摘要： The invention relates to a setting tool for fastening elements, comprising a driving piston that can be driven by a primary drive, and comprising a secondary drive. In order to create a lightweight, handy setting tool, the primary drive is combined with the secondary drive in a hybrid drive system for the driving piston in such a way that the driving piston can be driven by both the primary drive and the secondary drive.

摘要： The invention relates to a handheld nail setting device comprising highly dynamic electromagnetic drive in the manner of a Thomson coil with soft-magnetic frame, comprising a first excitation coil (30) whose winding height is greater than its length, which hence is flat; a soft-magnetic frame in which the first excitation coil is arranged and against which it abuts, and which in in the manner of a pot magnet constitutes an open magnetic circuit which includes an outer region, a bottom and an inner region, and which is open on its end face, wherein the first excitation coil at least partly encloses the inner part of the frame; a short circuit armature preferably formed hollow cylindrical at least on its side facing the first excitation coil, which is movably mounted along an axis and which in its stroke starting position dips into the end-face opening of the frame and thereby at least partly encloses the inner part of the frame, wherein the frame entirely or predominantly is formed of a soft-magnetic composite material or one or more sheet stacks, which has a saturation flux density of at least 1.5 T and an effective specific electrical conductivity of not more than 106 S/m, and the first excitation coil and/or the frame include at least one means for strain relief, in particular in the form of an enclosure in order to at least partly absorb at least the radial forces occurring on the first excitation coil during an actuating operation vertically to the direction of movement, and wherein the Lorentz force acting on the short circuit armature is used to perform work.

摘要： The invention relates to a fuel-powered setting device for driving securing elements into a substrate, comprising at least one main combustion chamber for a fuel, a drive piston that can be driven out of the main combustion chamber in a setting direction by expandable gases, and a prechamber with which an ignition device is associated and in which a pressure acting on the main combustion chamber can build up prior to a fuel-air mixture being ignited in said main combustion chamber. To improve efficiency and/or functionality when driving in securing elements, the setting device can be operated in different energy classes by an energy adjustment.
