  • the object of the invention is to improve the effectiveness and/or the functionality when driving in fasteners with a combustion-powered setting tool with at least one main combustion chamber for one fuel, with a driving piston that can be driven in a setting direction via expandable gases from the main combustion chamber, and with an antechamber , which is assigned an ignition device and in which a pressure acting on the main combustion chamber can be built up before the ignition of a fuel-air mixture in the main combustion chamber.
  • the task is for a combustion-powered setting tool for driving fasteners into a substrate, with at least one main combustion chamber for a fuel, with a driving piston that can be driven in a setting direction via expandable gases from the main combustion chamber, and with an antechamber that is assigned an ignition device and in which a pressure acting on the main combustion chamber can be built up before the ignition of a fuel-air mixture in the main combustion chamber, solved in that the pre-chamber is assigned a valve device via which a maximum charging pressure in the pre-chamber can be varied in order to to adjust the setting energy provided for a setting process.
  • the valve device is, for example, a blow-off valve that is assigned to the antechamber.
  • this provides the advantage, among other things, that the setting energy can be adjusted more precisely. This is due, for example, to the fact that less pressure is built up in the pre-chamber during pre-combustion than in the main combustion chamber during main combustion. With the valve opening duration being the same, less is blown off via the blow-off valve assigned to the antechamber. In addition, the requirements for the switching times of the blow-off valve assigned to the antechamber are not as high, since the pre-combustion takes place more slowly than that major burn. For example, the pre-combustion lasts about four times as long as the main combustion.
  • a preferred exemplary embodiment of the combustion-powered setting tool is characterized in that the valve device is designed as a manually operated blow-off valve.
  • the blow-off valve can, for example, be actuated directly by hand or via an adjusting element, for example an adjusting wheel.

  • the valve device is advantageously designed as a controllable pressure relief valve.
  • a further preferred exemplary embodiment of the combustion-powered setting tool is characterized in that the valve device is electrically controlled by an electronic controller.
  • the control can take place via an electrical signal that results from an evaluation of a previous setting.
  • a further preferred exemplary embodiment of the combustion-powered setting tool is characterized in that the electronic control comprises a user interface.
  • a user of the setting device can advantageously set the energy for a subsequent setting digitally via the user interface. This can improve the quality of the subsequent setting.
  • a further preferred exemplary embodiment of the combustion-powered setting tool is characterized in that the valve device is connected in terms of control to a sensor device which comprises at least one sensor. State variables that are not constant when the setting tool is operated can be detected with the sensor device. These are, for example, temperatures or pressures that change depending on location or time.
  • a further preferred exemplary embodiment of the combustion-powered setting tool is characterized in that the sensor device comprises at least one temperature sensor, a pressure sensor, an acceleration sensor, a speed sensor and/or a sensor for detecting a height at which the setting tool is currently located.
  • the sensor for detecting an altitude can also be referred to as an altimeter.

  • a further preferred exemplary embodiment of the combustion-powered setting tool is characterized in that the main combustion chamber is assigned a valve device, via which a maximum pressure in the main combustion chamber can be limited.
  • the valve device is preferably designed as a controllable pressure relief valve. A desired maximum pressure during combustion in the main combustion chamber can advantageously be set with the valve device.
  • a further preferred exemplary embodiment of the combustion-powered setting tool is characterized in that the setting tool comprises a control device, via which the setting energy is determined from a differential pressure between the main combustion chamber and an ambient pressure.

Due to the control pressure connection, the control device is controlled with the main combustion chamber pressure during operation of the setting tool. When the pressure in the main combustion chamber reaches a certain pressure level, the at least one passage opening in the antechamber is automatically opened.
  • the invention also relates to a method for operating a combustion-powered setting tool as described above.
  • Gas cartridges for example, are used to provide the setting energy. Due to the pre-combustion in the antechamber before the actual main combustion, the setting energy provided by the setting tool can be increased without the size of the setting tool increasing. Combustion at increased pressure can increase the efficiency of the setting tool, since the combustion processes run more efficiently at higher pressure.
