Abstract:
A solenoid actuated valve for controlling the delivery of a fluid, the solenoid actuated valve comprising:a valve body, the valve body having a valve inlet adapted for communication with a source of fluid and at least one valve outlet;at least one solenoid coil mounted on the valve body; anda sleeve armature slidably mounted on the exterior of the valve body for controlling fluid flow through the valve outlet, the sleeve armature forming at least a portion of an exterior side wall of the valve and being disposed in an overlying relationship with the valve outlet and with at least a portion of the solenoid coil;the solenoid coil being energizable to produce magnetic flux for moving the sleeve armature axially relative to the valve body and the valve outlet between first position and second positions, the sleeve armature forming a portion of a magnetic flux path for magnetic flux produced by the solenoid coil, and the sleeve armature substantially preventing fluid flow through the valve outlet when the sleeve armature is in a first one of said positions, and fluid flow through the valve outlet being permitted when the sleeve armature is moved away from said first position.
