Abstract
A tubular outer needle, slidably housed in a body, can communicate nozzle and suck chambers R, Rwith each other and shut them from each other, and defines nozzle and suck chambers R, R. A rod-like inner needle, coaxially slidably housed in the outer needle, has a tip end portion movable into the suck chamber Rat its lowermost position. In the range of small inner lift amount, an annular clearance is formed between an inner peripheral surface of an inner side wall defines the suck chamber Rand an outer peripheral surface of an outer side wall of the needle tip end portion. Outer and inner lift amounts are regulated such that when fuel injection is started, the outer and inner lift amounts simultaneously increase from zero while when fuel injection is terminated, the inner lift amount returns to zero after the outer lift amount returns zero.
