Abstract: An air management system including at least one air spring and a compressor. The compressor defines a compartment having an inlet and an outlet. A reservoir is fluidly connected to the air spring and the compressor. A piston is moveable in the compartment and is reciprocally moveable in a compression stroke and an extension stroke in response to actuation of the motor in order to build-up air pressure at the outlet. The piston defines at least one passage extending between the extension chamber and the compression chamber, and at least one check valve positioned in the at least one passage such that air pressure in the compression chamber biases the piston toward the extension chamber to reduce a torque load on the motor during movement of the piston.
