- an injector for fuel injection is provided, wherein each injector is connected via a hydraulic line to the high-pressure accumulator.
- an electric control device is provided for controlling the fuel injection by the injectors.
- the lines to the injectors and the injectors are part of the high pressure range. to
- a pressure control valve is provided, which is controlled by the control device.
- the pressure control valve By the pressure control valve, a connection of the high-pressure region is controlled with a low-pressure region. If that
- Pressure control valve is controlled by the control device, so this releases the connection of the high pressure area with the low pressure area, so that fuel from the High pressure range can flow into the low pressure range.
- novel fuel injectors complete tightness of the high pressure area is achieved.
- the fuel in the high-pressure region is heated.
- it may come to a degassing of the fuel because of the complete tightness of the high pressure area.
- the restart of the internal combustion engine is difficult because first the gas must be displaced in the high pressure area.
- the fuel injection device with the features of claim 1 has the advantage that when the internal combustion engine, if the pressure control valve is not controlled by the control device, the high pressure region is connected to the low pressure region, so that a degassing of the fuel in the high pressure region is avoided.
- FIG. 1 shows a
- FIG. 1 Fuel injection device for an internal combustion engine in a simplified representation according to a first embodiment, Figure 2 shows an injector of
- Figure 3 is a pressure control valve of

- the actuator 16 is driven by an electronic control device 18.
- the actuator 16 is arranged in a fuel-filled space 20 in a housing 22 of the injector 12.
- the actuator 16 may, for example, act on a piston 17 through which a Control chamber 19 is limited, wherein the injection valve member 15 is acted upon by the pressure prevailing in the control chamber 19 in the closing direction.
- the piston 17 is held by a prestressed spring 21 in contact with the actuator 16.
- the injection valve member 15 is also acted upon by a prestressed spring 23 in the closing direction.
- an electrical voltage is applied to the actuator 16 by the control device 18, it expands and pushes the piston 17 into the control chamber 19, in which there is thus a high pressure, through which the
- Injection valve member 15 is held in its closed position, so that no fuel injection takes place. If no voltage is applied to the actuator 16 by the control device 18, this reduces its expansion, so that the piston 17 is moved out of the control chamber 19 by the spring 21, whereby the pressure in the control chamber 19 decreases. The injection valve member 15 is then by acting on this in the opening direction high pressure against the prevailing in the control chamber 19 low pressure and against the force of the spring 23 in his
- Opening position moves so that fuel is injected.

- the return spring 52 the valve member 46 is acted upon in its opening direction, in which this is lifted with its closing body 47 from the valve seat 48 and thus the connection 44 of the high-pressure region is opened with the low-pressure region.
- the valve member 46 When the actuator 50 is actuated by the control device 18, the valve member 46 is held against the return spring 52 and against the pressure prevailing in the high-pressure region in its closed position, in which it abuts the valve seat 48 with its closing body 47, so that the high-pressure region is separated from the low-pressure region is.
- the pressure valve member 46 By prevailing in the high pressure region, for example in the memory 26, the pressure valve member 46 is acted upon in its opening direction in which this is lifted from the valve seat 48 and thus the connection 44 of the high pressure region is opened with the low pressure region. If the actuator 50 is not activated, then the valve member 46 is opened against the force of the closing spring 52 by the pressure prevailing in the high-pressure region and the connection 44 is opened to the low-pressure region.
- the control device 18 receives a signal for the actual pressure in the high-pressure region.
- Pressure control valve 42 is no longer actuated by the control device 18, so that this is in its open switching position and the high-pressure region is connected to the low-pressure region. Upon cooling of the fuel present in the high-pressure region, the volume in the high-pressure region can thus be removed from the fuel Low pressure area are filled so that no gas can form in the high pressure area.
- the pressure regulating valve 42 is actuated by the control device 18, so that this is in its closed position. In the fuel delivery through the high-pressure pump 10, high pressure quickly builds up again in the high-pressure area, so that the
- Internal combustion engine can be operated after a short start time.
