Magnetic valve for hydraulic operated injector has component acting to both centralize armature and close outlet from valve control chamber

摘要

The armature plate (390) of the electromagnet is located centrally on a stud (410) under pressure from a spring (400) to close the valve. A component (150) located in a hole (440) in the valve case (90) serves the dual purpose of centralizing the bolt, and hence the armature, and sealing off the outlet (70) from the valve control chamber
