A self-pumping hydropneumatic suspension strut includes a high pressure area and a low pressure area, wherein pressurized medium is exchanged between the high pressure area and the low pressure area via a passive pump device. At least two separate channel systems with connection orifices which determine level position and are controlled depending on the position of a piston rod are provided between the high pressure area and the low pressure area. One of the channel systems can be blocked by a valve device, and wherein the suspension strut has a displacing device with a spring seat for a supporting spring. The displacing device is operated via the working movement of the piston rod.
