Abstract

Oppfinnelsen angår en styreinnretning for en impulsgenererende innretning for å bevirke en sjokkbølge i et verktøy, idet den impulsgenererende irmretning omfatter et støtelement for å overføre en sjokkbølge til verktøyet, et mottrykkammer som virker mot støtelementet og en irmretning for å redusere et trykk i mottrykkammeret. Styreirmretningen omfatter en reguleringsanordning for å regulere reduksjonen av trykket i mottrykkammeret. Oppfirmelsen angår også en impulsgenererende irmretning.
