A rubber sleeve spring of two independently made parts each including two supporting sleeves one radially surrounding another, as well as a spring body of rubber joining the supporting sleeves and with two recesses corresponding to one another in the spring body. The two parts are so configured and assembled in a unit such that the recesses combine to form liquid-filled, sealed chambers which are in liquid-carrying communication with one another through a passage-like opening. The opening includes, in tandem, a first passage and a second passage of two branch passages which are connected parallel. The two branch passages differ from one another by having cross sections of different magnitude and/or different length and/or different cross-sectional variation over their length. They are preferably disposed in the plane of separation of the rubber sleeve spring. |
