Claims (8)
1. Rotorbremse til et vindenergianlæg, som har en første og en anden trykreduktionsventil (28, 38), ved hjælp af hvilke en bremsecylinder (36) med et første og et andet hydrauliktryk (pb, ph) kan påvirkes, og som har en omkoblingsinstallation, som kan skifte mellem det første og andet hydrauliktryk (pb, ph), og hvor omkoblingsinstallationen har en trykbegrænserventil (24) og et tryklager (32), som med en tidsmæssig forsinkelse kan omkoble en omkoblingsventil (18) mellem det første og andet tryk (ρε, ph), kendetegnet ved, at tryklageret (32) via trykbegrænserventilen (14) og en strømreguleringsventil (24) kan forbindes med en tank (26).
2. Rotorbremse ifølge krav 1, kendetegnet ved, at trykbegrænserventilen (14) kan spærre, når trykværdien ligger under en første trykspærreværdi.
3. Rotorbremse ifølge krav 2, kendetegnet ved, at omkoblingsventilen (18) kan aktiveres hydraulisk, når det ved dens hydrauliske aktivering (16) gælder, at en trykværdi falder under en anden trykspærreværdi.
4. Rotorbremse ifølge krav 3, kendetegnet ved, at den anden trykspærreværdi er mindre end eller lig med den første trykspærreværdi.
5. Rotorbremse ifølge et af kravene 1 til 4, kendetegnet ved, at tryklageret (32) er forbundet med begge trykreduktionsventiler (28, 38).
6. Rotorbremse ifølge et af kravene 1 til 5, kendetegnet ved, at den har en første trykafbryder (48) til tryklageret (32), og som overvåger den laveste trykværdi ved tryklageret (32).
7. Rotorbremse ifølge et af kravene 1 til 6, kendetegnet ved, at der findes en anden trykafbryder (50) til hydraulisk aktivering (16) ved omkoblingsventilen (18).
8. Rotorbremse ifølge et af kravene 1 til 7, kendetegnet ved, at rotorbremsen er udformet som en aktiv bremse, som med stigende hydrauliktryk kan tilvejebringe et stigende bremsemoment.
