Abstract
An apparatus for dispensing viscous fluids, such as adhesives, sealants, caulks is actuated by an electromagnetic coil assembly (42,136) in conjunction with a magnet (38,126) mounted to a plunger (26,118). Energizing the coil assembly produces an electromagnetic field which cooperates with the magnetic field to cause the plunger to open. Closing results from reversing the electromagnetic field.
