Claims

[Claims for Utility Model Registration] 1. A diaphragm is provided between the central center body and a pair of covers on both sides thereof, and these diaphragms partition a pressurizing chamber on the center body side and a drive chamber on the cover side. By connecting both diaphragms to both sides of a rod that penetrates the center body, and displacing both diaphragms by alternately supplying and discharging driving fluid to a pair of driving chambers, the main fluid is pressurized in a pair of pressurizing chambers. In a diaphragm type pump configured to alternately discharge the diaphragms, the pair of diaphragms are connected at their centers near the center hole of the center body, and the rod is slidably inserted into the center hole and supported by the center body. A diaphragm type reciprocating pump characterized by: 2 A diaphragm is provided between the central center body and a pair of covers on both sides thereof, and these diaphragms partition a pressurizing chamber on the center body side and a drive chamber on the cover side, and a rod passing through the center body is provided. By connecting both diaphragms on both sides of the diaphragm and displacing both diaphragms by alternately supplying and discharging the driving fluid to the pair of driving chambers, the pressurized main fluid is alternately discharged in the pair of pressurizing chambers. A diaphragm type reciprocating pump characterized in that the pair of diaphragms are tube-shaped, each having the pressurizing chamber formed therein, and the rod is inserted into the center of the diaphragm. 3 A diaphragm is provided between the central center body and a pair of covers on both sides thereof, and these diaphragms partition a pressurizing chamber on the center body side and a drive chamber on the cover side, and a rod passing through the center body is provided. By connecting the central parts of both diaphragms to both sides of the diaphragm and displacing both diaphragms by alternately supplying and discharging driving fluid to a pair of driving chambers, pressurized main fluid is alternately discharged in a pair of pressurizing chambers. In the diaphragm type pump, a recess for accommodating the center diaphragm is provided in the center hole of the center body that supports the rod, the outer peripheral edge of the center diaphragm is fixed to the inner periphery of the recess, and the rod is attached to the center diaphragm. A diaphragm type reciprocating pump characterized in that a cylindrical part for being attached to the surface of the pump is arranged in series, and a center diaphragm partitions a pair of pressurizing chambers.
