Abstract

An impact screwdriver has an impact mechanism 17 which has a pressure chamber 35 which can be closed as a function of a reciprocating-action position of a reciprocating-action piston 33. The reciprocating-action piston is arranged within a rotation body 30. Located between the rotation body 30 and the reciprocating-action piston 33 are seal pairs 57,59; 58,60 which are arranged offset seen in the reciprocating-action direction of the reciprocating-action piston 33. In this way, the seal pairs 57,59; 58,60 achieve their respective sealing position in mutually offset reciprocating-action positions of the reciprocating-action piston 33, it being possible to reduce the size of the reciprocating-action position range of the reciprocating-action piston 33 as desired in which the pressure chamber 35 is sealed by the seal pairs 57,59; 58,60.
