In the combustion chamber, a piston is arranged in a movable manner in order to be accelerated by the combustion gases in the direction of placement. In the direction of placement, the piston has a punch protruding from the piston for driving the nail. A compressor compresses the air in the combustion chamber prior to igniting.
