Abstract
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.
