摘要： An electropneumatic hammer of the type in which a driving piston is caused to undergo a reciprocating movement of translation under the action of an electric motor and a striking piston is driven by the driving piston, with the striking piston and the driving piston being mounted in a sleeve, the striking piston being disposed in such a manner as to impart a strike to a tool mounted in a tool-holder spindle, the driving piston being adapted to transmit, in the course of its reciprocating movements of translation, an alternating movement of rotation to the sleeve, the sleeve being connected to rotate with the tool through unidirectional connecting means, and means for imparting to the driving piston, in the course of its reciprocating movements of translation, an alternating movement of rotation about an axis parallel to its direction of translation.
