PURPOSE: To easily and simple adapt an entire load injection amount in relation to a rotation frequency by using a ring slider to make an effective pressurized delivery stroke of a plunger be geometrically adjustable with respect to a fuel column under a uniform delivery pressure. CONSTITUTION: A control slider device 18 formed as a control piston slides in a cylinder 2 having a bore 22 and a control edge. Plunger 4 extends from the guide bore 22 at a drive side and projects into an inner chamber 38 filled with fuel. A ring slider 44 regulated by a fuel injection amount regulator 47 is disposed around the circumferential surface of the plunger 4. Further, the ring slider 44 controls an outlet 45 of a longitudinal passageway 41 in the inner chamber 38 with a control edge 43, and controls a control port 62. Consequently, the effective point of time of opening control of an working chamber 25 of a pump carried out via a control edge 43 provided to the control piston 18 is changed in relation to rotation frequency, thus the entire load injection amount can be easily and simply adapted in relation to the rotational frequency. |
