Abstract

L'invention concerne un dispositif d'actionnement successif d'au moins deux cylindres, comprenant : un premier conduit (2), équipé d'une première branche (21), conçue pour être raccordée à une chambre d'un premier cylindre (10), et une seconde branche (22), conçue pour être raccordée à une chambre d'un second cylindre (10) ; un second conduit (3), équipé d'une première branche (31), conçue pour être raccordée à l'autre chambre du premier cylindre (10), et une seconde branche (32), conçue pour être raccordée à l'autre chambre du second cylindre (11) ; une première soupape de commande (4), disposée le long de la deuxième branche (22) du premier conduit (2), qui est mobile entre une configuration d'ouverture, dans laquelle elle permet l'écoulement le long de la seconde branche (22) du premier conduit (2), et une configuration de fermeture, dans laquelle elle empêche l'écoulement le long de la seconde branche (22) du premier conduit (2) ; un premier étranglement (51), disposé le long de la première branche (31) du second conduit (3) ; un premier conduit pilote (41), qui relie la première soupape de commande (4) et la première branche (31) du second conduit au niveau d'un point intermédiaire entre le raccordement au premier cylindre (10) et le premier étranglement (51), et qui pilote la soupape de commande (4) pour l'amener dans la configuration fermée.
