Abstract

L'invention concerne un entraînement hydraulique (1) d'un enrouleur (2) destiné à une voile (7) d'un engin à voile (3). L'entraînement (1) est relié à un réservoir de fluide (10), destiné à un fluide hydraulique, au moyen d'une liaison par conduits constituée d'un conduit d'alimentation (8) et d'un conduit de retour (9) et peut fonctionner de manière à servir d'entraînement (1) lorsque la voile (7) est enroulée mais de pompe pour le fluide hydraulique lorsque la voile (7) est déroulé. Un élément de séparation (11), conçu comme un piston, est disposé de manière mobile en translation dans le réservoir de fluide (10), lequel élément de séparation subdivise le réservoir de fluide (10) en deux chambres variables (12, 13). Selon l'invention, l'élément de séparation (11) est précontraint par un ressort (14) en direction d'une position de réservoir réduisant le volume de la seconde chambre (13) et augmentant en même temps le volume de la première chambre (12) de sorte que le volume de fluide, amené lorsque la voile (7) est déroulée, est amené dans la chambre (12) en s'opposant à cette force de rappel (F). Selon l'invention, une partie de la force agissant lors de l'augmentation de la surface de la voile (7) est stockée de manière simple par l'élément à ressort (14) et peut ainsi être utilisée pour enrouler la voile (7). Le coût d'installation de l'entraînement (1) selon l'invention est très inférieur à celui d'un entraînement relié à une pompe entraînée par un moteur électrique et élimine également une alimentation en énergie.
