The present invention relates to a piston-type fluid pump, and the purpose of the present invention is to provide a piston-type fluid pump configured such that the rotation movement of a son gear, which meshes with a mother gear and rotates, is converted into a reciprocating movement of a piston by a connecting rod connected to an eccentric shaft of the son gear. The piston-type fluid pump according to the present invention comprises: a housing; a cylinder; a piston; a mother gear; a son gear which meshes with the mother gear and rotates; a connecting rod for connecting the son gear and the piston; and a cylinder, wherein the cylinder is provided with a fluid intake opening and a fluid discharge opening. In addition, driving of the piston-type fluid pump according to the present invention is configured such that, when the mother gear is rotated, the son gear, which meshes with the mother gear, rotates, and the connecting rod, which is connected to the eccentric shaft of the son gear, causes the piston to reciprocate inside the cylinder, thereby drawing and discharging a fluid. In addition, the piston-type fluid pump according to the present invention is configured such that one rotation of the mother gear is followed by reciprocating movements of multiple pistons on the circumference of the mother gear. In addition, the cylinder has valves provided for the fluid intake opening and the fluid discharge opening, respectively, such that the discharge opening valve is closed when the fluid is taken in, and the intake opening valve is closed when the fluid is discharged. In addition, the piston-type fluid pump according to the present invention is technically characterized in that a flowing fluid, such as air, water, oil, etc. can be used therefor. |
