Abstract

La présente invention concerne un dispositif d'alimentation en huile sous pression destiné à un cylindre de serrage hydraulique (11) fonctionnant avec une pression de fonctionnement pB définie. Un flux d'huile de fuite important intervient dans le fonctionnement de serrage de ce cylindre de serrage et est reconduit au réservoir (32) d'une unité d'alimentation en pression (33) qui est également exploitée pour une alimentation en huile sous pression temporaire d'au moins un autre consommateur hydraulique. Ladite unité d'alimentation en pression comprend une première pompe (41) qui travaille de façon permanente à la charge d'un accumulateur de pression (52) servant de source de pression au consommateur (11; 61), ainsi qu'une seconde pompe (42) qui alimente un circuit de refroidissement dans le cadre d'un fonctionnement en circuit fermé presque sans puissance. Lorsque la pression de l'accumulateur chute en-dessous d'une valeur seuil pSU, un dispositif de charge d'accumulateur (41, 42, 59) permet de pouvoir recharger l'accumulateur à une pression pS, qui est nettement supérieure à la pression de fonctionnement pB. La première pompe (41) est conçue pour un débit qui couvre le flux d'huile de fuite lors du fonctionnement normal et qui maintient la pression de l'accumulateur à une valeur minimale pS à laquelle la pression de fonctionnement pB est stable. Le dispositif de charge d'accumulateur comprend une soupape de commutation (59) qui fait également passer la seconde pompe (42) en fonctionnement de charge de l'accumulateur lorsque la pression de l'accumulateur chute en-dessous de la valeur seuil inférieure de commutation pSU. La seconde pompe revient en fonctionnement en circuit fermé lorsque l'accumulateur (52) est de nouveau chargé à une valeur seuil de commutation pSO nettement supérieure.
