Abstract
Ce dispositif comprend un vérin de levage 15, 16 monté, par exemple, entre le châssis d'une moissonneuse-batteuse et son tablier, lequel s'appuie sur le sol par un faible poids résiduel. Un accumulateur 61 assure la suspension du tablier. Une soupape limitatrice de pression 19 qui influence la pression de service dans le vérin 15 est montée dans une conduite de travail 18, menant à la bâche 21, d'où part, en amont de la soupape 19, une liaison transversale 57 contenant un clapet antiretour 58 et aboutissant sur le vérin 15. Il est ainsi possible, non seulement d'éviter le vidage complet de l'accumulateur 61 lors de l'abaissement du tablier, mais aussi d'obtenir des abaissements rapides et une plus grande étanchéité du dispositif.
