ABSTRACT:
A solenoid valve has a two piece housing which is made from a hollow cylindrical body and a powdered metal cover. The body is projection welded to the cover. The cover has an induction hardened valve seat and a pair of mounting holes to secure the valve in place. A coil assembly is disposed within the hollow cylindrical body and a two piece armature is disposed within an axial bore of the coil assembly. The upper armature is threadably engaged with an end cover for adjustment and a coil spring is located between the upper and lower armatures to bias the lower armature towards the cover. A ball is located between the lower armature and the cover and the coil spring engages the ball with the valve sleeve. When the coil is de-energized, the valve is closed by virtue of the ball being urged against the valve seat by the coil spring. When the coil is energized the lower armature and ball are magnetically attracted to the upper armature permitting flow through the cover, through the body and out a plurality of holes in the body.
