摘要: 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.

摘要: 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.

摘要: An inlet valve assembly for a high-pressure fuel pump is disclosed. The inlet valve assembly comprises an inlet valve member moveable between open and closed positions to control the fuel flow from a source of low-pressure fuel to a pumping chamber of the fuel pump, a first biasing spring arranged to apply a first force to the valve member in an opening direction, a second biasing spring arranged to apply a second force to the valve member in a closing direction, and an actuator arrangement operable to remove the first force from the valve member, thereby to allow the valve member to move into its closed position.
