ABSTRACT:
A volumetric meter for liquids and/or gases, in the radial cavities of the rotor of which there are housed rolling rollers which, by undergoing mutual repulsion by the action of magnets embedded in them, are urged radially into a sealed state against the inner surface of the cylindrical chamber, which is provided in positions straddling said opposite maximum and minimum clearance zones with two portions having constant curvatures with their centre on the rotor axis and extending through an angle equal to the angular pitch between two successive rollers, i.e. to 360.degree. divided by the number of rollers used. Further inlet and outlet ports cooperating with the rear space in the housing cavities are also provided, as are fine adjustment means.
