Fuel-feeding devices

Abstract

A fuel-feeding device may preferably include a reservoir cup disposed in a fuel tank that contains liquid fuel therein, a fuel pump capable of feeding the liquid fuel contained in the reservoir cup to an engine, a pressure regulator capable of controlling a fuel pressure of the liquid fuel fed to the engine from the fuel pump, a jet pump arranged and constructed to receive a part of the pressurized liquid fuel pumped from the fuel pump via a fuel jet path, so as to introduce liquid fuel outside the reservoir cup into to the reservoir cup with the aid of flow of the pressurized liquid fuel, and a flow rate control valve disposed in the fuel jet path. The flow rate control valve is arranged and constructed to control a flow rate of the pressurized liquid fuel fed to the jet pump depending upon a pumping rate of the pressurized liquid fuel pumped from the fuel pump.
