The working principle of the Italian ATOS vane pump is similar to that of a single-acting vane pump. The only difference is that the stator surface is composed of eight parts: two long-radius circular arcs, two short-radius circular arcs, and four transition curves. Furthermore, the stator and rotor are concentric. When the rotor rotates clockwise as shown in the diagram, the volume of the sealed working chamber gradually increases at the upper left and lower right corners, indicating oil suction.

The operating principle of the ATOS vane pump is similar to that of a single-acting vane pump, the only difference being that the stator surface is composed of eight parts: two long-radius circular arcs, two short-radius circular arcs, and four transition curves. Furthermore, the stator and rotor are concentric. When the rotor rotates clockwise as shown in the diagram, the volume of the sealed working chamber gradually increases at the upper left and lower right corners (the suction zone), and gradually decreases at the lower left and upper right corners (the pressure zone). A sealing zone separates the suction and pressure zones. With each rotor revolution, each sealed working chamber completes two suction and two pressure actions, hence the name double-acting vane pump. The two suction zones and two pressure zones of the pump are radially symmetrical, and the hydraulic pressure acting on the rotor is radially balanced, therefore it is also called a balanced vane pump.
The instantaneous flow rate of an ATOS vane pump is pulsating, and the pulsation rate is small when the number of vanes is a multiple of 4. Therefore, the number of vanes in a double-acting vane pump is typically 12 or 16.
