Definitions

  • the coil consists of two cascaded, covering, lying in parallel areas layers, the current and winding direction of the two layers of the coil are matched to each other in terms of strengthening their magnetic field, and that the the membrane has the smaller potential difference position of the coil of the membrane is arranged directly opposite.
  • the invention takes advantage of the fact that the high voltage drops across the coil, which in the case of a two-layer coil has the result that there is a maximum potential difference between at least one layer of the coil and the membrane, which is less than that for the same amount of High voltage between the membrane and maximum potential difference present in a single-layer coil.
  • the coil builds due to the fact that its two layers are connected one behind the other and lying in a covering manner in parallel areas, the current and winding directions of the two layers being matched to one another in the sense of strengthening their magnetic field, with the same amount of high voltage and the same coil diameter stronger magnetic field than a single-layer coil, which induces larger eddy currents in the membrane and builds a stronger magnetic opposing field, which ultimately results in the formation of stronger shock waves in the liquid-filled space.
  • the invention albeit partially or completely dispensing with an improved high-voltage strength - allows a larger electrical energy to be converted into impulse energy or, with the same electrical energy, to realize shorter rise times of the shock wave, since that in the high voltage supply capacitor can be charged to a higher charging voltage than a shock wave generator with a single-layer coil.
  • the capacitor can either give off a larger energy, which increases with the square of the charging voltage, or its capacity can be reduced with the same available energy, as a result of which the resonant circuit formed by the coil and the capacitor has a higher natural frequency, which leads to a shorter rise time of the current flowing through the coil and thus leads to a shorter rise time of the shock wave, which is quite desirable when crushing concrements.
