ABSTRACT:
A pump consisting in a rotor (3) realized like a housing, placed in an outer housing (2), inside the rotor a cylindrical element (6) coaxially connected thereto by means of an elastic band (23) forming lobate chambers (13,14) between the rotor and the cylindrical element (6). Inside the cylindrical element (6) a solid cylindrical element (9) with a head (10) flared in the shape of a hexagon is rotating inserted, said cylindrical element (9) engaging with an hexagonal pin (11) fixed in an eccentric position on the closing part (12) of the pump. Thus an eccentric rotation of the cylindrical element (6) is caused and, consequently, the compression and the expansion of the chambers for the expulsion and the suction of the liquid (FIG. 1).
