Abstract (en)

[origin: EP1542323A2] The device has at least two main electrodes in a pressure-tight housing and at least one auxiliary ignition electrode and a unit for reducing the spark gap response voltage connected to a main electrode and the auxiliary ignition electrode. The unit for reducing the spark gap response voltage consists of a series circuit of a voltage switching element, an impedance and an isolation section fully integrated into the pressure-tight housing and arranged outside the spark gap combustion chamber.
