Abstract

Source de pression hydraulique pour amplificateurs hydrauliques. Elle comprend une pompe hydraulique 6, un passage d'huile de haute pression 7 comportant une partie reliant un orifice de sortie de la pompe 6 et un orifice d'entrée Ba d'un amplificateur hydraulique B, et un régulateur 11 pour réguler une pression délivrée par la pompe 6 et transmettre cette pression à l'amplificateur B. Le régulateur se présente sous la forme d'une valve de réduction proportionnelle 11 capable de réduire la pression délivrée par la pompe 6 dans un rapport de réduction prédéterminé et de transmettre une pression réduite à l'amplificateur B, la valve 11 ayant un piston 16 qui peut se déplacer dans un sens de retrait d'une course d'une longueur telle qu'elle permet au piston 16 de reculer au-delà d'une position de fermeture de valve pour augmenter le volume d'une chambre hydraulique de sortie 18.
