From the movement relationship between constant power variable mechanism,acting force of constant power control valve and contact roller was analyzed,equation of inclined piston was derived,function relationship between the angle of screw swash plate and the displacement of inclined piston was calculated,mapping from the angle of screw swash plate to working pressure and out flow was established,constant power control principle error of variable pump with inclined piston was proved.
