ABSTRACT:
A dispenser (10, 32) that provides accurate control of the material dispensed has an upper adjuster (27) which is used to adjust the distance that the dispenser's (10, 32) plunger (23) is withdrawn from the dispenser's (10, 32) material reservoir (17), and a separate lower adjuster (28) to adjust the distance that the plunger (23) is inserted into the cavity (17) to dispense the material. The dispenser (10, 32) also includes a nozzle (16) and a nozzle plate (14, 14') that are formed from a dimensionally stable material in order to provide accurate control of the dispensing rate and the position of the nozzle. These features facilitate utilizing the dispenser (10, 32) as a portion of a multiple nozzle dispenser system (32) that accurately controls the rate at which material is emitted.
