・モータ。(1) The swash plate is semi-cylindrical, and the arc side and pump
The inner wall surface of the casing of the motor forms the tilting and sliding surface of the swash plate, and the flat side of the swash plate serves as the sliding and rotating surface of the shoe, which is spherically connected to the piston. In a swash plate type axial piston pump motor in which the tilting angle of the swash plate is changed by a servo piston, a flow path is formed in the swash plate that opens on the tilting sliding surface of the swash plate, and the piston reciprocates between the mater shoe and the piston. A swash plate type axial piston pump characterized in that an open flow path is formed in a moving cylinder block, and oil in the cylinder block is supplied as lubricating oil to a tilting sliding surface of a swash plate through these flow paths. ·motor.
