Apparatus for dispensing heated fluid materials

An apparatus for dispensing heated fluid materials comprising:

• an inlet means adapted for coupling to a manifold or a service block for receiving heated fluid materials;
• a means for generating an electromagnetic field, said means being capable of being removed and replaced without disconnecting the inlet means from the manifold or service block when coupled thereto;
• an outlet means, coupled to the inlet means, for dispensing said heated fluid materials therefrom;
• a means movable from a first position to a second position in response to the generated electromagnetic field, wherein the dispensing of said heated fluid material is blocked in said first position and wherein said heated fluid material flows from said outlet means in said second position;
• and
• a heat dissipating means for removing heat from the means for generating the electromagnetic field.

The method of establishing a magnetic gap of an electric dispenser comprising the steps of:

• assembling a fixed pole to a first body having a cavity therein and disposing a plunger and a spring within the cavity to form a first assembly;
• inserting the first assembly into a dispenser body until the plunger is fully seated;
• causing a means to engage both the first body and the dispenser body to prevent further movement therebetween;
• and then
• installing a spacer between a nozzle adapter and the dispenser body, the spacer having the same thickness as that of a desired magnetic air gap between an end of the fixed pole and the plunger.
