Abstract (en)
The electro-pneumatic hammer mechanism (21) and the motor and transmission unit (14) are accommodated inside a housing (12) with a tool (16) attached to the front (15). The hammer mechanism (21) comprises a piston (23) moved axially inside a cylinder (17). The motion is transferred to a hammer ram (25) hitting the striker (26) slightly off center (27) in order to move the tool (16) by the impact. The distance between the striking axis (22) and the point of impact (27) is selected in a specific relation to the length of the striker (26).
