  • Self-calibrating return spring pump, in particular self-calibrating return spring dosing pump
    Patent number: 10267297
    Abstract: Self-calibrating return spring pump (300; 400), in particular self-calibrating return spring dosing pump, configured to carry out a volume pumping of a fluid (190) in a variable-volume front chamber (180), the self-calibrating pump (300; 400) being provided with a rear chamber (200) housed in a lantern (205) and with movable mechanical means (140, 150, 160; 140; 150) for forming a movable wall (170; 340) of the rear chamber (320) and for causing the movable wall (170; 340) of the rear chamber (320) to make a reciprocating motion when said movable mechanical means (140, 150, 160; 140; 150) interacts with cam or eccentric mechanical means (110), the front chamber (180) being configured to increase in volume when the rear chamber (200) decreases in volume and vice versa, the pump further comprising elastic means (210) for elastic return of said movable mechanical means (140, 150, 160; 140; 150), the pump being characterised in that the rear chamber (320) is provided with one-way valve means (310) configured to a
