The fastening tool comprises a system for controlling the intake of a fuel into a combustion chamber (C), a source of fuel (30), a switch (14, 16) for igniting said fuel in said combustion chamber (C). A valve (60), normally closed, comprises an intake port (44) arranged for communicating with said source of fuel (30) and an exhaust port (50) arranged for communicating with said combustion chamber (C). The valve (60) is a piezoelectric injector arranged for pressurizing the fuel at the outlet thereof and thereby micronizing it. This invention applies well to nailing machines. |
