Claims (6)

1. En hydraulisk slagmaskin, till vilken hör en stonune (1) med hydraulkanaler och -ventiler (8,16), och i vilken slagmaskin finns en gasfylld, hydraulisk tryckackumulator (2) för lagring av den slagenergi, som accelererar kolven (3) till ett slag mot verktyget (4), kännetecknad därav, att det i slagmaskinen finns en separat, medelst en ventil (16) frän den högtyrycksbelagda driftskretsen (30) avskild och frän driftskretsen (30) oberoende lägtrycksbelagd hydraulkrets (5), som fylls innan arbetscykelns inledning och som tillsammans med ventilen (16) halier maximi- och minimitrycket i tryck-ackumulatorns (2) vätskeutrymme (29) konstanta.
2. Slagmaskin enligt patentkravet 1, kännetecknad därav, att den som energiförräd fungerande hydrauliska tryckackumulatorn (2) är indirekt kopplad till en tryckledning (6) som driver maskinen.
3. Slagmaskin enligt patentkravet 1 eller 2, kännetecknad därav, att den som energiförräd fungerande hydrauliska tryckackumulatorn (2) är med den frän driftkretsen (30) oberoende ventilen (16) kopplad till driftkretsen (30).
4. Slagmaskin enligt nägot av patentkraven 1-3, kännetecknad därav, att huvudventilen (8) styrs av kolvens (3) position.
5. Slagmaskin enligt nägot av patentkraven 1-4, kännetecknad därav, att den hydrauliska tryckackumulatorn (2) alltid är i direkt förbindelse med kolvens överyta (9), varvid tryckackumulatorn tar tillvara den frän verktyget (4) tillbakastudsande kolvens (3) rörelse-energi.
6. Slagmaskin enligt nägot av patentkraven 1-5, kännetecknad därav, att koiven (3) da den stannar vid slutet av sin returrörelse överläter sin rörelse-energi tili den hydrauliska tryckackumulatorn (2).
