More Information
Summary:In the present invention, a cylinder chamber (20) is provided in a main injector body (10) having a nozzle (11) that injects fuel; in the cylinder chamber (20), a command piston (30) for driving a needle (60) that opens/closes the nozzle (11) is reciprocably housed; and at the cylinder chamber (20), a cleaning liquid supply pathway (70) for supplying cleaning liquid and a cleaning liquid discharge pathway (80) for discharging cleaning liquid are connected. As a result, since adhesive accretions in the cylinder chamber (20) of the main injector body (10) are discharged out of the cylinder chamber (20) together with the cleaning liquid, it is possible to prevent a negative effect resulting from the adhesive accretions without using an additive or the like.
