Abstract
An improved manually actuated liquid-atomizing pump assembly for non-pressurized pharmaceutical atomizers comprising a pump actuator unit and a pump unit, which causes a spray of substantially the same particle size spectrum to be discharged from the atomizer nozzle with each actuation of the pump; the improvement resides in a resilient mechanical resistance interposed between the manual pump actuator and the pump, where the resilient resistance requires a very definite amount of force to be overcome.
