Title
(DE) HYDRAULISCHE STELLEINRICHTUNG
(EN) HYDRAULIC ADJUSTING DEVICE
(FR) DISPOSITIF DE COMMANDE HYDRAULIQUE
Abstract
(DE)
Offenbart ist eine hydraulische Stelleinrichtung, insbesondere zur Verwendung in einer Energieanlage, insbesondere einer Windenergieanlage, die eine Stellfunktion für einen Arbeits- und für einen Sonderbetrieb aufweist. Ein dafür vorgesehener doppeltwirkender Stellzylinder (2; 2'; 2") ist hierfür mit einem Arbeitsdruckmittel beaufschlagbar und zur Erfüllung der Stellfunktion im Sonderbetrieb mit einem Druckmittelspeicher verbindbar (6), der ein vom Arbeitsdruckmittel getrenntes Druckgas aufweist. Dabei weist der Stellzylinder einen insbesondere für die Stellfunktion des Sonderbetriebes vorgesehenen Arbeitsraum (30; 30'; 30") auf, dessen Kolbenfläche mit einer insbesondere für den Arbeitsbetrieb vorgesehenen Kolbenanordnung des Stellzylinders gekoppelt ist oder mit dieser Kolbenanordnung koppelbar ist.
(EN)
The invention relates to a hydraulic adjusting device, in particular for use in a power plant, in particular a wind power plant, which has an adjusting function for a working operation and for a special operation. To this end, a double-acting adjusting cylinder (2; 2'; 2'') provided for this purpose can be pressurized with a working pressure medium and, in order to satisfy the adjusting function in the special operation, can be connected to a pressure medium reservoir (6), which has a pressurized gas isolated from the working pressure medium. The adjusting cylinder has a working chamber (30; 30'; 30'') provided in particular for the adjusting function of the special operation, the piston area of which is coupled to a piston arrangement of the adjusting cylinder that is in particular provided for the working operation or can be coupled to said piston arrangement.
(FR)
L'invention concerne un dispositif de commande hydraulique, à utiliser notamment dans une centrale à énergie, en particulier dans une éolienne, présentant une fonction de commande pour un mode de travail et pour un mode spécial. Ce dispositif comprend un vérin de commande (2 ; 2' ; 2") à double effet qui peut être soumis à l'action d'un fluide de travail sous pression et qui peut être relié à un réservoir de fluide sous pression (6) pour remplir la fonction de commande en mode spécial, ce réservoir contenant un gaz sous pression différent du fluide de travail sous pression. Le vérin de commande présente une chambre de travail (30 ; 30' ; 30") prévue en particulier pour la fonction de commande du mode spécial, la surface de piston de cette chambre de travail étant ou pouvant être couplée à un ensemble piston du vérin de commande prévu en particulier pour le mode de travail.
