Claim:
1. An armature assembly for a solenoid valve, the armature assembly comprising: a moveably supported armature bolt, the armature bolt being movable between a first position and a second position; a valve member coupled to the armature bolt, the valve member being configured to close with the armature bolt at the second position; an armature body having a uniform cylindrical outer surface that is adapted to slidably engage a channel of a solenoid, the armature body forming an end bore that slidably engages the armature bolt directly; and a guide fixedly engaged with the armature bolt and disposed entirely within a central bore formed in the armature body, the central bore and end bore being aligned along a centerline of the armature body, the guide forming a shoulder extending radially from the guide and disposed at a gap from a limit surface of the armature body within the central bore; and a resilient member disposed within the central bore and extending along the guide between the shoulder and the limit surface of the armature body, the resilient member being in a compressed state to retain the valve member in the closed position by providing a biasing force when the armature bolt is disposed at the second position.
