Abstract
A fuel delivery system having a fuel reservoir connected to a suction side of a pump, a fuel delivery line connected to an output side of the pump, a number of fuel injectors connected to the delivery line, and a return line from the injectors to the suction side of the pump. The pump has a housing, a pumping chamber within the housing, a driver rotor and a driven rotor within the pumping chamber, and an input shaft t the housing. The input shaft is arranged such that rotation of the input shaft effects rotation of the driver rotor. The driver rotor is caused to rotate by the input shaft via a magnetic coupling. The magnetic coupling is arranged to slip when a predetermined value of torque is applied across the coupling such that a maximum pressure value of about 12 bar is attained at the output side of the pump.
