料噴射ポンプ。[Claims for Utility Model Registration] (1) A plunger having suction, discharge and cut-off passages and rotated and reciprocated by a cam disk, a control sleeve and a timer, and which is used to bring the engine into operation. In a type equipped with a control system that electrically controls the mechanism so as to obtain a predetermined fuel injection amount and injection timing, the start of injection is controlled by a solenoid valve provided in a head plug in the axial direction of the plunger, An electronically controlled distribution type fuel injection pump characterized in that the end of injection is controlled by an electromagnetically driven control sleeve. (2) The poppet valve of the solenoid valve consists of two parts: a threaded block and the valve body.The gap with the fixed core can be adjusted by setting the length of the block, and the valve lift can be adjusted by using the shim between the block and the valve body. An electronically controlled distribution type fuel injection pump according to claim 1, which has been registered as a utility model.
