The centrifugal vacuum motor has three concentric vaned centrifugal rotors (R1-3) which rotate in opposite directions to the adjacent rotor. The rotors are driven by a central shaft (5) and side flanges (20,21) by pinions (16) which invert the rotation. The expulsion of the molecules of liquid causes a vacuum which increases across the faces of the rotors. The difference in pressure between the two faces of the larger flange causes the propulsion force.
