Abstract
A solenoid valve assembly including a movable armature acting through a lost motion unit for moving a valve member to an open position. The lost motion unit stores armature stroke energy during an initial stage of armature stroke, and sums the stored energy with armature stroke energy during a latter stage of armature stroke to open the valve member.
