Abstract

PURPOSE:To enable to prevent occurrence of vapor-lock, by providing a delivery pipe formed therein with a fuel supply passage for supplying fuel to an inlet port of a fuel injection valve and a discharge passage for discharging fuel from an outlet port of the fuel injection valve. CONSTITUTION:Fuel, pressure of which is controlled to a relatively low level by a pressure regulating valve 4, is passed through the inside of an injection valve 1 from an inlet port 20 to an outlet port 22 via a chamber 24 and a portion of the fuel is ejected from an orifice when current is supplied to an electromagnetic coil 12. This injection valve 1 tends to receive heat from an engine and therefore to produce fuel vapor on the inside of the same. However, since fuel is circulated from the inlet 20 to outlet 22, fuel vapor thus produced is discharged to a tank by the above fuel flow through the outlet port 22, an outlet port 32a and a discharge passage 32 of a delivery pipe 3, and the pressure regulating valve 4. Thus, the pipe 3 has a fuel supply passage 30 and the fuel discharge passage 32 formed therein, its structure can be simplified and the pipe connecting operation is rendered easy. Thus, it is enabled to prevent occurrence of vapor-lock.
