Abstract
An injection timing device is proposed for internal combustion engines, by means of which the mutual rotary position of the output shaft with respect to the input shaft can be varied at least in dependence on the speed. The timing device comprises at least one pair of eccentrics which serve as the adjusting gear system and comprises an adjusting eccentric and a compensating eccentric, this pair of eccentrics being supported in a bearing member connected to one of the shafts, the adjusting eccentric of this pair also being coupled by means of a transmission member with a hydraulically operable servo piston. By a positional change of the servo piston effected by the hydraulic medium, the adjusting eccentric can be rotated to change the instant of injection.
