摘要

A control valve has a valve piston (6) that moves in a casing (1) and is surrounded by an outer valve space (19) into which an inlet (20) on the casing side flows from a common rail. An actuator (3) operates the valve piston. A jet inlet (18) to an injection jet can be released or locked off. Two interconnected 2/2-way valves (37,38) fit on the valve piston.
