  • Patent number: 10202968
    Abstract: Provided herein are systems that enable proportional air flow delivery control for an air compressor. One system includes a pneumatic air compression system having a flow control member and being adapted to receive inlet air and to compress the inlet air to produce compressed air. The system also includes a pneumatic flow control system including a proportional control valve having a proportionally variable activation state. Varying the activation state of the proportional control valve regulates a pressure acting on the flow control member to regulate the flow of the compressed air produced by the pneumatic air compression system in a variable manner, and further regulates a power demand placed on the engine by the pneumatic air compression system in a variable manner.
