  • Volumetric metering device for container filling machine
    Patent number: 10926897
    Abstract: Some embodiments relate to a metering device, including: a metering chamber; a piston separating the metering chamber into a supply compartment and a metering compartment, the piston including a passage between the two compartments; a valve for closing the passage, allowing the passage of the product when same is in the open position; and movement mechanisms of the valve. The valve includes drive mechanisms of the piston arranged on either side of the piston in such a way that the movement of the valve in a discharge direction drives the movement of the piston in the discharge direction and the movement of the valve along the length of the cylinder body in a transfer direction, and drives the movement of the piston.
