- The hydraulic fluid flows to the axial direction smoothly and extremely quietly because of no sharp pressure change.
- As the quantity of discharged hydraulic fluid is constant irrespective of the revolution position of an axis, there hardly occurs a pressure pulsation.
- As the idler rotor auto-rotates by the delivered hydraulic fluid and the biting power between the rotors is small, little wear and a long life is achieved.
