A hydraulically damped rubber cartridge spring has two liquid-filled chambers 1, 3 and 2, 4. The chambers 1, 2, 3, 4 of the chamber pairs are spaced apart from one another in an axial direction, and the chambers 1, 2, 3, 4 of each chamber pair 1, 3 and 2, 4 are connected via a separated damping opening 5, 6 and filled with liquid. Each damping opening 5,6 is dimensioned and adjusted to the sum of the bulging elasticities of the walls of the respective pair of chambers to which it is connected.
