Abstract
An electric solenoid valve and method therefor including an armature reciprocatably disposed in an axial bore of a housing member having a fluid inlet and a fluid outlet coupled to the axial bore at a first end thereof. The armature includes a valve member disposed at a first end portion thereof, and a magnetically attractable second end portion defining a second end thereof disposed toward a fixed core portion of the solenoid. The armature also includes an interior fluid passage with a fluid inlet disposed between the fluid inlet of the housing member and the second end of the armature to couple the interior fluid passage with the fluid inlet of the housing member. A fluid outlet is disposed proximate the valve member of the armature and is coupleable to the fluid outlet of the housing member when the valve member is unseated from a valve seat disposed along the axial bore proximate the fluid outlet of the housing member, whereby the electric solenoid valve has reduced fluid stagnation, improved actuation responsiveness, and is integrateable with fluid dispensing systems.
