An apparatus and a method for driving a fastening element into a base material, the apparatus having a bolt receptacle for the fastening element and a driving-in element which is moved toward the bolt receptacle between a starting position and a setting position, the apparatus having a cylindrical container which defines a cylinder axis, the driving-in element comprising a piston which is arranged in the cylindrical container such that it can be moved along the cylinder axis, with the result that the piston closes off a part volume of the cylindrical container, and a gas which is arranged in the closed-off part volume of the cylindrical container forms a gas spring, the cylindrical container being moved toward the bolt receptacle along the cylinder axis in order to tension the gas spring when the driving-in element is situated in the starting position.
An apparatus for driving a fastening element into a base material, the apparatus having a bolt receptacle for the fastening element and a driving-in element which can be moved toward the bolt receptacle between a starting position and a setting position, wherein the apparatus has a cylindrical container which defines a cylinder axis, wherein the driving-in element comprises a piston which is arranged in the cylindrical container such that it can be moved along the cylinder axis, with the result that the piston closes off a part volume of the cylindrical container, and a gas which is arranged in the closed-off part volume of the cylindrical container forms a gas spring, wherein the cylindrical container can be moved along the cylinder axis toward the bolt receptacle in order to tension the gas spring when the driving-in element is situated in the starting position.
