SYSTEM AND METHOD FOR IMPROVED ACTIVATION OF A HYDRAULIC DEVICE WITH RETRACTABLE PISTONS

摘要

The present invention concerns a system comprising a hydraulic circuit (C) comprising a hydraulic device (3) with retractable pistons, said system comprising an activation circuit for activating said hydraulic device (3) characterised in that it further comprises an accumulator (5) connected to said booster pump (2) and an activation valve (4) defining a threshold value of pressure in said accumulator (5), such that when said booster pump (2) is operating, and the pressure in the accumulator (5) is lower than said pressure threshold, said hydraulic device (3) is isolated from the booster pump (2), and when the pressure in the accumulator (5) reaches said pressure threshold value, the activation valve (4) connects said booster pump (2) and the accumulator (5) to the hydraulic device (3) via a boost line (21), and activates said device.
