概要

In this paper, the pressure losses that occur in the cylinder port of an axial piston pump are analyzed and the critical condition for a suction operation is obtained. And using a simulated model of a rotating cylinder block, the values of loss coefficients that appear in the analysis are examined experimentally. As the result of this investigation, it becomes clear that, for the purpose of improvement of suction performance, the radius of pitch circle of cylinder ports should be small and the crosssectional area of cylinder ports should be large.
