<p>The device includes a high-pressure pump (15), a low-pressure pump (10), and an on-off valve (71) between the two pumps (10, 15); the low-pressure pump (10) is activated mechanically by transmission means (75) connected to the shaft of the diesel engine; the on-off valve (71) is so sized as to be activated rapidly at the cranking stage; to dispose of the surplus fuel following activation of the on-off valve (71), the on-off valve (71) opens an additional opening (77) for draining the fuel into an inner chamber (23); and a solenoid valve (79) between the low-pressure pump (10) and the on-off valve (71) is activated automatically to cut off supply to the on-off valve (71) in the event of a fault. <IMAGE></p> |
