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.

Abstract: An actuator assembly of a digital inlet valve for a fuel pump adapted to cooperate with an inlet valve member includes an actuator body in which is fixed a coil, a cover closing the body and, a magnetic core arranged in a core guiding bore provided in the actuator body. The magnetic core is slidable along a main axis in order, in use, to close an air gap under the influences of a first compression spring, and of a magnetic field, the core cooperating with the valve member.
