Abstract
En ventilinnretning (V, 4) for styring av bevegelsen i et maskinhus (2) av et vekselvirkendeende slagstempel (3) i en slaganordning (1) for en fjellboremaskin med et første kammer (5) som kan trykksettes for å drive slagstempelet (3) fremover, og et andre kammer (8) som kan trykksettes for tilbakeføring av slagstempelet (3), der ventilinnretningen omfatter et ventilelement (20) som kan beveges frem og tilbake, der bevegelsen til dette styres i respons på posisjonen til et ventilelement (V) på slagstempelet i en ventilhusdel, ved å gjennom signalledningsmidler (22, 23, 24) trykksette et signalkammer (21) for aktivering av bevegelsen til ventilelementet. Nevnte signalledningsmidler omfatter i det minste to signalledningsdeler (23, 24) innrettet for hovedsakelig samtidig trykksetting gjennom samvirke mellom et korresponderende antall ventilstyrekanter (25, 26) på ventilelementet på slagstempelet og kanter (34, 35) i kontrollkammeret i maskinhuset. Oppfinnelsen angår også en slaganordning og en fjellboremaskin.
