Abstract

This damping device comprises: PA1 two symmetrical jacks (10, 10'), extending respectively between each support member (8, 6) and the housing (4), each jack (10, 10') defining two chambers (24, 24', 26, 26') filled with a hydraulic fluid (16, 16'), PA1 two hydraulic lines (28, 28') establishing fluid communication between, on the one hand, the first chambers (24, 24') of the jacks and, on the other hand, the second chambers (26, 26') of the jacks, two branch lines (30, 30') opening into two accumulators (32, 32') containing a compressed gas, PA1 and means (34, 36, 40, 42) capable of providing a controlled flow rate of the fluid outside the said chambers (24, 24', 26, 26') and means (38, 44) capable of providing a controlled flow rate of the fluid to the accumulators. The intensity of damping of the transverse and hunting components can be independently adjusted.
