Abstract
Presse hydraulique comportant un régulateur du débit de liquide sous pression qui alimente ses vérins. Ce régulateur permet de maintenir parallèles les plateaux de la presse sans avoir à renvoyer vers le réservoir d'alimentation le fluide sous pression excédentaire qui tend à les déséquilibrer, en provoquant l'allongement différencié des vérins hydrauliques qui les actionnent. Application aux grosses presses hydrauliques.
