Abstract
A piston pump configured to suction and discharge a working fluid includes a plurality of pistons, a cylinder block accommodating the pistons, a shaft combined with the cylinder block, swash plate configured to reciprocate the pistons in accordance with rotation of the cylinder block, a casing accommodating the cylinder block, and a valve plate placed between the cylinder block and the casing. The valve plate has a suction port providing communication between capacity chambers and a suction passage, and the suction port is a cutout part formed by cutting out an outer edge of the valve plate.
