    • PROBLEM TO BE SOLVED: To prevent the fixation of a fluid at the axial direction end face and the like of a gear, and the reduction and the variation of the discharge amount at the discharge port of a gear type quantitative pump. SOLUTION: A self-lubricating strengthening type of gear type quantitative pump discharges a fluid from a discharge port 9 at a constant flow rate by providing a gear couple 1 and 2 rotating at a constant speed while engaging each other, in a flow passage for force feeding communicating from a suction port 8 to a discharge port 9, and furthermore, the axial direction end faces of the gear couple 1 and 2 are lubricated by the fluid sucked from the suction port 8. The axial direction end faces of the gears 1 and 2 have ring form seal surfaces 10 in order to prevent the leaking of the fluid more than necessary at the shaft direction end surface of the gears 1 and 2, and recesses 11 formed at the inner sides in the radial direction of the seal surfaces 10 in order to prevent the stagnation and the fixation of the fluid at the axial direction end faces of the gears 1 and 2. Furthermore, flow passages 11, 12, 13, 14, and 15 in order to exhaust the fluid leaked at the axial end faces of the gears 1 and 2, to the outer side of the self-lubricating strengthening type of gear type quantitative pump rapidly, are also provided.
