In a oscillating swash plate type piston pump/motor that oscillates via a freely connected return piston mechanism, the lubrication of the sliding surface between the inner surface of the housing and the cam rotating swash plate is provided by the tilt angle transmitting arm and the cam rotating swash plate. A pump that lubricates the swivel joint with the return piston mechanism.
A swinging swash plate type piston pump/motor configured to operate using motor self-load pressure oil. (2) The pump/motor self-load pressure lubricating oil for the sliding and swinging surfaces is guided from the universal joint via an oil passage continuously drilled inside the tilt angle transmitting arm and the cam rotating swash plate. The oscillating swash plate type piston pump/motor according to item 1.
