A control chamber (184) for fuel is provided, preferably at least in part, between the first valve needle and the second valve needle, wherein movement of the first valve needle is responsive to fuel pressure in the control chamber, and wherein movement of the second valve needle is mechanically coupled to an armature of the first actuator arrangement (159), such that when the second valve needle lifts away from the second seating region, a fuel flow path is established between the control chamber and the second set of nozzle outlets. The fuel injector further includes a second actuator arrangement (200) that is operable to control fuel flow into the control chamber thereby regulating fuel pressure within the control chamber and, thus, movement of the first valve needle.

    Abstract: An inlet valve assembly (14) for a high-pressure fuel pump is disclosed. The inlet valve assembly comprises an inlet valve member (28) moveable between open and closed positions to control the fuel flow from a source (24) of low-pressure fuel to a pumping chamber (16) of the fuel pump, and an electromagnetic actuator (50) comprising a core member (52), a solenoid coil (54), and an armature (58) moveable towards the core member (52) in response to energisation of the coil (54). In a first phase of operation, the armature (58) is decoupled from the valve member (28) to allow movement of the armature (58) towards the core member (52) without movement of the valve member (28) and, in a second phase of operation, the armature (58) is coupled to the valve member (28) to carry the valve member (28) towards its closed position. Because the armature (58) is initially decoupled from the valve member (28), variations in concentricity and part dimensions due to manufacturing tolerances can be accommodated without affecting operation of the valve assembly.
