ABSTRACT:
A pump-type atomizer is disclosed having a movable nozzle head and plunger that are operatively associated with a stationary cylindrical element. The cylindrical element has an upper portion and a lower portion, the lower portion having a tapered configuration such that its diameter decreases in a direction away from the upper portion. A valve element within the cylindrical element has a valve body which cooperates with a passage in the plunger to normally close the passage. The valve element also has a piston which, when the nozzle head is depressed, cooperates with the lower, tapered portion of the cylindrical element, in cooperation with the plunger, to enclose a portion of the liquid. Further movement of the nozzle head increases the pressure on this fluid, which overcomes a biasing force on the valve to open the valve and allow the fluid to pass through the passageway and exit through the nozzle head.
