Abstract

The percussion drilling machine has a housing (1) into which a reciprocating percussion head (2) is inserted. The percussion head (2) forms a front working chamber (4) in the housing (1) and has a hollow space which forms the rear working chamber (3), which is connected to the front working chamber (4) via slots (5). By means of compressed air fed to the percussion head (2) via a connection piece (6), the percussion head (2) performs a reciprocating movement and exerts blows on the housing (1). When the hose (17) supplying the compressed air is pulled, a bush (11) provided with slots (13) controls the change-over of the drilling machine from forward motion to reverse motion. <IMAGE>
