ABSTRACT:
A pyrotechnic cutting device has a guiding housing in which there is arranged a part to be severed, which is fashioned so as to be severable at a cut point by a cutting tool having a cutting chisel. A pressure pulse generator containing a pyrotechnic driving charge is arranged in the cutting device for generating a pressure pulse to drive the cutting tool. In the guiding housing there is arranged, between the pressure pulse generator and the cutting tool, an impact capsule that can be accelerated by the pressure pulse of the triggered pressure pulse generator toward an inner thrust base of the cutting tool on the end of the cutting tool opposite to the cutting chisel. The cutting tool has its cutting chisel abutting the cut point before the impact capsule strikes the thrust base.
