ABSTRACT:
A dosing or atomizing pump for liquid, creamy or pasty media has, in addition to its outlet valve provided on the pump chamber an additional valve provided in the pump operating pushbutton and closes the discharge opening directly at its mouth. By means of the hydraulic pressure, the additional valve body is operated by means of a differential piston. In a variant, the valve body can be a functional part of an atomizer nozzle. The additional valve prevents drying or other negative influencing of the medium in the discharge passage.
