Abstract
The invention relates to a device comprising a first hydraulic apparatus (M1) and a second hydraulic apparatus (M2), the two motors (M1, M2) being connected by a first line (11) and a second line (12) enabling the admission or discharge of the oil in said motors (M1, M2), a booster pump (30), arranged between a tank and a booster line, the booster line communicating with at least one of said lines (11, 12), characterized in that the pump (30) is configured to be able to suck oil into the booster line in order to allow the decompression of said first and second lines (11, 12). The invention also relates to a method for evacuating a device of the type described above, in which the booster pump (30) is activated in suction mode in the booster line to enable the disengagement of the machines (M1, M2).
