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.
