Abstract
A device presenting a high-pressure pump, and a low-pressure pump connected pstream from the first. To prevent damage in the event of a fault on the device, the connection between the low- and high-pressure pumps is provided with a cutoff valve which is closed in the event of a fault on the low-pressure pump to prevent the intake of solid particles by the high-pressure pump. Also, in the event of a fault on one of the injectors, detected on the basis of the operating conditions of the engine, the low-pressure pump is disconnected to prevent seriously damaging the engine.
