Abstract:
1. A module solenoid valve for a direct injection, high pressure pump of an automobile fuel delivery system, the solenoid valve comprising: a valve body defining an inlet opening and an outlet opening in communication with the inlet opening, the valve body including a seating surface at a distal end thereof, a valve member at least partially disposed in the valve body, the valve member having a sealing surface associated with the seating surface, a movable armature coupled with the valve member such that movement of the armature moves the valve member between a closed position with the sealing surface engaging the seating surface to prevent fuel from passing through the outlet opening, and an open position with at least a portion of the valve member moving outwardly from the distal end of valve body with the sealing surface being disengaged from the seating surface to permit fuel to pass through the outlet opening, a stator associated with the armature, a first spring engaged between the armature and stator and constructed and arranged to bias the armature and thus the valve member to the closed position, a cover coupled to the stator, the cover being separate from the stator, a second spring engaged between the cover and the armature, the second spring being constructed and arranged to provide a biasing force on the armature, with the cover being deformed to adjust the biasing force, and an electromagnetic coil associated with the stator and armature for causing movement of the armature towards the stator.
