An arrangement of a high-pressure valve at the end of a common rail of a fuel injection system, a high-pressure channel of the rail opening out at one extremity of the rail, includes a throttle stopper arranged at the extremity of the rail. An output orifice restricts a section of the high-pressure channel and a valve seat is positioned in the throttle stopper. The output channel is fully formed inside the valve body.

Integrated arrangement of a high-pressure valve and an injection rail

A valve arrangement comprising: a valve outlet for communication with a low pressure drain; a valve housing provided with a bore for receiving fuel from an accumulator volume; and a valve member having a closed position in which it engages a valve seating defined by the bore to prevent fuel flow from the accumulator volume to the valve outlet. The valve arrangement further comprises a first restricted flow means for restricting the flow of fuel between the accumulator volume and the valve outlet during a first stage of valve opening movement; a second restricted flow means effective during a second stage of valve opening movement to provide a greater restriction than during the first stage; and a third restricted flow means effective during a third stage of valve opening movement to provide a variable restriction to fuel flow dependent on the extent of opening movement of the valve member.
