Abstract: 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).
