Claims

[Claims for Utility Model Registration] A body, a pair of covers on both sides of the body, and a pair of displacement members connected to both sides of a shaft that closely penetrates the body, each pressurizing chamber on the outside of the displacement member,
Through an inlet check valve that only allows fluid to flow in and an outlet check valve that only allows fluid to flow out,
A diaphragm pump having a directional control valve connected to the inlet port and the outlet port of the main fluid and provided in the body with a directional control valve for supplying and discharging driving fluid to each drive chamber inside the displacement member, wherein the directional control valve is installed in the body. In addition to establishing
The directional switching valve includes a detent mechanism having an occluded circular detent spring installed in a groove of the valve hole so as to be expandable and retractable in the radial direction, and a locking protrusion formed in the valve body and with which the detent spring locks. A diaphragm pump with a day tent mechanism.
