ンプ・モーター。 The rear end of the cylinder block, which rotates around the central shaft, is slidably in contact with the front face of the rotatable valve plate, which is in slidable contact with the end plate of the casing. In an axial piston pump/motor in which the front ends of pistons inserted in a plurality of axial cylinders are slidably supported on a swash plate, each of the pistons is inserted in an overlapping manner between the valve plate and the end plate, and each has a suction port. and first and second spacer disks having discharge ports, and spacer disk interlocking means for rotating the first and second spacer disks at a constant ratio in conjunction with rotation of the valve plate. Axial piston pump motor featuring:
