Abstract:
The invention relates to a hand tool machine for placing a nail having a push button that can be activate by a user for placing a nail. A combustion chamber is provided, in which a mixture of combustible gas and air can be ignited. 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. The compressor has a fan wheel and an electric motor. At an operating speed of the electric motor, the fan wheel has a rotational speed of at least 2,000 rotations per second.
