  "textContent": "A control piston (34) guided in longitudinal movement in a valve body (31) comprises a pressure piston section (35) guided in a bush (33) and a control piston section (36) with a sliding seal having a control edge (45). The control piston section is guided in a control cylinder (41) contained in the pressure chamber (40) of the valve body and separated from the bush. The bush is contained in the pressure chamber of the valve body and partially acted on from the outside with a system pressure. The sealing seat (46) of the control piston acted on by the first pressure surface (38) of the pressure piston section disconnects a valve chamber (47) from a low pressure/return system when a fuel injection valve (10) is in open position. The control edge of the control piston section disconnects the pressure chamber from the valve chamber and simultaneously produces a connection between valve chamber and the low pressure/return system via the sealing seat when the fuel injection valve is in closed position, thereby initiating an actuation of the fuel injection valve. The fuel injection valve is connected to a high pressure source, and a control valve (30) includes the control piston.",
