ABSTRACT:
An injector includes a boosting mechanism and a nozzle. The boosting mechanism boosts fuel, and the nozzle injects and supplies the fuel boosted by the boosting mechanism. The boosting mechanism includes a tubular piston and a column piston. The tubular piston has a bore, which extends through the tubular piston in a direction of a longitudinal axis of the tubular piston. The column piston is loosely received by the tubular piston and has an end portion, which projects from the tubular piston, and which is engaged with the tubular piston. The tubular piston is slidably received by a first cylinder. The end portion of the column piston is slidably received by a second cylinder, which is provided generally coaxially to the first cylinder, and which has a diameter different from that of the first cylinder.
