Abstract:

Propulsion systems for vehicles are provided. The propulsion system includes an engine and a module. The module includes a fuel pump, a check valve, and a relief valve. The fuel pump is configured to supply fuel flow having a pressure. The check valve is configured to receive the fuel flow from the fuel pump, and to allow passage of the fuel flow to the engine. The relief valve is coupled to the fuel pump and configured to release a portion of the pressure of the fuel flow. The relief valve is disposed upstream of the check valve.
