摘要：
A variable displacement distributor for axial piston pump/motor with pilot operated check valve controlling the effective output of each piston unit was presented based on valve control and virtual variable displacement theory in order to improve the total efficiency of variable displacement axial piston pump/motor. The operate principle of the valve controlled variable displacement mechanism was introduced. A computer simulation model was established based on AMEsim, and the valve controlled variable displacement mechanism was applied to a bent axis piston motor to construct a prototype. Both the simulation results and the test results indicate that the variable displacement distributor can continuously adjust the displacement of pump/motor. The distributor has potential advantage of high volume efficiency and can simplify hydraulic system.
