Abstract
A pressure regulator for a power source may include a housing in fluid communication with a pressurized fluid line and a reservoir, and a pressure relief valve having an open position that creates a flow path between the pressurized fluid line and the reservoir, and a closed position. The pressure relief valve may open when an opening force exerted by pressurized fluid entering the housing overcomes a closing force acting on the pressure relief valve, allowing pressurized fluid to flow from the pressurized fluid line to the reservoir. The pressure regulator may also include a governor coupled to the pressure relief valve, wherein the governor is configured to regulate the pressure in the pressurized fluid line by selectively adjusting the closing force exerted on the pressure relief valve based on engine speed.
