Abstract
In a control equipment for adjusting the moment of fuel injection and/or the amount of fuel supplied by a fuel injection pump in internal combustion engines, at least one mechanical energy accumulator (9, 10) is provided between an adjusting member (2, 3) for the begin of fuel supply and/or for the amount of fuel supplied and an electrical servomotor (4), said energy accumulator comprising two mutually movable spring collars (12, 13) between which is accommodated a pre-stressed compression spring (11) and the maximum distance of which one from the other is limited by abutments (14, 15) of a housing surrounding the spring collars. (FIG. 1).
