摘要： Variable displacement oil pump (110) comprising a pump body (112) connected to an intake channel (112a) and to a delivery channel (112b), a rotor (114) capable of rotating inside the pump body (112) about a rotation axis (O) and provided with a plurality of vanes (118), an oscillating stator (122) arranged in an eccentric position around the rotor (114) and pivoted inside the pump body (112) at a rotation pin (123), and adjustment means (126) for adjusting the displacement of the oil pump (110) which acts on the oscillating stator (122) to displace it with respect to the rotor (114). The adjustment means (126) comprise first thrusting means (130) configured to exert a first thrusting action on a first outer surface portion (122a) of the oscillating stator (122) arranged on a substantially opposite side with respect to the rotation pin (123) taking as a reference the rotor (114). They further comprise a thrusting chamber (128) defined between the pump body (112) and a second outer surface portion (122b) of the oscillating stator (122) arranged between the rotation pin (123) and said first outer surface portion (122a). The thrusting chamber (128) is configured to be filled with a predetermined amount of a pressurised fluid to exert on the oscillating stator (122) a second thrusting action opposite to said first thrusting action and suitable for displacing the oscillating stator (122). The thrusting chamber (128) is fluid-dynamically insulated from the rotation pin (123) by two opposite sealing gaskets (132, 133). Between the thrusting chamber (128) and the rotation pin (123) an insulation chamber (134) connected to an intake conduit (112c) is defined.

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).
