Abstract
Control device of an impact mechanism operable by a pressure media having an element for reversing the axial pressurization of the percussion piston and the return of the medium. In order to achieve a controllability of impact mechanisms by which the energy and the frequency of the moved percussion piston can be adjusted, at least one channel switchable by the reversal as a return line for the medium from the percussion hammer has at least one switchable element for the flow control.
