ABSTRACT:
An adjusting device for adjusting the initial injection lift of a double-injection type fuel injection valve comprises a hollow tubular holder which has one end portion, an axially intermediate portion and another end portion provided, respectively, with support elements for supporting a measuring instrument, mounting elements for mounting the holder on a second nozzle spring-accommodating hollow member of the fuel injection valve, and urging elements disposed in the holder for urging a second movable spring-seat of the fuel injection valve against its stationary seat to hold the former in close contact with the latter. The mounting elements allow axial displacement of the holder relative to the hollow member of the fuel injection valve. The above elements of the holder are so constructed as to permit free axial movement of an elongate probe of the measuring instrument therethrough.
