A hydraulic radial-piston pump has a body, a rotor, guide ring, fixed pin and pistons, the pistons are in form of balls and are packed by means of a bushing. The pistons rest on continuous movable parts that are in contact with inner surface of the bushing. The parts that are placed between the pistons are in cylindrical form with convex end surfaces that repeat form of the pistons (in zone of contact with the pistons), and the parts placed at exit of the bushings have one convex end surface, in zone of contact with the pistons, the opposite – flat one. |
