ABSTRACT:
A method and an apparatus for dispensing liquid material to a substrate comprising a housing having a bore and an inlet for supplying liquid material from a material source to the bore. A nozzle communicates with the inlet and includes a discharge opening for dispensing the liquid material. A movable plunger is mounted for reciprocal movement between a closed and an open position. In the open position, liquid material is dispensed from the discharge opening and in the closed position, liquid material is prevented from being dispensed from the discharge opening. An actuator moves the plunger between the closed and the open position. The plunger has at least one slot extending from the outer periphery toward the center of the plunger.
