LIQUID ATOMIZING PUMP

摘要

The invention relates to a liquid atomizing pump comprising the following elements: (a) a jacket (1) defining a longitudinal axis (7); (b) a piston (3) that can be inserted at least partially into the jacket (1) and that can be displaced along the jacket (1) in the direction of the longitudinal axis (7); (c) at least one annular lip (15) flanging a section of the piston (3) perpendicular to the longitudinal axis; (d) a hollow inner space (17) defined between the jacket (1) and the piston (3) and (e) at least one rib (19) in the piston occupying at least partially the hollow inner space (17).
