Abstract
The invention relates to a vane pump (1), comprising an electrical drive unit having an electric motor and a motor shaft (6), a pump chamber (2) connecting to the electrical drive unit, and a pump ring (3), and a rotor (4) disposed concentrically to the motor shaft (6) within the pump chamber (2) and operationally connected to the motor shaft (6), wherein the rotor (4) comprises a number of guide slits (40) extending inward from the outer circumference of the rotor, in each of which a slider (5) having two opposite slider ends (50, 51) is displaceably disposed. The slider ends (50, 51) of each slider (6) are mirror symmetrical about the transverse center plane thereof.
