"textContent": "The present invention provides a fuel injector including a housing, an armature (46), an armature bias spring (32), a needle (68), and a seat (64). The armature (46) has an armature passage (54) including a first portion (90) and a second portion (92). A first cross-sectional area of the first portion (90) is greater than a second cross-sectional area of the second portion (92). The armature bias spring (32) is disposed within the first portion of the armature passage. The needle (68) is disposed within the second portion of the armature passage. A flow restrictor (94) is disposed between the first portion (90) and the second portion (92) of the armature passage of the armature. The flow restrictor (94) includes an orifice (96) having a third cross-sectional area that is less than the first cross-sectional area. The present invention also provides a method of generating flow from a valve assembly without after-flow through the valve assembly when the valve assembly is commanded to terminate a flow cycle.",
