Abstract

The regulating member according to the present invention is arranged in a pressure line in a fuel injector with a pressure intensifier and has an actuator, a valve chamber and a spring-loaded valve piston arranged moveably in the valve chamber. The valve piston, in its position of rest, makes a flow connection through the valve chamber between a pressure supply and a control space of the pressure intensifier and, in its switching position, the valve piston makes a flow connection through the valve chamber in which the control space in the pressure intensifier is relieved of pressure.
