Abstract (en)
[origin: WO2010131103A2] The invention relates to a single-vane pump comprising a stator (11), a first rotor (13) mounted in the chamber (20) of the stator and capable of rotating around an axis (M-M) and a vane (12) slidably mounted in a diametric groove (30) of the rotor (13) and having a rectilinear portion (26) having a predetermined length (L) and opposite free ends (22, 24) in contact with a perimetric surface (lib) of the chamber (20). A second rotor (14) is mounted in the chamber (20) and is capable of rotating around an axis (0-0) which is parallel to the axis (M-M). The vane (12) is pivoted to the rotor (14), at a longitudinal middle area thereof, on an axis (P-P) parallel to the axis (M-M). The distance between the axis (M-M) and the axis (0-0) and between the axis (P-P) and the axis (0-0) is equal to a fourth of the length (L) of the rectilinear portion (26) of the vane (12). The perimetric surface (lib) of the chamber (20) has, in a plane perpendicular to the axis (M-M), a cardioid shape that coincides with the cardioid defined by the ends (22, 24) of the vane (12) during the rotation of the rotors (13, 14).
