Abstract

A control arrangement for pneumatic hammers comprises a reciprocating rocking piston for actuating an impact cutter and a rocking slide for controlling the input of the compressed air and the output of the consumed air. After a predetermined control angle of the rocking slide a tension means effects a complete reversal of the rocking slide and the rocking piston.
