Abstract

Et hydraulisk slagverktøy for en boresammenstilling er omtalt. I noen utførelser innbefatter det hydrauliske slagverktøy et rørformet hus, en spindel anbrakt i huset, et ringrom mellom spindelen og huset, og en trykkfrigjøringsmekanisme anbrakt i ringrommet. Trykkfrigjøringsmekanismen avdeler generelt ringrommet i første og andre partier. Trykkfrigjøringsmekanismen innbefatter først og andre ringformede deler i inngrep med hverandre når trykket i det andre ringromspartiet er mindre enn en forhåndsbestemt verdi og en fluidstrømningsbane mellom de første og andre ringromspartier. Fluidstrømningsbanen har en første størrelse når trykket i det andre ringromspartiet er mindre enn den forhåndsbestemte verdi, og en andre størrelse som er større enn den første størrelse når trykket i det andre ringromspartiet blir lik med eller større enn den forhåndsbestemte verdi.
