Abstract

Une pompe hydraulique peut éviter la rupture à haute pression sans nécessiter une soupape de dépression séparée. Un logement a un côté corps et un côté couvercle qui sont séparés par une surface perpendiculaire à un axe de rotation d'un arbre de pompe hydraulique. Le logement côté couvercle est mis en contact étanche à l'huile avec le logement côté corps par un ressort. Le contact entre le logement côté corps et le logement côté couvercle est maintenu à une pression prédéterminée correspondant à une pression hydraulique de pompe maximale admissible.
