ABSTRACT:
An apparatus for providing variable doses and variable spray patterns for a dispensing pump is disclosed. The actuator assembly can include two spray nozzles with different spray patterns, and a mechanism for allowing fluid communication between the pump interior and either one or the other of the two spray nozzles. The actuator assembly also includes a mechanism which limits the downstroke of the pump piston by providing a stop mechanism which limits downward depression of the actuator assembly.
