A pneumatic suspension system for a vehicle includes a compressed air accumulator, a compressed air transport device, at least one pneumatic bellows and an electrically controllable reversing valve used to connect the compressed air accumulator to a suction connection of the compressed air transport device, in order to increase the amount of air in the pneumatic bellows in a first switching position, and to connect an outlet connection of the compressed air transport device to the pneumatic bellows, also used to connect the pneumatic bellows to the suction connection of the compressed air transport device and the outlet connection of the compressed air transport device to the pressure accumulator in a second switching position in order to reduce the amount of air in the pneumatic bellows. The reversing valve can be pre-controlled with the compressed air of the pneumatic suspension system.
