摘要： An injection nozzle for an internal combustion engine, the injection nozzle including an outer valve needle which is engageable with an outer valve seating so as to control injection through a first nozzle outlet, an inner valve needle which is movable within the outer valve needle and engageable with an inner valve seating so as to control injection through a second nozzle outlet, and a coupling arrangement for coupling movement of the outer valve needle to the inner valve needle in circumstances in which the outer valve needle is moved away from the outer valve seating beyond a predetermined amount, thereby to permit fuel injection through both the first and second nozzle outlets. The outer valve seating defines first and second seats for the outer valve needle, wherein co-operation between the outer valve needle and the first seat controls fuel flow between a first delivery chamber and the first nozzle outlet and co-operation between the outer valve needle and the second seat controls fuel flow between a second delivery chamber and the first nozzle outlet. The second delivery chamber communicates with the first delivery chamber by way of a supplementary flow path defined, at least partially, within the outer valve needle. The coupling arrangement includes a resilient member carried by the outer valve needle, the resilient member being brought into engagement with the inner valve needle following movement of the outer valve needle beyond the predetermined amount so as to cause the inner valve needle to move together with the outer valve needle.

摘要： An injection nozzle for an internal combustion engine has a valve member moveable within a bore of a nozzle body, and a seating surface defining a seat cone angle the valve member including a first frustoconical valve region, a second frustoconical valve region, and an annular groove defining, in part, a delivery chamber in communication with at least one nozzle outlet. The annular groove is disposed intermediate the first and second valve regions such that a first seating line is defined at the mutual interface between the first valve region and the annular groove and is engageable with the seating surface to control delivery of fuel from a first supply chamber to the deliver chamber, and a second seating line is defined at the mutual interface between the second valve region and the annular groove and is engageable with the seating surface to control delivery from a second supply chamber to the delivery chamber. The second supply chamber is in communication with the first supply chamber by way of a flow path defined within the valve member and as the first and second seating lines are disengaged from the seating surface, fuel is permitted to flow past the first and second seating lines into the at least one nozzle outlet. By virtue of the provision of the first and second valve seats, the flow path and the delivery chamber, the injection nozzle exhibits improved fuel delivery characteristics.

摘要： A fuel injector comprising a nozzle having a nozzle needle which is moveable with respect to a first needle seat to control fuel delivery through a nozzle outlet. The injector includes a nozzle control valve for controlling fuel flow into a control chamber through a first passage to pressurise the control chamber, and for controlling fuel flow out of said control chamber through said first passage to depressurise the control chamber. Movement of the nozzle needle is controlled by fuel pressure within the control chamber, such that pressurising the control chamber causes the nozzle needle to be urged against the first needle seat to close the nozzle outlet, and depressurising the control chamber causes the nozzle needle to lift from the first needle seat to open the nozzle outlet. The nozzle needle defines, at least in part, a restricted passage through which fuel can flow into the control chamber as the control chamber depressurises. The fuel flow into the control chamber through the restricted passage serves to reduce the rate at which the control chamber depressurises, thereby reducing the rate at which the nozzle needle lifts from the first needle seat to open the nozzle outlet.

The injector includes a nozzle control valve for controlling fuel flow into a control chamber through a first passage to pressurise the control chamber, and for controlling fuel flow out of said control chamber through said first passage to depressurise the control chamber.
