Definitions
- the hydraulic actuator has a hydraulic cylinder with a piston arranged movably therein.
- the piston divides the hydraulic cylinder into two chambers and is connected at one end to the impact mechanism, so that a movement of the piston results in a movement of the impact work. If pressure is applied to the cylinder chamber facing away from the impact mechanism, the impact mechanism moves in the direction of the rotor. In the zero position, in particular, the cylinder chamber facing away from the impact mechanism is subjected to a pressure.
- valve threshold is adjusted such that the adaptive pressure relief valve is in the closed position when the pressure curve of the hydraulic actuator falls below the gradient threshold and the adaptive pressure relief valve is in the open position when the pressure curve of the hydraulic actuator exceeds the gradient threshold.
- the valve threshold is according to another embodiment in about 5- 10 bar, in particular 7 bar.
- the position of the zero position of the baffle 12 is determined by means of the determined by the path measuring device 22 position of the piston 20 at the time of pressure rise. If the slope of the pressure curve exceeds a certain gradient threshold, the zero position of the impact mechanism 12 is detected. The zero position is also detected, for example, when the adaptive pressure relief valve 26 is moved to the open position.
