Abstract

Regulator for en slaghammer som omfatter en hoveddel med en sentral boring (3) og et slagstempel (4) inne i denne. Konsentrisk med slaghammeren (4) og inne i boringen er anordnet to innbyrdes aksialt forskjøvne elementer (17, 18) som en deformerbar rondell eller ringskive (19) er anordnet mellom. Det ene element (17) er ubevegelig, mens det andre (18) er forskyvbart frem og tilbake inne i boringen (3) og forskyves i retning mot det ubevegelige element (17) under virkningen av trykket av slaghammerens tilførte hydrauliske fluid. Dette trykk virker på en flate av dette element (18), nemlig en flate som er vendt motsatt retningen mot det ubevegelige element (17). Forskyvningen av elementet (18) gir en deformasjon av den elastiske ringskive (19) slik at det dannes en forbindelse med varierbart tverrsnitt i kanalen (1 5) for retur av hydraulisk fluid mot reservoaret, eller i en krets som leder en del av tilførselsfluidet til utløpet, slik at fluidtrykket kan reguleres på inngangen.
