Abstract

PURPOSE: To provide possibility of precise adjustment of the fuel injection timing by permitting a slider supporting an eccentric cam and movable in the radial direction to work in cooperation with an oil-hydraulic piston which is in contact with the s lider and movable in the axial direction.
CONSTITUTION: A hub 16, which is incorporated in a rotary flange 10 which rotates in synchronization with the engine and is coupled with a cam shaft 17, is provided with a large pair 33a and small pair 33b of eccentric cams, and a pair of sliders 19 are provided with an eccentric pin 20 supporting the large eccentric cam 33a, where the inclined surface 19a is always in contact with the mating inclined surface of ring-shaped piston 21 sliding axially guided by the boss part 16a of hub 16 and the internal surface 13b of sleeve 13. The small eccentric cam 33b is coupled with the rotary flange 10 by an eccentric pin 38. Consequently, motion of the piston 21 in the axial direction by hydraulic pressure will yield a phase difference between the rotary flange 10 and hub 16, and thus the injection timing can be adjusted.
