Abstract：

In　order　to　develop　a　new　type　of　high-performance　axial　piston　pump,　the　impact　of　the　dynamic　response　characteristics　of　piston　chamber　pressure　to　the　stability　of　cylinder　block　were　analyzed.　This　paper　a　new　type　of　valve　plate　which　combined　two　fixed　throttling　grooves　with　a　triangular　groove　(called　three-level　gain)　was　put　forward　so　as　to　reducing　the　excessive　pressure　adjustment　of　the　dynamic　response　of　piston　chamber　pressure　and　improving　the　stability　of　cylinder　block.　The　simulation　results　indicate　that　not　only　the　cavitation　is　reduced,　but　also　the　stability　of　the　dynamic　response　of　piston　chamber　pressure　is　remained　at　various　swash　plate　angle　which　makes　it　applicable　to　variable　piston　pump.　The　results　also　indicate　that　the　flow　pulsation　of　variable　displacement　pump　is　significantly　decreased　in　different　operating　conditions.　©　(2014)　Trans　Tech　Publications,　Switzerland.
