Improvements in the high vacuum fin pumps of the class comprising an eccentric with an oscillating tubular rotor that remains tangent inside the cylindrical body, and that is guided by a vane, which is characterized in providing the tubular rotor and in the longitudinal direction of a cylindrical cavity axially parallel to the axis of said rotor and internal tangent to its cylindrical surface or very close to the tangent position, but always linked with said surface by a cut with the chamfered edges, making the single vane, independent of such rotor and endowed at one of its ends with a cylindrical part that fits into the cylindrical cavity of the rotor with possible oscillation.
