<p>PROBLEM TO BE SOLVED: To provide a fuel injection pump including a delivery valve capable of being integrated as a unit or decomposed into component elements as needed.SOLUTION: In a fuel injection pump 100, a delivery valve 10 includes a cylindrical delivery holder 11, an annular sleeve 12 fitted to an inner periphery of the delivery holder 11, and a check valve 13 sliding in the annular sleeve 12. A groove 11a is formed on the inner periphery of the delivery holder 11 in the circumferential direction, a C-shaped retaining ring R1 is engaged with the groove 11a, and an inner diameter of the retaining ring R1 is smaller than an outer diameter of the annular sleeve 12. When the annular sleeve 12 is fitted to the inner periphery of the delivery holder 11, the annular sleeve 12 is inserted to the retaining ring R1, and the annular sleeve 12 is supported by the retaining ring R1 of which a diameter is expanded.</p> |
