ABSTRACT:
An electromagnetic dispenser (10) for dispensing viscous heated fluids, such as hot melt adhesives. A fixed pole (50) extends from a fluid chamber (20). The coil (46) is located about a portion of the fixed pole (50) and spaced from the fluid chamber to isolate the coil from the fluid flow path of the adhesive. The coil is insulated from the heat which is conducted from the adhesive as well as provided with a heat sink (88) for dissipating heat. A plunger (32) is mounted within the fluid chamber for reciprocal movement therein to open and close dispensing orifice in response to the field generated by the coil.
