ABSTRACT:
This invention relates to the engine technical field, more particularly, an integrated fuel feed apparatus. The integrated fuel feed apparatus including a driving member20, a plunger pump30driven by said driving member, a fuel injector90, a fuel intake member13and a fuel return member14, with a return passage15always communicating the fuel intake member13with the fuel return member14, with some of the fuel in the return passage15being ejected via the fuel injector90under the action of the plunger pump30, featuring that the driving member consists of a solenoid25, a sleeve27and a motion part10which can reciprocate in the sleeve27driven by the magnetic force of the solenoid25, the aforesaid motion part10generating a flow difference while reciprocating in the aforesaid return passage15, thus achieving the fuel flow from the fuel intake member13to the fuel return member14. The integrated fuel feed apparatus specified in the present invention can actively restrain the generation of fuel vapor and further actively discharge the fuel vapor generated therein.
