摘要： A non-return valve assembly for a high-pressure fuel injection system is disclosed. The valve comprises a valve chamber defined in part by a first body and in part by a second body and defining a valve chamber wall, an inlet passage formed in the first body and opening into the valve chamber at a valve seat defined by the first body, an outlet passage, and a valve ball received within the valve chamber and engageable with the valve seat so as to interrupt fluid flow from the outlet passage to the inlet passage through the valve chamber. The valve chamber wall comprises a plurality of guide portions to guide the valve ball in substantially linear movement within the valve chamber.

摘要： The present invention relates to a fuel injector for use in delivering fuel to an internal combustion engine. The fuel injector includes a nozzle having a valve needle which is movable with respect to a valve needle seat. The valve needle travels through a range of movement between a closed position and an open position to control fuel delivery through at least one nozzle outlet. The valve needle cooperates with a needle sleeve or a control member which is located in a piston guide. The valve needle is movable relative to the needle sleeve or the control member. The needle sleeve or the control member is movable relative to the piston guide. The invention also relates to a method of operating a fuel injector; and a fuel injector control unit.

摘要： The present invention relates to a 3-way valve assembly (102; 202; 302) for a fuel injector (101; 201; 301). The valve assembly (102; 202; 302) includes a valve body (103; 203; 303), a movable valve member (104; 204; 304), and an armature (113; 213; 313) for actuating the valve member (104; 204; 304). The armature (113; 213; 313) is disposed in an armature cavity (115; 215; 315). The valve member (104; 204; 304) is configured to control an operating pressure in a control chamber (105). The valve body (103; 203; 303) includes a bore (117; 217; 317) in which the valve member (104; 204) is disposed. A leak vent (121; 221) is provided for venting fuel leaking through the bore (117; 217) past said valve member (104; 204). In an alternate embodiment, a partitioning member (333) is disposed in the armature cavity (315).
