An air suspension for a vehicle includes at least one air spring per wheel at at least one vehicle axle, one pump, at least one accumulator, and one circuit arrangement for connecting these units, the pressure side of the pump being connected to the accumulator or the air springs. To form a closed compressed-air system, the intake side of the pump is connected via at least one valve to the accumulator or the air springs, and at least the air-guiding interior pump chambers between the intake side and the pressure side of the pump have a pressure-tight design. The air suspension system requires comparably low energy consumption and small unit volume at a high level of efficiency.
