Abstract:
An electrically operated fluid dispenser for dispensing a viscous fluid onto a substrate comprising:a first body comprisinga fluid passage havinga first end intersecting a first side of said first body, said first end of said fluid passage adapted to receive the viscous fluid directly from a source of pressurized fluid, anda second end intersecting a second side of said first body, said second end of said fluid passage not receiving the viscous fluid directly from the source of pressurized fluid, andan outlet in fluid communication with said fluid passage;a first armature disposed in said first body and movable between an opened position allowing a fluid flow from said outlet and a closed position preventing the fluid flow from said outlet;a first coil mounted adjacent said first armature and selectively generates an electromagnetic field capable of moving said first armature between the opened and closed positions; anda first heater for maintaining said first coil at a substantially constant temperature.
