とする列型燃料噴射ポンプ。[Claims for Utility Model Registration] The interior of the injection pump body is divided into a plunger chamber and a governor chamber. The plunger chamber houses a plunger for pressurizing fuel, and the governor chamber houses a control chamber. A governor for driving the rack and controlling the fuel injection amount is housed, and a camshaft extends between the plunger chamber and the governor chamber, and the plunger and the governor can be driven by the camshaft. In the in-line fuel injection system, the injection pump body is provided with an oil supply hole for supplying oil to the plunger chamber and an oil discharge hole for discharging oil from the plunger chamber. In the pump, a pump mechanism driven by rotation of the camshaft is attached to the camshaft in the governor chamber, and the pump mechanism and the inside of the plunger chamber are bored in the camshaft. The row type fuel is connected to the plunger chamber by an oil passage, and the oil in the governor chamber can be discharged to the plunger chamber via the oil passage by the pump mechanism. injection pump.
