Claims

[Claims for Utility Model Registration] (1) An inlet port for introducing a fluid into the interior of the body and an outlet port for leading out the fluid are defined, and a fluid passage is defined inside the body by a first diaphragm. A valve body is provided that defines a balance spring storage chamber to be shut off and that blocks the flow of fluid introduced from the inlet port under the action of the first diaphragm, and is further provided in proximity to the outlet port and connected to the first diaphragm. A second diaphragm is disposed opposite to each other, the first diaphragm and the second diaphragm are engaged by a rod, and a throttle is interposed between the inlet port and the outlet port. Constant flow valve. (2) In the constant flow valve according to claim 1 of the utility model registration claim, the rod disposed between the first diaphragm and the second diaphragm is configured separately,
The constant flow valve is configured such that each rod extends into the balance spring chamber from the holding member of the first diaphragm and the holding member of the second diaphragm so as to be able to freely engage with each other.
