Claims

[Scope of utility model registration request]

A diaphragm is installed between the cylinder chamber located in the center of the working fluid chamber and the valve chamber through which the supply fluid passes.
The piston in the cylinder chamber is reciprocated by a cam disposed in the hydraulic fluid chamber, and the hydraulic fluid in the hydraulic fluid chamber is sent through a conduit and a pore in the cylinder chamber, and a portion of it is transferred to the cylinder chamber. In the diaphragm pump, the supply liquid is discharged to the working liquid chamber through a passage opening to the valve, a check valve, and an overpressure valve, and the supply liquid inside the valve chamber is pumped by vibrating the diaphragm. A cylinder chamber and a piston are arranged at two positions 180° symmetrical to the cam, and the piston is reciprocated during one rotation of the cam, and the hydraulic fluid in the hydraulic fluid chamber is alternately circulated into the cylinder chamber. The feature is that the supply liquid in the valve chamber is alternately pumped, and two check valves are installed beyond the valve chamber, and the supply liquid that is pumped from the two pumps is combined to efficiently pump the liquid. Dual diaphragm pump.
