Abstract
A method of suppressing a pulsation of axial type hydraulic pump/motor includes performing a pressure accumulation operation in which each of ports of each of two pressure accumulation oil passages exclusively communicates with a corresponding one of communication holes and pressure inside one of the cylinder bores is accumulated in a corresponding one of the pressure accumulation oil passages through the communication hole in two levels, the communication holes being provided for each of the cylinder bores to communicate with inside of each of the cylinder bores and having opening portions sliding on the respective ports with rotation of the cylinder block to communicate with the respective ports; and performing an accumulated pressure collection operation in which the pressure accumulated in the pressure accumulation oil passage is collected in one of the cylinder bores in two levels.
