METHOD OF ASSEMBLING FUEL INJECTOR PUMP COMPONENTS |
摘要 |
Methods of swaging fuel injector pump components are provided. A method of securing an armature plate to a control valve of a solenoid-actuated fuel injector pump comprises: (1) providing a control valve stem extending from the control valve, the stem having a body with a body width, a head with a head width narrower than the body width, and a neck with a neck width narrower than the head width, the neck forming an annular groove between the head and body; (2) providing a central aperture formed in the armature plate having an aperture width between the head and body widths; and (3) forcing the stem into the central aperture in a manner to cause a portion of the armature plate to deform into the groove to secure the armature plate to the stem. Also provided is a method of plugging a fuel flow passage in a fuel injector pump body, comprising: (1) providing a plug; (2) inserting the plug at least partially into the passage; and (3) swaging the plug into the passage in a manner to deform a portion of the pump body around the plug to secure the plug in the passage. |
