Claims

[Scope of utility model registration request]

A rotor is rotatably installed in a cylindrical hydraulic head, and a metering valve is arranged in the hydraulic head to intermittently supply the supplied fuel to the central shaft passage in the rotor, and the fuel in the central shaft passage is transferred to the plunger. It is a distribution type fuel injection pump configured to pump by sliding and distributed to the discharge hole of the hydraulic head from the central shaft passage, and further equipped with a control box to catch fuel leakage from the rotor, and is a manual feed pump. When the feed pressure is activated, the first valve opens in the feed direction only when the feed pressure is activated, and communicates with the metering valve and the central shaft passage, and the pump chamber between the plungers and the inside of the control box are connected to each other when the feed pressure is activated. 1. An air bleed device for a distribution type fuel injection pump, characterized in that a second valve is interposed and communicated with the second valve, which opens only in the feed direction.
