Patent ID: 7871058

Claim:
A fluid dispensing valve assembly, comprising: a dispensing nozzle for dispensing a fluid; a valve seat member having a valve seat defined thereon; a valve assembly, movably disposed with respect to said valve seat between first CLOSED and second OPENED positions, for controlling the flow of the fluid toward said dispensing nozzle; said valve assembly comprising a valve stem and a valve member disposed upon a first end portion of said valve stem for operatively cooperating with said valve seat of said valve seat member; a first armature fixedly disposed upon a first portion of said valve stem so as to be disposed remote from said valve member disposed upon said first end portion of said valve stem; a second armature fixedly disposed upon a second portion of said valve stem so as to also be disposed remote from said valve member disposed upon said first end portion of said valve stem and to also be spaced from said first armature fixedly disposed upon said valve stem; a first electromagnetic solenoid assembly operatively connected to said first armature and said valve assembly for moving said first armature, said valve stem, and said valve member in a first direction with respect to said valve seat whereby said valve member will be disposed upon said valve seat and at said CLOSED position, when said first electromagnetic solenoid assembly is energized, so as to prevent the dispensing of the fluid from said dispensing nozzle; a second electromagnetic solenoid assembly operatively connected to said second armature and said valve assembly for moving said second armature, said valve stem, and said valve member in a second opposite direction with respect to said valve seat, whereby said valve member will be unseated from said valve seat and disposed at said OPENED position, when said second electromagnetic solenoid assembly is energized, so as to permit the dispensing of the fluid from said dispensing nozzle; a housing within which said first and second electromagnetic solenoid assemblies are mounted; and a stop member, adjustably mounted within said housing so as to engage said valve stem, when said valve stem is moved from said first CLOSED position to said second OPENED position, such that the stroke movement of said valve stem, and said valve member mounted thereon, between said first CLOSED position and said second OPENED position, is defined.
