摘要：
A new distributing mechanism consisted of three-way spin valve was proposed in order to solve the problem of high speed distributing that the check valve distributing mechanism, which was commonly used in single piston pumps, could not satisfy. The mechanism could meet the need of high speed distributing. The check valve distributing mechanism and the designed spin valve distributing mechanism were analyzed by AMESim modeling. Results show that it cannot distribute at the speed of 2 000 r/min with the check valve. It can still distribute at the speed of 12 000 r/min with the spin valve. A prototype was conducted to test the performance of the single piston pump as well as the spin valve distributing mechanism. The test results of piston chamber's pressure accorded with the simulation results, indicating that the proposed spin valve distributing mechanism was suitable for the high speed single axial piston pumps to analyze the piston chamber's pressure characteristics. © 2016, Zhejiang University Press.
