Components of an Axial Piston Pump. An axial piston pump typically consists of three primary components: the cylinder block, pistons, and swashplate. The cylinder block houses multiple pistons arranged in a circular or semi-circular configuration. As the swashplate tilts, it imparts reciprocating motion to the pistons, creating suction …
