Abstract

L'invention vise à créer un dispositif de lubrification pour lubrifier des pièces de machine qui soit de conception simple et qui permette d'obtenir une lubrification efficace des pièces de machine. À cet effet, le dispositif de lubrification selon l'invention comprend : un générateur d'aérosol qui produit un aérosol contenant un gaz porteur et un lubrifiant ; un dispositif d'amenée pour amener l'aérosol dans un espace intérieur de la machine dans lequel sont situées des pièces de machine à lubrifier ; un dispositif d'évacuation pour évacuer l'aérosol de l'espace intérieur de la machine ; un dispositif de commande pour commander le générateur d'aérosol et/ou le dispositif d'amenée et/ou le dispositif d'évacuation de telle sorte qu'une pression dans l'espace intérieur de la machine soit variable.
