Abstract:
The present invention relates to a hydraulic circuit comprising: an accumulator (11) a hydraulic device (1) a primary line (12) and a secondary line (13) connecting each said accumulator (11) to the hydraulic device (1), the primary line (12) comprising a restriction (14) and a primary distributor (15) adapted to selectively connect the hydraulic device (1) to the accumulator (11) or to a tank (R), the secondary line (13) comprising a secondary distributor (16) alternating between a first configuration in which it blocks the secondary line (13), and a second configuration in which it is passing, said secondary distributor (16) being controlled via the pressure within the primary line (12) downstream of the primary distributor (15) relative to the hydraulic accumulator (11), such that switching from the first to the second configuration of the secondary distributor (16) takes place only when the pressure in the primary line (12) reaches a threshold value.
