圧タイマー付き燃料噴射ポンプ。Fuel can be pumped by reciprocating the plunger 12 within the barrel 10, while an annular valve 13 is fitted on the outside of the plunger 12 and the annular valve 13 and the plunger 12 are relatively rotated to transfer the fuel. The fuel injection timing is controlled by controlling the injection amount and displacing the annular valve 13 relative to the plunger 12 in the axial direction by a piston 55 that is displaced according to the feed pressure of the feed pump 6 that rotates synchronously with the engine. A fuel injection pump with a hydraulic timer capable of controlling the piston 5.
5 and the annular valve 13, an appropriate transmission mechanism Y is interposed between the piston 55 and the annular valve 13 to non-linearly transmit the displacement of the piston 55 to the annular valve 13 via the cam 48. Fuel injection pump with timer.
