Claims (9)

1. Et hydraulisk system (1) omfattende en gruppe af mindst to ventiler (2a, 2b, 2c) forbundet til en samleskinne (8), hver af nævnte ventiler (2a, 2b, 2c) omfatter et ventilhus (4a, 4b, 4c), et ventilelement (3a, 3b, 3c) og en primær hukommelse (9a, 9b, 9c) til lagring af et sæt af parametre af ventilen (2a, 2b, 2c), hvor hver ventil (2a, 2b, 2c) omfatter mindst en trykforsyningsport (P), en tankport (T), en eller flere arbejdsporte (A, B) og en sekundær hukommelse (10a, 10b, 10c) til lagring af nævnte sæt af parametre af en forskellig ventil (2a, 2b, 2c) af nævnte gruppe, hvor positionen af ventilelementet (3a, 3b, 3c) i dets ventilhus (4a, 4b, 4c) bestemmer en strøm af hydraulikvæske fra trykforsyningsporten (P) til en af arbejdsportene (A, B) og fra den anden arbejdsport (Β, A) til tankporten, hvor hver ventil (2a, 2b, 2c) omfatter en unik adresse (7a, 7c, 7c) i nævnte gruppe af ventiler og der findes mindst en reservedelsventil med en adresse forskellig fra alle adresserne (7a, 7b, 7c) i nævnte gruppe.

8. Fremgangsmåden ifølge kravene 6 til 7, kendetegnet ved, at en første ventil omfattende en sekundær hukommelse (10a, 10b, 10c) af en anden ventil undersøger om en anden ventil er til rådighed på samleskinnen (8) og, hvis den ikke er tilgængelig, men en reservedelsventil er til rådighed opdateres den primære hukommelse (9a, 9b, 9c) af nævnte reservedelsventil af den sekundære hukommelse (10a, 10b, 10c) af nævnte første ventil.
