THERE IS DISCLOSED A ROTOR PUMP ASSEMBLY WHICH REDUCES NOISE EMITTED FROM AN OIL PUMP WHILE PREVENTING PUMPING PERFORMANCE AND MECHANICAL EFFICIENCY THEREOF FROM BEING DECREASED BY PROPERLY FORMING THE PROFILES OF TEETH OF AN INNER ROTOR AND AN OUTER ROTOR WHICH ARE ENGAGEABLE WITH EACH OTHER. THE TOOTH PROFILE OF AN INNER ROTOR (110) AND/OR AN OUTER ROTOR (120) HAS CURVED LINES OBTAINED BY DIVIDING A CYCLOID CURVE INTO TWO SEGMENTS TO BE SEPERATED FROM EACH OTHER, AND IN WHICH THE SEPARATED SEGMENTS ARE SMOOTHLY CONNECTED TO EACH OTHER USING A STRAIGHT LINE OR CURVE.
