摘要： PROBLEM TO BE SOLVED: To provide a small gear pump that is formed to be flat in a roughly disc-like outer form to prevent generation of useless space around an installation place so as to improve space efficiency.
SOLUTION: In this small gear pump, a disc-shaped case 11 is used, and in the case 11, a flat rotor chamber 12, a shaft bearing part 13, and a flat and cylindrical gear chamber 14 are formed in order to be communicated with each other. In the small gear pump, pipes 15 and 16 are provided to separately communicate the rotor chamber 12 and the gear chamber 14 with the external. In the case 11, a rotary shaft 18 is provided, with a lower end journalled in a radial direction and a thrust direction by a first bearing 19, an outer circumference at an axial direction intermediate part journalled in the radial direction by a second bearing 20, and an upper end reaching into the gear chamber 14. In the rotor chamber 12, a disc rotor 22 integrated with the rotary shaft 18 is provided to be driven to rotate by a stator 23 provided on an outer surface of the case 11. In the gear chamber 14, a trochoid gear 25 is provided, with an inner rotor 27 driven to rotate by the rotary shaft 18 to act as a pump with an outer rotor 26, so that fluid is taken into the pipe 15, and discharged out of the pipe 16.
