Abstract (en)
[origin: EP2090405A1] The hammer (A) has a control body for controlling compressed air path of a compressed annular space for an impact or power stroke and a back stroke of an impact piston (1), and a sound absorber (6) with an air discharge. A valve body (4) and/or the control body are formed as a ring for opening and closing of air intakes (21, 31) for a pressurization of the piston in a cylinder (2) with compressed air in a tubular manner. The air intakes are arranged perpendicular to a movement axis (X) of the piston opposing each other in a direction in the cylinder and in a retaining or holding body (3).
