Abstract

Dispositif de mise sous pression automatique d'un mécanisme tel qu'une boîte de vitesses ou un régulateur de vitesse constante. Il comporte une pompe volumétrique 14 destinée à établir une certaine pression dans une enceinte ou boîte 10 contenant le mécanisme. A cet effet, la pompe 14 peut refouler dans la boîte 10 l'air de l'atmosphère arrivant par un conduit 36 lorsqu'une soupape 12 est placée dans une première position qui dépend de la différence entre la pression de la boîte 10 et la pression atmosphérique. Un étranglement 16 assure un écoulement constant de lubrifiant vers la soupape 14 et la boîte 10. Domaine d'application: boîtes de vitesses, régulateurs de vitesse, etc
