Electro-magnetic damper with air spring

A damper system for a vehicle, comprising:

• a pressurized gas damper including a first working chamber and a second working chamber, each filed with a pressurized gas, that are fluidly connected by a flow control orifice, the pressurized gas damper including a damper tube that houses the second working chamber and extends between first and second damper tube ends;
• an electromagnetic actuator including a magnetic rotor fixed to and extending annularly about the damper tube and a stator assembly extending annularly about a stator cavity that slidingly receives at least a portion of the magnetic rotor and the first damper tube end such that the stator assembly is translatable relative to the damper tube and the magnetic rotor in a compression direction and an extension direction, the first working chamber positioned within the stator cavity;
• and
• a pressurized gas spring including a bellows element extending between a first bellows end that is sealingly engaged with the stator assembly and a second bellows end that is sealingly engaged with the damper tube to define a bellows chamber that extends annularly about at least a portion of the damper tube,
• wherein the damper system is devoid of a piston and piston rod that is longitudinally translatable relative to the damper tube, where the flow control orifice generates a pressure differential between the first working chamber and the second working chamber when the stator assembly moves relative to the damper tube.
