- Hand-held driving devices with propellant charge are known from the prior art, in which after ignition of a pyrotechnic charge, the resulting fuel gases expand in a combustion chamber. As a result, a piston is accelerated as energy transfer means and drives a fastener into a workpiece. Basically, the most optimized, residue-free and reproducible burning of the charge is desired. It should be noted that the charge usually includes particles such as powder grains, fibers or the like, which are initially driven after ignition in front of a flame front ago.
- Combustion chamber is separated by means of a perforated disc in an upper part of the chamber and a lower chamber part.
- Powder grains of the propellant charge are larger than the holes of the disc.
- the powder grains are first accelerated in a central discharge area on the perforated portions of the cutting wheel, where they are retained due to the dimensioning of the holes of the cutting wheel, so that a combustion of the powder grains takes place predominantly in the upper part of the chamber.
- Fig. 10 is a

- a blow-off channel in the sense of the invention is understood to mean a duct by means of which the combustion gases of the propellant charge are discharged into the environment or into another large volume, for example a gas reservoir for a piston return.
- the piston member is defined by the same slide, which controls the blower, defined against a rearmost position. In such a position, a larger output volume of the combustion chamber is created compared to a rearmost position of the piston member. Furthermore, the concept of the remaining acceleration path of the piston member is shortened by the idea.
- a driving energy is understood to mean the kinetic energy of the piston member impinging on a given fastening means for a given propellant charge. Given these boundary conditions, it is possible by the actuator to adjust the resulting driving energy for the fastener adjustably.
- a piston member according to the invention is any means which is acted upon by the ignition of the charge with kinetic energy, wherein the kinetic energy is ultimately transferred to the fastening means. Often the piston member is designed as a particular cylindrical piston.
