Beschreibung
Zusammenfassung:	An adjustable-stroke solenoid valve assembly includes supply, control, and exhaust ports, an inner cavity having first and second seats, a solenoid coil, and a plunger assembly. The plunger assembly includes an armature shifted by the coil. The plunger assembly also includes a stem having a first end adjustably engaged with the armature, and a second end adjustably engaged with a poppet. The plunger assembly additionally includes a first surface that gets pressed against the first seat to block fluid flow to the control port when the coil is de-energized and a second surface that gets pressed against the second seat to facilitate fluid flow to the control port when the coil is energized. Adjustment of the stem's first end relative to the armature and of the poppet on the stem's second end establish a predetermined stroke for the plunger assembly and a predetermined fluid flow rate to the control port.
