Abstract (en)
[origin: WO2022207335A1] Disclosed is a driving tool comprising a hand-held housing in which a piston member is arranged for transmitting energy to a fastening element to be driven in in a driving direction, an especially replaceable propellant charge, a combustion chamber which is located between the propellant charge and the piston member and which extends about a central axis, and an actuator, by means of which the energy to be transmitted from the propellant charge to the piston member can be varied, wherein the combustion chamber has an internal thread and an especially cylindrical guiding portion, wherein the actuator is arranged in the combustion chamber and has an external thread meshing with the internal thread as well as a bearing for supporting the actuator in the guiding portion, wherein a gap between the external thread and the internal thread is wider than a gap between the bearing and the guiding portion.
