<p>The invention proposes a device (10) of the type including a cylindrical external reinforcement (16, 20) and an internal reinforcement (14) which is kept coaxial in the external reinforcement by an annular elastic connection block (18), characterised in that the connection block (18) divides the internal space into two main hydraulic chambers (32A, 32B), each one of which is delimited by a partition (34A, 34B) including at least one orifice (36A, 36B) which places it in communication with an associated auxiliary hydraulic chamber (38A, 38B) and in that the internal reinforcement (14) has two blocking members (68A, 68B), each of which is capable of blocking the communication orifice (36A, 36B) of one partition (34A, 34B) in order to isolate the corresponding main hydraulic chamber (32A, 32B) from its associated auxiliary chamber (38A, 38B) when the internal reinforcement (14) moves axially with respect to the external reinforcement in the corresponding direction. <IMAGE></p> |
