The working oil flows smoothly along the axial direction, and the noise is very small because there is no drastic pressure change.
The amount of oil output is independent of the rotation position of the shaft, so there is almost no pressure fluctuation.
The driven screw rotates through the output working oil, because the meshing force between the screw parts is very small, so the wear and tear is small and the service life is long.
