ABSTRACT:
The invention relates to a solenoid-valve-controlled injection device, comprising pump and nozzle, for an air-compressing internal combustion engine having an electromagnetically actuatable control valve. The valve stem of the control valve co-operates with a control slide which is designed as an inertia piston and, via its control bore and a bore arrangement in the valve stem, establishes a connection between a fuel injection line leading to the nozzle and a return line in order to divide the injection into a temporally staggered pre- and main injection.
