Abstract (en)
The dispensing pump (1) comprises a hollow body (3) defining a suction and compression chamber (4) for fluid (F) to be delivered, communicating with the inner room of container (C) through a suction duct (4a). A first tight piston (5) is slidingly coupled to the hollow body and is slidingly and coaxially coupled to an end (6) of a second piston (7), internally provided a tubular chamber (8). Passage of fluid through a hole (13) is intercepted through a first shaped rim belonging to the first piston and sealingly coupled according to the mutual position of the two pistons with a corresponding second shaped rim of the second piston. There are at least two discreet annular sealing zones between the two rims.
