Abstract
A proportional metering method and its associated pump, which includes: a hydraulic machine enclosing a member suitable for performing an alternative movement, supply to the machine at the inlet triggering an alternative translational movement by the member, a volumetric pump, provided with a rotational axis, an inlet intended to be placed in fluid communication with an additive tank, and an outlet in fluid communication with the outlet of the machine, a movement converter for converting the alternative translational movement of the member into a rotational movement, the rotational movement being transmitted to the rotational axis of the volumetric pump, such that supplying the machine operates the volumetric pump, which thus supplies the outlet of the hydraulic machine with additive.
