Abstract

Oppfinnelsen vedrører en styringsventil, en slaginnretning og en fremgangsmåte for styring av en arbeidssyklus for en slaginnretning. Slaginnretningen (1) benyttet for å bryte fjell innbefatter et slagelement (8) som blir styrt av en styringsventil (2). Styringsventilen innbefatter et styringselement (5) som er anordnet for å styre kanaler (7b) som fører til en arbeidstrykkoverflate (9) hos slagelementet (8). Bevegelsen av styringselementet til dets ytterposisjon er anordnet for å danne et lukket trykkrom hvor trykkmedium komprimeres og omdanner kinetisk energi fra styringselementet til trykkenergi. Trykkenergien blir omdannet på nytt til kinetisk energi og benyttet når styringselementet endrer sin retning.
