Beschreibung
Zusammenfassung:	A high-pressure fuel pump for an internal combustion engine is described. The high-pressure fuel pump includes an improved configuration that beneficially simplifies certain features of the high-pressure fuel pump. More specifically, the disclosure provides for an inlet check valve positioned along an inlet fuel circuit and an outlet fuel circuit of the high-pressure pump that provides a path for a low-pressure inlet fuel flow to and a path for a high-pressure output fuel flow from a pumping chamber of the fuel pump. Because of the configuration of the inlet check valve and the outlet check valve, the complexity of high-pressure fuel pump is beneficially reduced, decreasing the cost of components and assembly and improving the life and reliability of high-pressure fuel pump.
