Apparatus for measuring and atomizing a predetermined quantity of liquid. Compressed atomizing gas is supplied through a passage to an atomizing nozzle. A finger actuated plunger moves a piston pump for measuring and delivering the predetermined quantity of liquid from a reservoir to the nozzle. The displacement of the piston is varied to change the predetermined quantity of liquid delivered to the nozzle. An optional gas pressure relief passage may extend from the gas passage through the plunger for reducing gas flow to the nozzle when the apparatus is not in use. When a finger is placed on the plunger to operate the pump, gas flow to the nozzle is reestablished.
