PROBLEM TO BE SOLVED: To realize a housing case for overflow valve and its using method which simplifies a packing work and prevents a shortage of part. SOLUTION: A housing case 10 for overflow valve is composed of a small diameter part 12, a large diameter part 13, and a blank cap 14. At first, two washers 9 are superposed on each other when an overflow valve 5 is assembled to a valve main body 6, and the two washers 9 are moved to the level one washer is abutted to a nut 7. Then, the valve main body 6 of the overflow valve 5 is inserted in the housing hole 11 of the housing case 10. Finally, the blank cap 14 of the housing case 10 housing the overflow valve 5 is screwed and fastened in the fuel passage 2a of the nipple 2 of a fuel injection pump 1. Since the fuel injection pump 1 and the overflow valve 5 can be packed integrally by using the housing case 10, the packing work can be carried out simply. |
