Abstract

Foreliggende oppfinnelse er relatert til en fremgangsmåte for å kontrollere en trykkfluidoperert perkusjonsinnretning innbefattende et arbeidskammer (3) for trykkfiuid og i arbeidskammeret (3) ettransmisjonsstempel (4) installert bevegelig med hensyn til dette, slik at det muliggjør et verktøy (5) installert i perkusjonsinnretningen å bli trykket mot et materiale som blir brukt for å generere en stresspuls, og til en perkusjonsinnretning. Fremgangsmåten innbefatter justering av lengden av stresspulsen ved å justere tiden under hvilket trykk påvirker transmisjonsstempelet (4). Perkusjonsinnretningen innbefatter et justeringselement (14) og justeringsinnretning for å justere påvirkningstiden til trykket fra trykkfiuidet som blir matet via en kontrollventil (8), og som påvirker transmisjonsstempelet (4).
