Fuel injection device for an internal combustion engine |
摘要 |
A fuel injection apparatus has a high-pressure pump and a fuel-supply pump that delivers fuel from a fuel tank to the high-pressure pump. The high-pressure pump has a housing with an internal chamber that contains a drive unit for at least one pump element having a pump piston driven by the drive unit and delimiting a pump working chamber into which fuel is supplied via an inlet during an intake stroke and from which fuel is displaced via an outlet into the reservoir during a delivery stroke of the pump piston. The fuel-supply pump delivers fuel into the internal chamber via a connection that contains a check valve which opens toward the internal chamber of the housing and the inlet of the pump working chamber is connected to the internal chamber.
