The invention relates to a control device of an impact mechanism operable by means of a pressure media having an element for reversing the axial pressurization of the percussion piston and the return of the mediuni. In order to achieve a controllability of impact mechanisms by means of which the energy and the frequency of the moved percussion piston can be adjusted, it is provided according to the invention that 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. |
