas flow from an inlet opening (15) via the combustion chamber and toward an outlet opening (19). A combustion energy-driven drive unit (42) comprises an energy accumulator (47) and an energy storage unit (147) is formed as a clockwork drive which stores mechanical energy generated by a combustion energy for utilizing the combustion energy of the setting tool as drive energy for the ventilator. The ventilator is driven for a predetermined time with the use of an actuation switch (38).
