Abstract

A control valve and a fuel injection valve provided with same should be produced, in which it is possible to switch from a first operating state to a second operating state inexpensively and with short switching times, without requiring a hydraulic control line. To this end, a control valve is provided, which has a valve housing, a pressure chamber filled with electrorheological fluid, a displacing element that can slide in the valve housing and protrudes into the pressure chamber, and two electrodes that can apply an electrical field to the electrorheological fluid.
