Patent ID: 7574297

Claim:
A fuel injection device for an internal combustion engine comprising: a high pressure pump that delivers fuel into a high-pressure region containing at least one injector that injects fuel into a cylinder of the engine, an electric control unit that controls the fuel injection of the at least one injector, and a pressure control valve operable to adjust the pressure prevailing in the high-pressure region, the pressure control valve being connected to control a connection of the high-pressure region to a fuel-filled low-pressure region and being triggered by the control unit to open a connection between the high-pressure region and the low-pressure region, and when it is not being triggered by the control unit, the pressure control valve assumes an open switched position in which the connection between the high-pressure region and the low-pressure region is open, such that when the internal combustion engine is switched off and the control unit is not triggering the pressure control valve, the high-pressure region is connected to the low-pressure region. thus preventing a degassing of the fuel in the high-pressure region.
