Abstract
A fluid delivery system for an engine is disclosed. The fluid delivery system comprises a pump, a valve module, a motor, and a displacement control module. The pump is operatively coupled with an engine and is adapted to provide a flow of a fluid. The valve module is provided in fluidic communication with the pump to control the flow of the fluid. The motor is provided in fluidic communication with the valve module to receive the flow of the fluid and generate mechanical power. The displacement control module is provided in fluidic communication with the pump and the valve module and is provided downstream of the pump and upstream of the valve module. The displacement control module controls a displacement of the pump for maintaining a constant flow rate of the fluid from the pump based, at least in part, on an engine speed regardless of compressor load.
