Abstract
An injection instant adjuster for internal combustion engines is proposed, by means of which the mutual rotary position of an off-drive element relative to a driving element is variable at least in accordance with rpm. The injection instant adjuster includes at least two adjusting cams acting as the adjusting mechanism, which during their rotary movements, effected by control elements, control a 'late' adjustment (.alpha.) of the instant of injection during a first partial rotation (.gamma.) which precedes the 'early' adjustment (.beta.) controlled during the further partial rotation (.delta.). This is possible by means of a suitable selection of the outset position of an adjusting bolt. A detent in the adjusting curve, during which no adjustment takes place within a predetermined rpm range, is controllable at the transition between 'late' and 'early' adjustment by means of the spring sets comprising at least two adjuster springs, whenever the second adjuster spring is installed in the adjuster with initial stress, with the interposition of a spring plate and acting counter to the adjusting force of the control element.
