Abstract

Axial hydraulic pressure unbalanced defect of axial piston pump restricts its application scope.The Author assumed a piston pump which can realize the balance of axial hydraulic pressure through changing shapes of swashplate and port plate,and we could adjust the geometic displacement of pump by a change of the plunger stroke.The working principle of the double-sided swashplate piston pump which the paper briefly introduced may be used as reference and for further research.
