POMPA DI COMBUSTIBILE AD AZIONAMENTO ELETTRICO, ATTO AD ESSERE IMPIEGATA IN IMPIANTI DI INIEZIONE PER MOTORI A COMBUSTIONE INTERNA AD ACCENSIONE COMANDATA |
摘要 |
An electrically-operated fuel pump is provided for supplying fuel to the fuel injection system of a spark-ignition I.C. engine. The pump comprises a casing wherein there is located a small electric motor and a rotary pumping assembly. The rotor of the motor is drivingly coupled to the impeller of the pumping assembly. The pump also includes a pressure relief valve for preventing the build up of excessive pressures within the casing, and a non-return valve provided at the pump outlet. The pump casing serves not only as a fuel containment member and a mechanical supporting structure, but also as the magnetic frame of the motor stator. |
