摘要: An impulse generator (1) for a percussive tool includes chamber (3) receiving liquid volume and an piston (4) which is arranged transferring pressure pulses in the into stress wave tool. The adapted with respect to its shape such that it forms resonance forming at least one antinode (11,15,17) inside chamber. invention also concerns method hydraulic
