Device for dispensing fluids

Abstract

The invention is a fluid dispensing device suited to be connected, by means of a connection element (), to a container (C) holding the fluid that can be dispensed from the inside to the outside of the container through an actuator element (), comprising: a suction duct () suited to communicate with the fluid held inside the container (C), a dispenser duct () in communication with the outer space with respect to the volume (V) enclosed by the container (C), a suction/compression chamber () that can communicate with the suction duct () and the dispenser duct (), a suction valve () suited to alternatively allow and prevent the passage of a fluid between the suction duct () and the suction/compression chamber () when, respectively, the suction valve is closed and open, a dispensing valve () suited to alternatively allow and prevent the passage of a fluid between the dispenser duct () and the suction/compression chamber () when, respectively, the suction valve is closed and open, a tight membrane () slidingly coupled with the walls of the suction/compression chamber () so that it can be translated in a predetermined direction; both the suction valve () and the dispensing valve () comprise the membrane (). The invention concerns also a system for containing and dispensing fluids (F).
