Abstract

The control is for isolating electromagnetic injection nozzles in electronically controlled injection installations controlled by a common power stage with an intermediary connection of a distributor arrangement and a pre-resistance bridged over by a condenser. The pre-resistance is formed by two series connected part resistances (Rv1, Rv2), between which a power electrode (A) of a thyristor (Th) is connected. The other thyristor power electrode (K) is connected to the second part resistance (Rv2), the electro magnets (M1, Mn) and possibly the distributor (3). The control electrode (G) of the thyristor (Th) is connected to a control connection (2) at the output (A) of which an impulse is released by exceeding the permissible switch-on time (fmax) of the power stage (1).
