The present invention provides a bi-rotational charging pump for heavy equipment, characterized by including: a pump plate having a shaft hole through which a shaft passes on the center and an intake port for supplying a fluid to be received and a discharge port for guiding the fluid to be discharged formed on the top surface to be symmetric in both sides of the shaft hole; a pump cover formed to cover the top surface of the pump plate, having an internal operation space, and having a semicircular guide groove recessed on the underside of the top surface; a pump case installed in the operation space of the pump cover to rotate and having a receiving hole wherein the upper end of the shaft is received on the center, an internal rotor chamber eccentric from the center of the receiving hole, and a movable protrusion formed to move along the guide groove of the pump cover; and a rotor unit composed of an outer rotor installed inside the rotor chamber of the pump case to rotate and having internal tooth-formed protrusions on the inner circumference and an inner rotor positioned inside the outer rotor, having outer tooth-formed protrusions on the outer circumference, and rotated by the shaft. The bi-rotational charging pump for heavy equipment is capable of preventing a fluid leak in the case of the discharge of the fluid while maximizing a fluid intake, selectively changing a discharge direction, and enabling stable operation. |
