ABSTRACT:
An injection timing adjuster for internal combustion engines, by which a mutual rotational position of a driven shaft relative to a drive shaft is variable as a function of operating characteristics. The adjuster includes two pairs of cams serving as adjusting mechanisms, the adjusting cams are connected by bolts to intermediate elements, which in turn each are coupled, by one coupling pin, to two each hydraulically actuatable adjusting pistons disposed parallel to one another on one side of the adjuster. The adjusting pistons are guided in a piston holder, which has two lateral limiting faces, which together with two walls offstanding from the intermediate elements form a sliding guide for the intermediate elements. As a result of an improved sliding guidance, the injection timing adjuster can be used for transmitting higher drive outputs than previously in prior art adjusters.
