要約
(EN)
A hydraulic device (1) wherein an operating cylinder (2) and an acceleration cylinder (3) are equipped with pistons (5, 12), rods (6, 13), and tubes (4, 11), with the tubes (4, 11) partitioned into rod-side compartments (8, 15) and bottom-side compartments (7, 14) by means of the pistons (5, 12). When there is no load and the rod (6) of the operating cylinder (2) extends, a circuit is created wherein the oil in the bottom-side compartment (14) of the acceleration cylinder (3) is supplied to the bottom-side compartment (7) of the operating cylinder (2) through a bottom line (27), and when there is a load and the rod (6) of the operating cylinder (2) extends, a circuit is created wherein the oil supplied to the bottom line (27) without passing through the acceleration cylinder (3) is supplied to the bottom-side compartment (7) of the operating cylinder (2). Switching from the no-load circuit to the load circuit is performed on the basis of the detection of the pressure in the bottom line (27).
(FR)
L'invention concerne un dispositif hydraulique (1) dans lequel un cylindre de commande (2) et un cylindre d'accélération (3) sont équipés de pistons (5, 12), de tiges, (6, 13) et de tubes (4, 11) et où les tubes (4, 11) sont divisés en compartiments de côté de tige (8, 15) et en compartiments de côté de fond (7, 14) au moyen des pistons (5, 12). Lorsqu'il n'y a pas de charge et que la tige (6) du cylindre de commande (2) s'étend, un circuit est créé dans lequel l'huile dans le compartiment de côté de fond (14) du cylindre d'accélération (3) est alimentée au compartiment de côté de fond (7) du cylindre de commande (2) par une ligne inférieure (27), et lorsqu'il y a une charge et que la tige (6) du cylindre de commande (2) s'étend, un circuit est créé dans lequel l'huile alimentée à la ligne inférieure (27) sans passer à travers le cylindre d'accélération (3) est fournie au compartiment de côté de fond (7) du cylindre de commande (2). La commutation du circuit sans charge au circuit de charge est effectuée par la détection de la pression dans la ligne inférieure (27).

 油圧装置(1)であって、作動シリンダ(2)及び増速シリンダ(3)は、ピストン(5,12)とロッド(6,13)とチューブ(4,11)とを備えており、チューブ(4,11)は、ピストン(5,12)を介してロッド側区画(8,15)とボトム側区画(7,14)とに区画され、無負荷時に作動シリンダ(2)のロッド(6)を伸長する際は、増速シリンダ(3)のボトム側区画(14)の油が、ボトムライン(27)を経て、作動シリンダ(3)のボトム側区画(7)に供給される回路となり、負荷時に作動シリンダ(3)のロッド(13)を伸長する際は、ボトムライン(27)に増速シリンダ(3)を介さずに供給された油が、作動シリンダ(2)のボトム側区画(7)に供給される回路となり、無負荷時の回路から負荷時の回路への切り換えは、ボトムライン(27)の圧力検知により行われる。
