CONTROL OF THE WORKING FREQUENCY OF AN IMPACT MECHANISM |
| 摘要 |
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. |

1. A control device of an impact mechanism operable by a pressure medium, comprising:
a reversal element structured and arranged for reversing an axial pressurization of a percussion piston and a return of the pressure medium, wherein at least one channel switchable by the reversal part to a return line for the medium from the percussion hammer has at least one switchable element for flow control. |
