Abstract
The invention relates to a device for supplying an internal combustion engine with fuel, having a fuel reservoir and a high-pressure pump, which are connected through a suction line, a metering valve which effects a change of the passage cross-section of the suction line, a rail for receiving high-pressure fuel, and a pressure control valve for controlling the pressure in the rail. The metering valve and the pressure control valve are combined in a common housing and have opposite opening directions. The metering valve and the pressure control valve have closing members which are rigidly connected to each other and are movable on a coincident movement axis.

A device for supplying an internal combustion engine with fuel, including:
- a fuel reservoir and a high-pressure pump, which communicate through an intake line;
- a metering valve, which effects a change in a flow cross section of the intake line;
- a rail for receiving fuel subjected to high pressure;
- and
- a pressure regulating valve for regulating the pressure in the rail, wherein the metering valve and the pressure regulating valve are united in one common housing and have opposite opening directions, and the metering valve and the pressure regulating valve have closing members, which are rigidly connected to one another and are displaceable along a coinciding movement axis.
